Mazda - B3000 :: 2001 - Misfire On Startup
Oct 22, 2016
I'm having an issue with a misfire whenever I start my truck. It happens regardless of whether the engine is hot or cold, and lasts for about 10 minutes. I had a similar issue not too long ago, except last time it just stopped starting all together until I had the injectors cleaned. I have new plugs, wires, new coil pack, and a semi recently replaced fuel filter. I'm hesitant about it being the injectors stuck open again as its only been about 1000 miles since I had them all cleaned.

As the title states, I have a 2002 Mazda B3000 series Pickup and while everything is working great, the a/c is driving me insane!
Here's how it goes:
- Start the car, turn on the A/C, hear a click
- As I drive, after 10-20 minutes, the A/C would just either switch to (what I think is) vent; it blows humid, warm air.
- Another way to turn it off is to accelerate quickly; Note: these two scenarios are sometimes inconsistent
- Sometimes, it would occur, while other times it would just randomly turn itself off
- A solution I've found is to switch over to vent, leave it on there for a few minutes, then switch back to A/C; works for another 10-20 minutes
What I have done to fix it is to replace the freon (even though, it was never really empty; still isn't empty) and have replaced the fuse associated with the A/C.

The garage said that the "carrier bolt" is broken. What is this and is it a harbinger of more death to follow? This truck is rowdy and distrustful to drive to begin with.

I have a 99 Mazda b3000 v6 that has recently started to stall whenever in idle. Check engine light is on and the following codes popped up (P0176, P0135,P0141, and P0155). I'm sure one of these codes has to be related to the problem but I am clueless when it comes to troubleshooting. Also it started stalling after I filled up the tank. Not sure if that has anything to do with it, check engine light was already on before that.

2001 M B3000 v6 my sons truck w 122k. He is overseas and I took it to deliver a CB750 bike to my brother in law... 4oo miles away from my place.
In the middle of nowhere TX it developed a bad miss or knock, almost a shudder in the 2 to 3 k rpm range. Idles ok just below 1k runs fine at 70 mph as long as the rpm is near or over 3k.
Not sure I want to turn around and drive back the 400 with it running like crap. I will take it to Autozone and pull codes tomorrow a.m. but what should I expect?

My 2007 Mazda3 2.0 engine had the CEL on. took to autozone... gas cap code cleared. After the code was cleared next times I filled up, whether empty or 1/4 tank, car wouldn't start unless gas pedal is pushed to floor. Took to dealer. Dealer said code was for gas cap and maybe a vacuum hose. Did something to gas cap and cleared code. Light back on 2 days later with hard start still there. Replaced vacuum hose... CEL off, now 2 days later CEL off but still has the startup after fill up problem. At $90/hr I'm hesitant to return to dealer.

I have a 2002 Mazda Tribute V6 with 151K. My check engine light has come off and on for quite a while now, mostly it would come on when it rained and then go off when the weather cleared. When it was on, the engine would sputter or misfire. I first had Auto Zone hook it up and they said it needed its plugs and wires changed. No problem. I took it in to a repair place and was informed that I don't have plugs and wires, but something with coils and that since it was impossible to determine which coil was bad, all would have to be replaced at a cost of $1500. I then took it to another repair place and they said the same thing. Now I have seen some discussions regarding this same thing and apparently some people have been able to identify a specific coil. At this point my check engine light is now on all the time and I'm really worried about doing terrible damage.

About two weeks ago I noticed the engine idle start to hesitate but ONLY while idling. I was sort of leaning towards the distributor cap or rotor but that didn't add up because in the past when either of these would go out the car would just die without any warning whatsoever. So I just kept driving it and then tonight when I started the engine it was hesitating a lot more than it had been and also hesitating during acceleration but would smooth out after I would reach and maintain 40mph. The CEL also started flashing on and off. I went ahead and replaced all the spark plugs, distributor cap and rotor with no improvement. Tomorrow I plan to replace the plug wires. The code it's sending is P0302 (misfire cylinder 2). If the plug wire doesn't do the trick and I can't find any leaks on the intake I'm going to try to figure out how to inspect the ignition coil (well, it shouldn't be too hard to figure out since I have two different shop manuals for this car.)
Another possibility for P0302 is low engine compression but I seriously doubt that's the problem because last time I checked the compression all 4 cylinders had above average compression. I doubt the plug wire is going to fix it since the wires only have about 20k miles on them and I don't think I have any leaks on the intake so where else I should look? Oh yeah, just remembered. I also put a stethoscope (actually a screwdriver) against the fuel injector for cylinder number 2 and it was clicking away just like the other 3 injectors so I guess the injector isn't the problem unless it can be faulty and still make the clicking noise. So should I check the injector with a meter or is the clicking enough evidence that it's working fine?

Mazda6. I have a check engine light for a random misfire on cylinder 2. I have changed the spark plugs, the injector, and even the cylinder 2 coil, but still have that random misfire. The funny thing is that it would run great within short (about 30 miles) one way trips. Lately, I have gotten a new symptom: It has started to hesitate and can feel a loss of power but only once the car has been driven for about ten minutes non stop. Can't figure this out.

