Engine shuts down/off without warning after 1-2 hours of runtime in 95-degree weather. Starts right away, but shuts down within 5 minutes. Allow engine to cool for an hour or two, and resume normal operation. Night time driving, no problems. Water temperature gauge, and all other gauges normal. No check engine warning/code. Fuel pump noisy, but otherwise OK.
View 1 RepliesI do not have coolant flow. Changed Waterpump and Thermostat 2 times, hoses, new radiator and even clutch fan. I even cut out thermostat all together just to make sure that wasn't causing any flow problems. I flushed out heater core and hoses.
I'm thinking i have a block in engine not allowing flow. only thing left i can think of... So currently i have water pump removed and my question is: There is 4 open ports, 2 on each side for which the waterpump covers and pumps coolant through. Is the coolant pumped in 2 holes on one side and then comes out other 2 entry ports on other side after flowing through engine block?????
I tried to flush with waterhose, but can only get water to come out on same side of the 2 ports. NOTE: The port are ones square and other circle bore, one on each side. Flushing through square port and water comes out circle port.
I bought my 2005 Chevy Tahoe used in December 2010, with about 2200 engine hours and 54,000 miles. It's been a great car - I love it! In January 2012, when the engine had about 3000 hours, it reset to zero! I went to a dealer, they had no explanation. They contacted GM, who had no explanation either, other that to say it couldn't be done. Since I was left with no way to reset the hour log, I made a note of what I thought was the correct amount of hours. Last month, with about 350 hours showing, it reset again to zero!
I'm at a loss to figure this one out, and don't want to waste my time again with the dealer, or GM. Is it possible cold winter weather has anything to do with the on-board computer malfunctioning? Is it possible the odometer was tampered with, before I bought the car? It runs well, but the only thing I've had to deal with is the transmission, which went out two days before Christmas, at about 87,000 miles. $3500 later, we were back up and running.
Module or cam/crank sensors most likely? How difficult are the sensors to replace if module doesn't fix problem? 120 k mileage.

View 3 RepliesWe recently had a flash flood. No big deal, I was meaning to buy a shot vac anyways.
Anyways, the day after I started using my car, and noticed that my seat belt warning light stayed on, even when I was wearing it. Same went for the "Airbag" light. A couple of days later, the seat belt light start doing what it was supposed to; it would go off once the belt was "clicked". The airbag light has been on for some time. I figured I'd stop in to autozone and see if they couldn't check a code for me, but the nice gal behind the counter said they can only scan CHECK Engine/Service Engine lights. The airbag light, literally just the word "airbag" illuminated in red has been on for about two weeks now.
I imagine the flash food was nice enough to leave me with a shorted wire somewhere, but how to troubleshoot it.
I've had the car for almost 5k miles, no issues. Only performance part on the car is a USP 3" catless down pipe with an O2 spacer. Car performed fine with it. Today I got an APR stage 1 93 octane tune. A few hours into the tune on my way home from work, I went to change lanes and the car hit some type of a wall with the RPMs. At around 3200 RPMs, the car felt like it went into limp mode. Did not let me pass 3200 RPMs. I got off the highway and had to keep the RPMs up because the car died at lights. Pulled into my driveway, plugged in my VCDS and there are absolutely no codes coming up. Nothing. But starting the car the car cranks and I have to give it gas for it I barely start.
View 24 RepliesI have had a problem with my 2009 Chevy Aveo since I purchased it last October 2010. Every once in a while the engine shuts off, not while I'm stopped, but usually after it's been running for 2-3 minutes. It doesn't happen more when it's cold or hot, and not necessarily in the morning or after it's been off for a long time.
It happens only once every few months, but when it does happen it's downright dangerous. Today I was pulling into traffic turning right at a red light and it shut down. I was up to about 15 miles an hour still in the turn, and it feels just like the power steering stopped working. Because it's happened before I knew what to do. If I throw it in to park and turn the key, the engine starts fine and it has never happened twice. In 15 months of owning the car it's probably happened 8 times.
I've brought it into the dealership 4-5 times and they've never been able to replicate the issue. They replaced the spark plugs etc. but it always happened again a few months later. When I went in recently they told me it was the battery and it wasn't covered under my warranty.
They also say because I didn't mention it last time I went in, it must be a new problem. I just didn't mention it because it happens rarely, and they can't find what's wrong, I don't want to seem like a problem customer.
My clock is resetting now and it's a different time every time I start the car so the battery may be an issue... but the engine has never had any trouble starting, not even a hesitation, and the radio stations haven't ever reset.
Can the battery cause a running car to shut off completely, and if so does that mean it had a bad battery when I bought it there used? I can't afford a new battery right now (well as long as it is still starting fine) and frankly I don't believe that's the problem.
Is this a computer issue in the car?
2006 Chevy Silverado 3500 (crew cab dually) with Duramax diesel and Allison transmission. Every time transmission is shifted into Park while the engine is running, the engine will shut off. The engine is able to restart, but this has never happened before.
View 1 RepliesMy 2001 F350 7.3 dually diesel Automatic has been a pretty good truck but recently it has been dying. Engine just randomly shuts off without warning while Driving. Check engine light comes on sometimes. Some of the time it will restart if I cycle the key. Once its running again I can rev the engine up without a sputter but after a few hundred yards down the road it will die again. I noticed driving on the highway when it does it my truck will buck first, then...
