It had no spark when I put a spark tester on, a few minutes later it started and runs fine. This has happened several months ago. Is their a way to test the spark control module.
View 3 RepliesI have an ambient temp switch connected to the vac port on my throttle emissions control solenoid for my 2150 carburetor. It's a 78 F-150 with a 5.0L 302, automatic 2WD. Would a bad ambient temp switch screw up my idle? I've disconnected the vac hose and it won't idle at all, and it does the same thing when I disconnect the two wires from the ambient temp switch. If I leave everything alone, I can get the idle down to around 1800rpm, but any lower than that and it stalls.
Is it possible to swap out this throttle emissions control solenoid with another type? I've looked everywhere and can't find an exact replacement, and I have no instructions on how to tune it.
I've got a 89 ford Thunderbird that I've replaced coil and all other things i can think of but still no spark. I pulled the plug which connects to the coil pack and tested the positive side of plug and not hot with key on then i went to back side of plug and got a hot.
View 1 RepliesI was taking out my plugs 2 of them were soaked with gas and oil and 1 of the other ones just spins. what do I do? The car is a 1995 tbird 133000 miles the car has been sitting for a year and I couldn't get it to start that's why I am pulling the plugs the car ran fine when it was parked....
View 7 RepliesI get an intermittent spike in RPM with a lurch in the engine when I'm holding anywhere from 1500-1700 RPM. I say it's intermittent because it might happen three or four times over the span of a few seconds, and then nothing for a minute or two. I don't think it's the transmission because it doesn't happen during shifting, and I can duplicate the problem in D, N, and P. What could be causing the problem?
1991 Ford Thunderbird SC, 3.8L 6 cyl with supercharger, 4 speed automatic transmission172,000 miles
Engine is a 69 390, fresh rebuild by the PO... Aluminum intake manifold and new Edelbrock 4bbl Drop in Crane ignition.
Runs great... Except when its warm out, or even on cold days when its warmed up after a substantial drive..
AT that point here is what happens: No issue until I shut it off then it diesels badly, THEN.. When I restart it will not idle, dies.. If I keep my foot on the accelerator it will keep running, but not well.. If I let it run for a good while, 5-10 mins, it smooths out... Consistently acts like this .. Again.. Not when the engine is cold, and not on a cold day until it really warms up..
I suspected a vacuum leak? Replaced any suspicious vac tubing.. Cant get to the AT modulator easily, have not checked it yet?? Also suspect the intake manifold??
Got Tiguan 2011 46000 miles on it. Just serviced intermittent no start and occasional stall after start.
Dealer replaced High pressure fuel pump and fuel pump control module. So far so good.
Seams like common issue.
What's going on with my '93 240. When I first go out to start my car in the morning, it starts up fine. After that, however, is when the trouble begins. If it's hot out, or if I've driven the car that day, there's a 50% I'll have trouble keeping the engine running. The engine will run rich, and chugs on startup, eventually stalling out after a few revolutions. During this time, the engine revs low, don't have a tac so I can't say how low, but definitely below idle.
If hold the accelerator to increase the RPM, the engine will run fine, but once I let off the gas, chances are it will stall out again. Eventually, after doing this a few times, something seems to catch the car as it begins to stall again, as in, just before the car is about to stall, the idle speed kicks up to normal. After that, the car runs fine.
I've had a code for the MAF for a long time. I tested the resistance across the meter, and it indicates the wire is still good. Even at that, I've replaced the MAF, but nothing has changed. Still have the same problem. What could be causing this?
I purchased my 2013 SF 2.0 Turbo SE in August 2013. Up until then, I was a long time Toyota owner. I've very satisfied with the SF, except I've been having an intermittent issue since I bought the vehicle.
Maybe 3-4 times a month, out of the blue, when I making a left hand turn, there is a hesitation when I press the accelerator. The hesitation lasts for about a second or so, but when there's traffic coming at you while you're making the left turn, it can be quite scary and the second feels like forever!
The hesitation feels like there is absolutely no power and the engine will stall. It never does. I've had it back to the dealer/garage for diagnostics several times but they can't seem to find anything wrong. And they keep charging me for the diagnostics! This occurs in ECO mode and non-ECO mode.
My 1996 Dodge Grand Caravan has developed a curious problem. It intermittently stalls, sometimes when slowing down, sometimes when going up an incline, sometimes on straightaways. Once stalled, it often won't start again until it has sat for 20-30 minutes. Then it starts right back up again and drives perfectly normally until the next time that it stalls-which can be days or hours. The problem is definitely getting worse--six times today. Warmer temperatures seem to exacerbate the problem. Again, the engine runs very smoothly up to the point of the stall. My mechanic was unable to replicate the problem and his diagnostics showed everything to be normal.
View 5 RepliesI have a 06 Passat with a V6 with 80K on it. Recently I have been getting intermittent stalling at start up, only when the engine is warm(but once on a really hot day). The car will rev slightly and stall. After several attempts, it will start, and then it runs fine. VW service said no error codes and didn't offer much more.
View 10 RepliesI got a 1986 chevy g20 conversion van and I am having a problem with it once in a while it will stall out after putting it into gear it does not do this a lot but it does happen also smells like its running rich and until it warms up while the van is in park you can hear a intermittent click sound goes click click............................click...click no real rhythm just kinda does it then stops when in any gear besides park friend said it could be a small backfire. The engine is a 350 V8 4 barrel carbed.
View 1 Replies330,000 km on car. I drove 45 minutes when battery light came on on and car engine stalled when making a left turn (fuel light had just come on too but not empty) and restarted on own, drove 10 minutes and it stalled again, so I pulled over and restarted. Drove 45 minutes home. No issues since. Shop says 10 year old battery and alternator are testing fine, though they suggest replacing alternator as it may be going. Could there be other electrical issue since the issue is more intermittent? Car would not stall immediately if alternator failing I would think - should run on battery for a bit and not restart. Drive maybe 400km per month and it sits for 10 days at a time.