I have a 2004 mazda6 v6 3.0 and it is throwing codes for o2 sensors. No cat but there is a code for heated o2 sensor. Not to Familiar with Mazda's but when accelerating hard below 3000 rpm it seems to misfire or skip. Only when accelerating hard though. If just barley pressing the pedal and slowly creeping through low rpms it runs fine. Anything above 3000 rpm it accelerates great.

I have recently purchased a 2012 facelift Tiguan diesel and it has a running fault. When starting the engine, 50% of the time it starts fine, 50% of the time it starts with a "misfire" and sputters for a short while (5-6 seconds) then stalls. If you Rev it a bit while it is sputtering then it clears the sputter and doesn't stall. It doesn't matter if it's hot or cold. Once it's running fine then the misfire never returns until you shut off the engine and then try to restart. The start stop also fails to cut in and I'm wondering if this could be linked. It had a new battery and alternator fitted a few months ago but a non start stop battery was fitted. This has now been changed for the correct battery but both problems still persist.

The check engine light on my 1999 1.8T Passat is on. It started with a little miss right after startup. Then in neutral, after revving the engine to say 1,500 rpm and letting off the gas, it would nearly stall. I plugged in an OBDII analyzer and came up with codes P0102 MAF or VAF circuit low input and P0304, Cylinder #2 misfire. I replaced the spark plugs, as they were old anyway. Still the same symptoms. Then I replaced the mass air flow sensor.
The check engine light still went on after it was cleared, except this time it was P0302, Cylinder #2 misfire, P0102, P1613, Auxiliary inputs aux. outputs control, and P1426 Mfg. Control/auxiliary emission controls. Soon after, the car started running fine on it's own and I again cleared the codes.
Then a day later, the check engine light is on. This time, it is only the P1426 - Manufacturer control auxiliary emission controls. The Bentley manual calls it Tank Vent. Valve Open, which doesn't mean anything to me and the Bentley manual is of no luck. (The error code almost implies that it is the famous loose gas cap, but I have checked that - unless the gasket is bad). FYI: I have 99K miles on the car.

Previously on "This Old Truck": [URL] ....
Mileage now 298,5xx. Done since last report: Oil change and filter. Trans oil change (merconIII, no leaks apparent). Tires. Front brake pads. Clutch safety switch (was interfering with cruise control operation) Coolant replacement. (see below)
Rat damage related overheat (near total coolant loss, but no MIL) at 288k. (Rat suffered acute lead poisoning later that night) No sign of rodents since.
Fuel filter change (after onset of symptoms).
NO MIL/CEL, no pending codes. CEL/MIL operates on KOST.
Temps normal (190F +/-2 deg during steady-state cruise operation, fuel flows and fuel mileage have not changed significantly. (fuel mileage has IMPROVED approx 5%, possibly due to gentler/slower driving)
M5OD with Limited slip 3.73/ payload pkg II (1650lbs)
Symptoms:
- Intermittent misfire on startup, seems to get better as the truck warms up. (intermittent= some days it do, some days it don't.)
- Truck starts and idles well, even with misfire.
- Intermittent loss of power, usually worse on days when no- or minor- misfire at startup/cold idle. From the driver seat it feels like accelerating over painted lines on a rainy day. . . a couple revs of no power, then it pulls hard for a second or two, then misses a couple of shots, lather, rinse, repeat.
- Usually worse in higher gears; (not noticeable in first or 2nd, bad in 3rd at high power settings, now almost constant in 5th, to the point that truck will not accelerate below 3000rpm in 5th even on flat ground.)
- Fuel flows above 4GPH/ OBDII "LOD" (engine load) reported above 75% are typical during malfunction. (Fuel flows have been as high as 9GPH with no problems on other days.)
Symptoms started at approx 292k and have been slowly getting worse over the past few months. . . . usually worse at beginning of trip, fading to very occasional after 50 miles of high-speed driving. Some days/trips no noticeable malfunction.
Thoughts:
1) Ignition wires tired? (did visual inspection, no obvious damage, but no water spray test performed, but seems likely given that the problem is most evident in conditions that would lead to high cylinder pressures.)
2) Fuel pressure? (not measured yet. . . original pump but possibility discounted due to intermittent nature of malfunction.)
3) O2 sensors tired/rat damage? (Original units still installed/ no obvious damage on cursory visual inspection under truck)
4) Injector going bad or injector wiring rat damage?
5) Plugged catalytic converters? (no sound of blown exhaust gaskets, exhaust flows well at tailpipe, with puffs at misfire.)
6) Cam sensor? (never been replaced; known issue with this model engine. Had intermittent mystery squeak that came and went at approx 250k-260k)
7) Clutch slipping? (never had one do that; always lose the throw-out first)
8) LSD problem? (fluid level/ appearance ok, last changed 150k; would expect worse in LOW gears)
9) Blown head gasket/s?
10) Cracked heads/ block? (Oil and coolant levels and appearance normal)
So: That's the plan of attack. What am I missing? (Clutch last done approx 170k; burned throw-out, did disk, flywheel, pressure plate, slave cylinder while the trans was down. I did not open the hydraulics or disturb the pedal linkage when I replaced the safety switch. )

My 2010 F-150 5.4 L has developed a misfire. I don't have the codes right now but can get them. Replaced all plugs and 3 of the 8 cops. Misfires right after startup but as it warms up tends to smooth out. When it is acting up it almost stalls out at stops. Where to next?

