Ford F-150 (2004-2008) :: Intermittent Starting - No Sputters / No Hiccups
Jan 13, 2007
Intermittent starting issue in these things? Seems to be getting more common for me this winter. Turn the key, it turns over, and then I let go of the key and she doesn't light. Then when I try again, it's like the engine is flooded. I have to give it gas to start, which I know is a no-no in fuel injected vehicles. Other than that, it's fine. No sputters, no hiccups, runs strong, good mpg, etc. But I'm getting annoyed....

After a while of running with the A/C on the car starts to have little hiccups? almost sounds like it's missing? but not that dramatic, it will continue after I turn the A/C off, but resolve after I have had the car off for a while. It will start up again after an hr or less of starting the A/C. It seems like I have a loose in HP while this is happening, more so than normally expected with the A/C on. I have recently replaced the ignition cables, plugs, my car is definitely a little more peppy now, and had the timing belt/water pump replaced, all the ussual maint, but this issue was present before. What this could be?

I have a 2006 F150 STX auto trans with the 4.2L V6 that has been having intermittent starting problems. It has 98,000 miles on it. It will start fine 99% of the time but sometimes when I turn the key the starter will grind once or twice then it can go a few weeks with out doing it at all. Then also sometimes it will crank turning over for several seconds but wont start. Then it starts fine the rest of the time. This has happened several times but only happens once every few weeks or so. Just trying to see if it needs a new starter or if its something else. It has a new battery.

I was getting a misfire in #4 cyl. Couldn't afford to change all my plugs, so I replaced the one that was missing. Two weeks went by, truck ran fine, then it started missing really hard (same cyl #4). Thought my COP was bad, so replaced that and the boot.
Drove my truck to work last night, seemed to run fine, but this morning, it started to sputter again around 45-55. Plug in my OBD2 and it wasn't throwing any codes, seemed to idle just fine.
When I got home I put it park and revved the engine a little bit. Got it around 2500 rpm and it sounded like I have a air leak in a way. What do at this point. It is a 2007 F150 5.4 triton with 104xxx on it.

Strange condition? If I kick it down hard into passing gear (or downshift hard into any gear for that matter), it pukes and sputters for a few seconds before clearing up and coming to life. No issues with normal driving, or dead stop hard acceleration, just on the downshift.
I’ve got a Magnaflow cat back on there and am wondering if opening up the exhaust and reducing the back pressure is screwing with the ECU a little? Is this just the nature of the stock Ford tune and it wasn’t as pronounced with the stock exhaust as it is now? Trucks an '06 FX4 5.4L and only has 70,000km on it.

When starting from a full stop our truck intermittently will act like there are air bubbles in the fuel line or something and will nearly stall out several times before it gets going. We don't have a problem while driving. The "hiccups" eventually got better after we began buying a different kind of fuel, but there is still a problem. We have had the truck looked at several times but no one can find anything wrong with it because the truck seems to always be on its best behavior when we take it somewhere. Except for this, the Dodge has been a great truck and pulled our 32' "house" all over the USA and Canada since we bought it brand new in 2003. We are very good about doing all the regular maintenance so the obvious answers can probably be ruled out. It has a Cummins diesel engine and we regularly add an additive to the fuel.

I got my truck to throw some codes. As many of you know I have been having an issue where when I stomp my truck to the floor it sputters and hesitates. Some days its worse then others. It only happens under a load, and it generally doesn't last to long, however today it did it a whole bunch and lasted for a good bit any time I got on it hard. My engine light begin to flash, and there was a smell of exhaust. I went to Autozone quickly as possible. The guy read the code, and this time no lean codes, just a "P0430" which the code reader said was O2 Sensor Bank 2. It also had a pending code, which was "multiple cylinder misfire detected". So my question is can an O2 sensor cause this? Could my CAT on that side be bad?
If that is all it is, is a bad cat or O2 sensor then I will be very happy... Like I said I can sit in my driveway in park all day long, and rev outta my truck. It will never misfire or hesitate at all. Soon is I put it in gear and am going down the road and punch it sometimes it pop and sputter.
Another cool thing is some how their code reader was able to read my ABS light, and I found out that this whole time I have had a bad ABS Speed Sensor in the rear end. That is a plus as well.

I've recently replaced the timing chains on my sons 04 F-150 5.4. Now I'm getting a code PO174. I've changed 2 coil packs, fuel filter, MAF sensor and cleaned all the connections. Fuel filter had what looked like brown fuel coming out of the in line of the filter. I'm stressed out now, the truck does not even have enough power to drive up the driveway. Backfires, spits and sputters, has rough idle.