If I leave it in drive with the key in the run position when it dies and I'm coasting down the highway the Tach starts jumping around like its trying to restart itself, all on its own. I don't have a scanner.
The last time it died I coasted into my driveway and it wouldn't restart, went back out there 30 minutes later and it fired right up. Its only 40 degrees here if that matters, not hot by any means.
My dad has a 98 Buick La Sabre that will shut off at times. It once shut off as he was turning on the air cond. last summer. Right after it stalled and would not start he attempted to open the windows but they would not work. After a few hours and cooling off it started and the windows worked again. He took it to a shop who said it was the map sensor. They changed it but the problem happened again a few weeks after. The fuel pump has recently been changed along with the fuel filter.
One mechanic suggested it could be the ignition control modular or knock sensor. He recently got a different car so I an going to test drive it for a while. If it shuts down I will test for spark to confirm it is not a fuel problem. I will also try swooping relays to see if that is not the problem. I will be cleaning all the connections I can find with contact cleaner as it can't hurt.
What could be the problem. Could it be a short, a bad wire that once it gets to much of a load on it cuts the engine off?
I have a 1998 Toyota Camry , whenever I start it after its been sitting for 3 or more hours the rpm's shoot up to2,000 and stay there for 3-4 minutes straight, if I hit the gas they don't go down, if I turn my heat on they come down a little bit.
View 3 RepliesIt happened as I was stopped at a traffic light. without warning it just revved up as though I punched the gas pedal, which I didn't. had my foot on the brakes but it still wanted to fly! I dumped it into park and it really howled! I shut off the engine, started it back up and everything was fine! what the heck caused this and what needs fixed?
View 7 RepliesEngine cranks but will not start, it kicks back after cranking over for a couple of times i have replaced the crank sensor it has done this once before it kicked back hard enough to knock a tooth off of the flywheel after replacing flywheel and starter it started fine for three months then it kicked back hard enough to break a starter mounting bolt. i replaced bolt had starter checked and replaced again?
View 6 RepliesAfter filling the gas tank yesterday, as I was on my way to work, the check engine light came on. For the last couple of days the temperatures outside have reached 118 degrees. I have checked the oil and coolant and have resealed the gas cap as well, yet the light still remains. The research I have done leads me to believe the problem may be the catalytic converter, but I'm wondering if there is any further troubleshooting I can do without heading to a mechanic.
View 7 RepliesThe last time I had my car serviced, the mechanic told me that while it wasn't a pressing issue, my power steering pump was starting to go. Lo and behold, it's that time. I started to notice that while idling I hear a dry, raspy sound coming from the engine. I left the car on, opened the hood, and it's definitely something spun by the belt. I'm 99% sure it's the power steering pump, so I'm going to replace it. Furthermore, do I need to "bleed" the lines? How does one go about doing that, anyhow?
View 13 RepliesI have a 1998 chevy blazer and I cant get it to start. I removed the starter and turned the key and can see the starter popping out and spinning, but when I put it back into the flywheel all I get is clicking noise(like if the battery is dead) I had it on jumper cables so I don't think its the battery?
View 12 RepliesMy 98 chevy luminas service engine light came on after I got gas. I put vaseline around the threads to seal it and the light went out for 2 days and then came on again. I bought a new cap and the same thing happened, two days light out than back on. I took the car to Autozone and did a diagnostics test which came back with error message P0341, then took it a mechanic who ran his on diagnostics on it and he says the camshaft sensor needs changed. It is a semi expensive job for an older car and I want to be sure that that is the problem, plus the gas cap thing has me confused.
View 7 RepliesI keep good maintenance for my car. Just had the 45,000 mile major tune up also. However, the engine overheating light came on the other day - said I should idle until it cooled down. I was just about to park, so I did that and left to do some shopping. When I came back and started the drive home the light came on again and indicated I should stop and turn the engine off. I drove two more blocks and put the car in the garage. I noticed what I thought was some leakage on the garage floor also. Next AM, I had it towed to the dealership since I'd checked the coolant dipstick and it looked EMPTY!. Dealership tested it out and could find nothing wrong - no leaks, no computer faults either. They sent me on my way and neither warning light has come on since. I've kept an eye on the engine temperature gauge and it hovers around 200F - mid range on the gauge. No further problems. Funny thing is, now my A/C seems to operate better!
View 10 RepliesI have a 1998 chevy 3500 2wd pickup with a 454 engine. The check engine light is on. I have had the codes read and they were for a MAF and MAP sensors. I have replaced both. The check engine light is still on saying that I have a bad MAF sensor. I replaced it again. The check engine light still is on. What else should I look at to fix this problem??
View 19 RepliesI have issues with engine starting when cold outside or after rain. This only happens when engine is cold and has not been started for a day or 2. Distributor cap does not have any condensation inside but does seem to corrode on contact points. Engine turns over fine, has fuel and spark. When this happens engine will not fire and after awhile it will start to fire and lock up when it fires then continue cranking. After repeated attempts it will start and run fine, can be shut off and start right back up with out any issues. It could take a few tries to a few hours of trying before running though. I'm leaning toward a distributor or timing issue. Am I on the right track? 98 Suburban K1500 5.7L ....