View 4 RepliesMy wife drove the car to work, and it ran good. She got a check engine light, but it was not on when I got home from work. I started the car and it idled fine for a couple of minutes and then it stalled. I check the codes and there was nothing locked in. There was a pending coding P0321. I am not sure what a pending code is, but I assume not enough to trigger the check engine light.
After work each night this week I tried troubleshooting but I have not gotten anything accomplished. Each night the car would start fine but if I turned it off it would not start until many tries if at all. It turns over strong but won't start. I drove it around the neighborhood today and it stalled and wouldn't restart.
The fuel pump primes. When the car won't start the fuel pump relay clicks constantly. Is this normal? I replaced the fuel filter because it has been 50k miles. Is the crank shaft sensor the problem? I hate to throw money at parts that aren't the problem when I can't get a code to trip the check engine light.
At times my windshield wipers stall halfway up my windshield or move really slowly. Other times absolutely fine, I already checked both battery terminals and niether were the issue. What's the best way to get to the wiper motor to check the connections. Or does it sound like a ground strap issue elsewhere on the car.
View 5 RepliesI have a 2013 Golf TDI with 2070 miles on it. For around 2-3 weeks, I've noticed that it intermittently will idle rough, shakes, etc, as if it is about to stall out, but stays running and drives normal. I figured it was a typical Diesel thing and wasn't too worried about it. However, today, this happened, and I got an engine light. Yikes! I made an appointment for it but need to wait till after the 4th for it to be looked at. What's up here? Is it a regen cycle? Timing issues? Am I doomed with my Golf TDI?
View 8 RepliesI've been having an intermittent stall-out problem with my 2003 F250 5.4L (160k miles). The truck has been retired from DD to farm duty, hauling, and towing only. Over the past 9 months, the truck has stalled-out on me 3x while driving. I will be driving along sometimes at highway speed, sometime slower, and everything will die: no PS, lights go on all over the dashboard. It will not restart right away. I have to wait at least 20-30min to restart it and then everything is fine for several weeks and hundreds of miles.
There are no codes and I have been unable for reproduce it/cause it to happen purposely. My mechanic has changed the Crankshaft Position Sensor, and checked the fuel rail pressures. I also checked all the harnesses and fuses, cleaned the battery terminals, looked for vacuum leaks, and gave it a good look-over. The following are new: battery, IAC valve, fuel filter. After searching the forum I also pulled the fuse box and examined the integral fuel pump relay: it and the board looked perfect, no bulges, cracks, discoloration, etc.
My mechanic thinks this is more likely an ignition problem than a fuel delivery problem.
The problem began with intermittent stalling and now the Jeep will not start at all (no spark). I have had the cap, rotor, primary ignition coil, crank sensor, cam position sensor and PCM replaced without any luck. The repair bills have been brutal. The garage has given up.
View 8 RepliesOne morning my 09' Elantra didn't start. It sounded like it was only the starter running. I checked the spark and there wasn't any. I checked the fuel injector pulse and got nothing. Occasionally I could get it to start just by trying a bunch of times but never more then once in a row (or day for that matter).
I decided to replace the Crankshaft Positioning Sensor. The first time it took a bit but started up and ran nicely, till i turned it off. Now I'm back to a no start car and again with no spark or fuel injector pulse. It does feel like it's trying to turn over just a little bit now that i replaced the sensor.
1999 F250 SD Ex 4x4 V10 has been intermittently not starting, both cold and warm, began last fall but only happened once a month or so or longer. Would then start after trying again either right away or after waiting a bit. Now it is doing it on a regular basis. Sometimes it will start right away, sometimes won't but if you keep trying or wait awhile it starts, sometimes using the extra key will start it right away after the first one didn't, sometimes neither one. It does not try to turn over, make any noises, no warning lights flashing, just won't start.
Now also on two occasions within the past week, it just stopped while driving. Radio, dash lights, etc., stayed on. I got it to the side of the road with the little power steering left where it started up again right away.
No codes showed up. First mechanic couldn't find anything obvious or replicate problem. Changed air and fuel filters (fuel filter really needed changed), plugs. Got truck back and it wouldn't start next morning. He checked it again and got a code related to ignition, tried the spare key and it started up. Truck back home, next day same problem.
Mechanic 2 checked, no codes, kept several days but, of course, couldn't replicate problem. I'm not even sure what all they checked, used to be an excellent repair place but now they seem to only really on diagnostics and throw up their hands, very disappointing. Replaced solenoid and starter last year myself. Otherwise, have had no problems until this.
I recently was given a 96 Toyota Celica 1.8L Auto 7AFE and I have been trying to troubleshoot some problems.
It started a year ago when my brother drove it to work and then after work it would not start back up. It sat for a while and now its mine. Problem is I was not getting any spark at all a while back when we tested it. I thought maybe the distributor. The other day it happened to just randomly start after a year of not starting. It made a small pop in the cylinder then boom ran just great until it warmed up and proceeded to shut down, would not restart. Checked the spark and it was very weak (yellow) and just seemed to be a slow spark, not firing as fast as I would think. Today I put a new distributor with a new cap and rotor in and boom she fires up immediately. Let it warm up fully shut it down, restarts fine, shut it down again and now it will not restart. Last time I tested fuel was fine, seems as if I am getting an intermittent spark and usually starts when it cools off.
Not sure what to do now, where to look. The wires seem ok with no corrosion but I have only worked on the 2.2L and I am lost!