I have had a 2005 f150 v6 5 speed for a little over two years. Got about 153k on it. Last night was sitting in a parking lot idling about 20-25 minutes, went to leave and she started sputtering hard, lost all power and died. Started back up, idled fine, as soon as i put it in gear same thing then the check engine light came on.

My 2008 Grand Prix has developed an intermittent starting issue. The car always starts in the morning. On some days after I have driven to work, grocery etc it refuses to start. Dead. No sound, no "click click". If the car sits for 15 minutes it will then start. The dealership has replaced the relay in the transmission that tells the car what gear it is in, replaced the battery and cables, suggested I try using my husband's key instead of mine. It still happens. It has done this about 7 times since October.

My truck's been having an occasional hard start, meaning the engine cranks strong but it fails to catch and then sputters. The 2nd start attempt usually fires up with no issues and then runs perfectly otherwise.
MPG's haven't changed, fuel filter was changed 15K ago. Air filter is clean. Plugs were changed about 10K ago. I always use Shell/Chevron gas. MAF sensor looked clean when I took it out so I didn't do anything to it.
This is starting to happen more frequently, maybe once every few weeks and I get a feeling it's the start of something. I've found myself waiting a few seconds for the fuel pressure gauge to come up before turning the key to start reliably. In the past, I could simply flick the key and it fires up the first time.
I see posts talking about the fuel pump module above the spare tire. What are symptoms of that going bad? Any pending codes that might be stored?
I'm about to get myself a scanner since I need one sooner or later. Which specific PID's to check while debugging this?

Ford E150 Conversion Van 1991, V8. Replaced spark plugs, wires, fuel pump, fuel injector, cleaned gas tank, replaced gas. Ignition turns and starts but sputters loudly and stalls soon after. We've tried just about everything but it won't stay running.

2004 Lexus GX470, for the last month experienced intermittent starting problems. Turn the key, one slight click first try,nothing after. Disconnect battery cable and reconnect, starts every time.
Then while driving a week ago the vehicle died, all electrical seemed fine, more like fuel cutoff. Now every attempt to start is the same sequence of events, first try one click. Second car turns over and won't start or if it does runs rough for a few minutes and dies.
Third try, the starter won't disengage until key is turned to off position.
Possibly the ECM? Immobilizer? It's obviously not a starter problem as disconnecting the battery caused it to start and now when it does start it runs rough and then dies.

I have a 1999 f250 super duty with the 5.4 Triton motor with a 5 speed. I bought the truck a couple months ago, and it had a bad manifold leak (not surprised lol). but it ran fine just noisy. So i had a shop do new gaskets and bolts. Then my problems started.........
When you start up the truck she runs fine and some times drives fine. I will be driving along and its like some one hits a switch and i suddenly loose all power it spits and sputters and i have to down shift to make any kind of hill.
So I figures I had a misfire i got a light on for cylinder 5. So I decided to change all coils and plugs hoping that would clear things up...... well it didn't. It ran great for roughly 15 miles then it started to do the same thing again. I've changed air filter and fuel filter also.
When it starts sputtering i sometimes get a check engine light on and then it goes away. when the light is on the codes are:
P1151 A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

P1152 Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2
Read more: P1152 FORD Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2 | AutoCodes
Both codes come on together always. but it will go away when the sputtering clears up. I just checked fuel pressure its at 32psi at a idle.

For a couple months now, maybe longer, my 2010 Accent has developed a funny "rough sputter" I would call it at idle. It seems to be getting worse and worries me now. The RPMs fluctuate as it happens. The CEL has never come on throughout this. I'm not 100% sure it's not present when driving.
I did not replace the Fuel Filter at four years or the Fuel Air Filter at two years & four years. Could this be a Fuel Filter related problem?
I got out of my car today to listen to it and noticed the exhaust was intermittent along with hearing the car sputter.

