Chevrolet - Tahoe :: 1998 - Very High Engine Rpm All Of A Sudden
It 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 RepliesChevrolet - Tahoe :: 2003 - Reduced Engine Power Error
From time to time, my Tahoe gives me the "Reduced Engine Power" error, and I lose acceleration capabilities and have to pull over. After a min or 2, I can go again, but the check engine light stays on. With no rhyme or reason, the light will be on or off on the next start up. The problem may or may not happen during a short ride or may happen quite often. I have replaced the Accelerator Pedal sensor, so that is not the problem, I'm assuming.
I've been told that it is the Throttle Body that needs to be replaced, but no mechanic can confirm. They just want to replace it and the pedal. I would really like to keep this truck for a couple more years. Other than this problem, the Tahoe has been pretty good to me. Here are the codes that have been read: P1125, 1516, 2120, 2125 ....
Chevrolet - Tahoe :: 2005 - Total Engine Hours Has Reset To Zero Again?
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.
Starting - Chevrolet - Tahoe :: 2001 - Clicking Noise Right Before When Engine Trying To Catch
I have a 2001 Chevy Tahoe, and for the past couple of years, I have been having an incredibly frustrating issue with my car. When I go to turn the key, it sounds as if it is about to turn on (ie the engine is about to turn over and it sounds normal) then right before it catches, it will start clicking, the noise sounds like the battery is dead. When it first started happening, I called AAA, however by the time they reached me, the car had started again. Now when it occurs, I wait 10-15 minutes and it will start- every time. I have had it in to 4-5 different car repair shops, however no one can seem to figure out what it is. I have had the battery replaced, and several other things altered, etc, however nothing seems to fix the problem. I am not sure where to go from here, I was informed to check the fuel pump and/or filter yesterday- it happened twice on me yesterday as well.
View 3 RepliesChevrolet - Tahoe :: 2007 - Service Four Wheel Drive Light Displaying On Panel
Our 2007 Chevy Tahoe 4 X 4 recently displayed a "Service Four Wheel Drive" panel light a couple of days ago (upon ignition on a sunny, dry day). The light had been steady which, when we read the owners manual, indicates a problem but no immediate service required. One of the possible solutions was to remove and close the gas cap in case it had been incorrectly closed during the last gas-up. That did not work. Yesterday, during a snow storm, I tried using the 4WD. The dial would move to the different settings, but no 4WD activated and no light illuminated indicating which gear it was in (2WD, Auto, 4H, 4L). We checked the fuse for the 4WD but it is OK.
View 5 RepliesChevrolet - Tahoe :: 2003 - Reduced Engine Power Message / Speed Losing
I have a 2003 Tahoe that I love but is driving me crazy with a "Reduced Engine Power" message. I am driving along and suddenly it dings at me, the message center says "reduced engine power" and I am losing speed. It goes into a "limp mode" in which I cannot accelerate, it cannot pull itself up a hill, and the engine misses badly. I can pull over, shut it off for a couple of minutes and then start it up and run again just fine until it decides to do it again.
There seems to be no rhyme or reason, one day it did it 4 times w/n the first 20 miles, then ran 100 miles w/o doing it at all. I recently took it on a trip that normally takes me 1 1/2 hours, it took 2 1/4 hrs that day because I had to pull over so many times. I was having to stop every 3-4 miles by the time I got there. My usual mechanic has completely given up, told me to trade it. I have had it to another mechanic for over a month now, 3 times he has thought it was fixed, but it wasn't. One time, I didn't even make it the 5 miles to my house before it acted up again.
One other note on this: this past trip I made, I left early in the morning and my lights were flickering high/low. . . this went on for several miles. Finally my lights quit flickering, then I lost engine power, pulled over, shut it off. When I started it back up, the lights started flickering again. The cycle seemed to continue, once the lights would settle, the engine would lose power. I took it to a parts store and had the battery and alternator checked. They said both were fine. (Had never noticed the light thing before, but I can't think of a recent trip after dark.) How I can pass along to my mechanic?
Engines - Chevrolet - Tahoe :: 2002 - Clicking / Ticking Noise Appears To Be Coming From Engine Area
2002 Chevy Tahoe Z71 ... When I first turn my car on in the morning (or after an extended period of time - i.e. the car has completely cooled down) it makes a clicking / ticking noise that appears to be coming from the engine area. It lasts approximately 10 - 12 seconds and then simply goes away. This happens consistently. I recently had it serviced end-to-end: belts, plugs, total tune-up etc.

Click and Clack... When it wouldn't start one day (away from home) he had to keep going back to where it was to try to figure out what was wrong. He came up with a few different diagnoses but came to the conclusion it was the fuel injector inside the gas tank and went online to order one. Once it finally got towed back home, he had a chance to really get a good look and found that all those wires had been chewed and eaten. They're too short to splice back together.

Chevrolet - Tahoe :: ABS / Brake Lights On For A While Then Go Off Intermittently

View 2 RepliesChevrolet - Tahoe :: 1997 - Simply Will Not Start Every Once In A While
I have a 97 Tahoe that I love! The problem is that, every once in awhile, it simply won't start. Won't start, won't crank, won't do anything. I turn the key and nothing happens, similar to having the truck in gear and trying to start it. The REALLY frustrating thing is, when I take it to the mechanic, they can never recreate the problem. This last time, the mechanic had it for a couple of weeks, couldn't ever get it to not start. I had it for a week, and it stranded me an hour and a half from home.

98 Tahoe ac giving me warm air once again. 5 weeks ago had it in the garage. they found a leaking schrader valve and re-charged and added dye. checked it and didn't see anymore leaks. they said keep an eye on it and if it stops cooling bring it back. well.........it's going back! it's blowing warm air even though I hear the compressor kick on. what else could be giving me problems? of course i'll take it back but i'm just wondering if a switch failed this time or what the heck is happening. I was surprised to hear the compressor running with warm air.

I have a 2004 Chevrolet Tahoe 2WD with the 5.3L V8. Tahoe has 134K. At about 125K miles, I replaced air filter with a K&N, new OEM spark plugs and spark plug wires. The Tahoe has been running great and was getting normal mpg until recently. 15mpg in town and 17mpg on the road is what I normally get. The last 3 fill ups my mpg has been below 13.5mpg. Car still runs great but at 13mpg it's starting to hurt a little financially. Weather here in NC has been normal, my driving conditions or habits have not changed, etc. What could be causing my mpg to drop by so much while the suv still rides smooth and straight?

My 95 Tahoe smokes bad on startup (coolant) and a little (oil) on accelerating from zero. There is also a large internal coolant leak. I just replaced the intake manifold gasket as it was the easier fix; didn't do anything. Does this mean it is definitely a head gasket? Anything I can do in the meantime until I have time to pull the heads?

2004 Tahoe that started with no heat in rear. Checked all hoses and they get hot all the way to back. Replaced rear blend door actuator and worked for a little while. Tonight, took a 90 minute trip and it blew ice cold until suddenly it started blowing heat 45 minutes into trip but then went back to cold after about 10 minutes. Actuator is electric not vacuum. Could it be in the controls where you adjust the temp?