My g/f's 2004 Ford Escape (3.0L V6 AWD 112,000mi) is acting up. After a full day of sitting, with the second half of it raining steadily, she was driving her Escape and it was acting funny (miss-firing, she said). The engine light came on and soon began blinking. She got to my house shortly after it started this. We left it and I drove for the day. Later that night, I drove it and it seemed fine. The engine light was on, but not flashing anymore.
The next day I took it my friend that was a Saturn mechanic and now working at a KIA dealership (same owner as the former Saturn and current Buick/GMC and Chevy Dealer). It ran fine for me. So he tries to scan it, his Mac Tools scanner won't read it. The KIA scanner wouldn't read it. I drove it the Ford dealer up the road. They said they couldn't get to it until after lunch, I just want the codes read. They re-iterated, and I told them to pound salt and went to an independent shop where I know a guy. They read it right away for me. "Mis-fire on start-up" & "Cylinder 4 Mis-fire." were the two codes stored. He cleared them.
She got the tune up basics (plugs, wires, air filter, etc) and did the complete tune-up herself yesterday. (I was impressed). She put 94 in the tank and some fuel system cleaner in it as well. She said there's been no change and today I finally saw what it was doing. Sometimes during idling at a stop light, the RPMs will drop to almost zero, the lights dim but so far it has not stalled. It'll do this for several seconds, then correct itself and idle normally.
Currently, the engine light has not come back on. She's thinking coil pack (each cylinder has a coil on these engines) on #4. She wants to switch it out with #1 and see if the problem follows. I think that might uncover the cause, or it could be the battery. It's the original, never been replaced and has a lot of miles on it, but it survived this past winter, without trouble. In my experience, most batteries crap out due to age in the fall when the cold snaps start.

I've got a 96 Aero with 128k miles. It's AWD with the 4.0L. It's developed an annoying "stumble" on startup. The engine seems to misfire a bit and the car shakes. It goes away when I give it some gas and/or start driving. This started out being very occasional but eventually started happening at least once a day. It doesn't seem to happen with the engine very cold or very warm. It mostly happens when the engine is "lukewarm" (having sat for about an hour). So far, it hasn't died on me. I ran some fuel injector cleaner through and it went away for about a week, but then returned (but not as bad). No stored codes. Within the last 10k miles I have had done:
Compression test (passed) about 10k ago
New plugs, wires
New fuel pump
New water pump
New fuel filter
Tranny rebuild

We've got a 2006 F150 with a 5.4 in it. One of the new kids was told to change the spark plugs, then when I went to start the truck the next day it was missing bad. Plugged in the Ford IDS, number 7 cylinder is dead. Only codes are for that cylinder misfire, and random miss on startup. So, I double checked the kids work and it was all fine. Tried putting a new plug in, didn't work. Moved the coil to a different cylinder to see if the miss would jump, stayed on number 7.
Used a noid light to verify COP harness was working, and it was. Put a new coil on it anyway since I had one, still missing. Used noid light to verify signal going to injector for the cylinder. Signal was good, replaced the injector for the cylinder. Still misfiring. Ran a compression test and the cylinder has good compression. The threads for the plug are fine, not cross threaded or torn out. The only thing I can think is that the PCM has gone bad in a way that its firing the injector/COP, but doing so at the wrong time some how.
Every other cylinder is running fine, O2 sensors fine. PCM isn't trimming anything back to account for anything, and if it was it would do it to multiple cylinders to keep the engine balanced. Cant think of any more tests, and I don't believe there is anyway that the airflow could be restricted to only 1 cylinder, but I could be wrong. Wanna try and solve this to keep from sending it to the dealer.

The problem that causes the check engine light to come on cannot be traced. The diagnosis is multi engine misfire. The dealer has checked and recheckedbut problem still exists. The last time my mechanic changed spark plugs he noticed oil on one of the plugs he removed in the rear side of the engine. He replaced the plug with the rest of them. Could it be that one or more of the spark plugs are sucking oil and causes the misfire? If so what could be the cause of that. Do I need a full tuneup? My dealer recommends replacing the cam shaft pulley because it's loose and this may or may not solve the problem. I'm not a mechanic but it appears as if the problem has something to do with the spark plugs sucking oil since the check engine light might go ou for a week or so and then come back on for a while. Lastly is it dangerous to keep driving the car especially on long trips?