I have a 2004 Ford F-150 4x4 5.4 V8 SuperCab. Back in February I lifted my truck with 2.5in coil spacer adapters, out back add a leafs 2-3in. Now I can't say for sure it stated then, but for a while now I have an intermittent freeway vibration. Typically around 70-75mph it is at it peak when it does it. Other times it can be very smooth. The vibration is like an oscillation that you can feel in the body. Not much felt in the steering wheel. The vibration can start and stop any time and last for any amount of time, there is no common point for when it starts and stops. Right or left turns does not cause it to start or stop, sometimes it feels like big bumps will start or stop it but not all the time.
I have a rearview aftermarket camera, I took it off and mounted it several locations to view tires. The fronts are steady while at freeway speed and with the vibration.
After tie rods were changed and no play in any suspension/steering parts, the truck has been aligned several times. Tires are new and have been balanced twice. The driveshaft is new (new U-Joints, shaft and slip yoke) and is balanced, which it did improve the vibration but not perfect. The rear brakes have been inspected, no sign of overheating on the drum or the shoes. The lever is all the way back. So I don't believe it is it, although I did not fully disconnect the cabling. If it was the brakes why would it be intermittent? I had a shop replace all bearings in the rear axle, due to the pinon bearing noise. I saw the TSB's already on vibrations and none conform to my situation. The hubs have been checked, with the engine on they are unlocked.
So as I stated I can't say for sure it started after the lift but maybe due to the lift the differential pinion angle to driveshaft and to the transfer case is too high. Maybe I need some pinion shims. But I haven't heard of anything else needed to do this after a 2-3in lift. I'm getting tired of chasing this vibration.

It started completely unexpectedly about a month ago when I was driving around 70kmh while cruising. I would get a few "jerks" of a sputter, then was able to drive a km or 2 before it did it again. I drove to a friends and he got in, and the sputtering episode was over.
Since then, I cannot simulate the way I was driving to make it sputter for any mechanic, but I have been getting sputter on and off the last month.
The one time I got in the truck and started it, put the truck in drive, and it sputtered for a few seconds. I wasnt driving at all this time. This was the only time It sputtered in a stading position.
Here are a few points to maybe, narrow down what happens.
-I am usually driving around 70-90kmh
-I am usually under no loads (not towing, hauling etc).
-My mileage seems to be getting worse.
-this was normally happening not only when the engine was warm, but when it was warm outside and I was driving it for a longer period.
-When I started driving my truck I calculated around 16mpg city. I am currently getting around 13-14. I was on the hiway for around 250 km and got 14mpg. Seems I get better mileage when puttering through the city than when I am on the highway.
I had the truck in to a dealer 2 weeks ago. They did an injector flush, new sparkies, number 5 coil, and took me for $780, saying the problem is fixed.
A few days ago, I was driving on the onramp to the highway accelerating around 90kmh and for around 4-5 seconds I was sputtering and jerking so bad I thought I was done for. The truck finally recovered and again, haven't had any episodes since.
The dealership says their electrician doesn't know what to do, and would need my truck for 4-5 days to try to see the problem for himself. I can only think, as a non-mechanic, that it is something to do with some sensor, possibly a fuel, and/or oxygen sensor.

For the last little while I have been having an issue with the 4wd in my 2006 F-150 with about 93k on the clock. Sometimes it would engage when I switched to 4H/4L and other times it wouldn't. A friend of mine works at a Ford dealership and said it could be the vacuum solenoid on the firewall going bad. So I bought a new one and as I removed the old one, noticed debris in one of the inlets. So I cleaned that out and neither old or new solved the problem. Then I went through ALL of the vacuum lines and found some debris in parts of them....
Cleaned them all out and still nothing. Then I got to thinking it may be the ESOF motor on the transfer case. Checked to make sure there was power to the plug, which there was. Removed the motor and turned switch, and the motor seemed to be working. Reattached the motor and the 4wd would engage/disengage without problem. Pretty much everywhere I went I would check it and it worked fine . Then all of a sudden it didn't . So I took the motor off, turned selector and it worked fine. No issues yesterday at all.
So, I am not sure if it is the motor going bad or not. Could there be a contact problem? I talked to a mechanic this morning and he told me to drive around with it in 4H for a while because more times than not it doesn't get used enough. I'm just not sure what could be going on...am I missing something?

Over the past few months I've noticed that my truck has a very intermittent shudder under mild acceleration. If I accelerated more during the shudder it seemed to disappear until I let off the peddle a little. When it happens the truck doesn't seem to be lacking power and the engine throws no codes. It happened again today right as I had stopped at a red light. I noticed that it was shuddering at idle too. I shut the truck off at the intersection and the shudder was gone once restarted. What it may be?

I just got the spark plugs changed in my Ford F-150 the other day for a misfire problem. Misfire is gone now. But, as I was testing the truck to see how it performed after the spark plug change, I noticed that as it was raising speed with my foot to the mat, the engine felt as if I was slightly letting off the accelerator and then slowly pushing the pedal back to the floor. It loses power as if you're getting ready to slow down for something and then slowly the power comes back and it does it off and on throughout a WOT run from lets say 40-75 MPH.
