Gmc - Envoyxl :: Engine Will Rev High For Few Minutes While Driving And Then It Stops And Returns To Normal
Feb 4, 2014
We have a 2003 GMC Envoy. Normally upon starting the car, the engine will rev high for a few minutes while driving and then it stops and returns to normal. However, this morning I was driving the car and it was revving high continuously. Every time I started from a stop at a light, it would rev up to 2 RPM's and continue higher while the car was just sluggish. I would let off of the gas pedal and it would drop back down and slowly shift but then it would return to making a loud revving sound as I stepped on the gas pedal. There are no lights lite up on the dashboard and everything looks normal except for the loud revving sound and the car being sluggish because of the high revving.

I have a '12 Focus and for no apparent reason the A/C will turn off and warm air enters the car for 1-3 minutes and then returns to normal cold A/C air. It doesn't matter if it's on "max A/C" which will circulate the air inside the car or just the coldest setting on the A/C, high fan, low fan, it just happens. What usually happens is that I'm driving 40 or 45, then have to slow down (stoplight, etc.) and speed up again, during the slow down is when the A/C turns off and warm air enters the car. As soon as I'm driving 45 again for a minute it usually kicks back to cold air. OR, while driving on the freeway at 60 - 70mph after about 15-20 minutes it all of a sudden stops cooling and I get warm air in the car. It's been checked by 2 different dealers already 4 times and they never found anything wrong with the A/C System. It did have an actual leak a few weeks ago and that got repaired but it still has this mysterious behavior.

I have a 99 4.2L 5 speed reg. cab swb. It recently started idling high (which returns to normal at a stop after 3-5 seconds). While in neutral and in motion (coasting) the idle is around 1500-2k (idle=no throttle input from me). The first time it did this it took a while to start (7-10 seconds) and smoked like you wouldnt believe for about ten seconds. Smoke cleared, eyes returned to normal size, heart rate returned to "normal", but the high idle remains. Drives me nuts. No CEL, no codes, just a fat bald man scratching his head and a little nervousness.

2002 B5 1.8T, 54,000 miles. When you turn on the A/C it blows hot air. After 10 or 15 minutes of driving it turns icy cold then sometimes returns to hot air.

2009 V6 Auto. The car runs perfectly, the cel and traction lights have been on for a year. I bought a scangague that reads and resets them. The code returns within 10 minutes of driving after being cleared. The code refers to 'air bleed circuit'. Fuel economy is about the same as our other V6 Camry of the same model. Any clues?

I'm driving a 2000 F150 with the Triton V8 5.4L.
My check engine light came on the other night while heading home. I went to Auto Zone and had them scan it and it came back with the P0125 error code.
My guess is that the thermostat is faulty because my heater is blowing lukewarm air after about 20-30 minutes of normal driving and I would expect the air to be much warmer so I'm thinking that the engine is not getting up to normal operating temperature.
I understand that this can be bad for fuel economy and such, but my question is it safe to drive?
I had planned on hunting up in the hills tomorrow all day and just want to know if this could cause any damage?
Here's a picture of what my cluster looks like after running for about 30 minutes.

I've got a 2004 Honda Civic with the 1.7L engine. I drive for about five miles and the engine stops suddenly but only for a half-second then runs again like normal. At the same time, there is a click - click behind my glove box. Relays I'm almost sure. And the way it happens is :click > engine stopsclick > engine continues running normally. Used to happen only on hot days, now it does when it's cool out once the engine is warmed up.
After it does this over and over about 6 times the Check Engine Light comes on and it doesn't jerk so hard, but stumbles kinda mildly, but all the time - though usually by this time I have gotten off the road and am swearing loudly.The Honda mechanics are running the clock RIGHT NOW and it may cost me a fortune - Also, there is no error code showing. Nothing. And I also replaced some relays, to no avail, because I read about cracked solder problems someplace...

My friend's Accent LC 1.3L won't start from time to time. This never happens on cold start, this is always the situation after warm engine stops and needs to be run again after 5-15 minutes. When you try to turn on the car then, starter is rolling the engine but nothing happens (Yellow key light on dashboard is on, so there is no problem with a key code). Then he wait for a few minutes and car starts like it nothing happens. I suspect the crankshaft sensor.

I've got a 2006 f250 with 160,000 miles, trans was rebuilt by previous owner about 10,000 miles ago. The tow/haul light started blinking yesterday, only blinks for first couple of minutes of driving and then stops. Service engine light popped on today as well. Won't have access to a code reader until tomorrow, but looking for some preliminary info...

I seem to have this high pitched whistling noise as I am driving at normal speeds (starts at ~40-45 mph). It seems to coming from my rear drivers side, but I'm not entirely sure. My R has about 78,xxx miles and I haven't done this 80k....

I have a 2002 GMC Envoy XL. 120,000 miles. It has been a great car. BUT for over a year the engine fan stays on all the time. REally a big noise. A year ago I took it to the dealer and a local mechanic. Both say that it is relatively safe to drive it like it is.The blue book on the car is about $3500. We don't want to spend $1,000 on such an old car but it is very loud and obnoxious to drive it.

After driving for 30 minutes on the freeway, my Sonoma develops a high freq vibration that seems to increase after it starts. lessens a little as I slow, but does not go away until after the car has been parked for a while, but not as noticeable under about 30.. I have experienced this the last three days on my commute to and from work. Did have the breaks checked. I did have a clunk sound when i released the brakes at a stop, but that went away after the first brake check where they did not find anything, but just cleaned out the dust and readjusted. The vibe is pretty strong and makes me nervous to drive.

When I drive 30 min the oil temp raises up to 110c and the coolant raises up to the redzone. And when I stop for a red light my front window get fogged all the way I can see barely anything.
Coolant is filled everything is okay. Only sometimes its really low or when the engine almost hit the redzone its a bit empty. No leaks nothing. Now my vds says 2 errors :
Fan 1 blocked
Fan 2 blocked
When the engine is warm the fan doesn't turn on none of them does, today at the local shop the worker did something and they started working but it doesn't turn on now its off and stays off is the fan switch dead? Is it really the the not working that's causing so much heat.

I need diagnosing a problem on my 2002 Hyundai Accent LC. When I accelerate with the aircon on the engine stops accelerating at high RPM and when I accelerate from a stand still the engine hesitates and jerks! I don't understand what the problem may be coz it works perfectly after a cold start but after it warms it starts doing that.

I start the car, with AC on, radiator fan starts and within a few minutes the engine radiator fan stops working, idles rough since the AC compressor pump keeps cycling on and off and engine starts to overheat. After shutting down I check the engine cooling fan fuse and it sure enough is blown.
How do I determine as to where the short is? Is the short in the wiring somewhere or can the actual motor short out?

Idles really high at startup until the engine gets to normal operating temperature and falls back to normal. Takes 10-15 minutes. I recently de-greased the engine and think I may have fouled a sensor...though the check engine light is NOT on. I'm afraid if I keep this the way it is it will cause damage to the engine.

Shown on a Corolla, but would work even better on a Prius because of the way the engine starts and stops while driving.

Recently my wife took her car to work. While driving on the highway the car all of a sudden quit responding to pushing on the gas. As if the pedal had no affect at all. The electrical was still in tact as my wife pulled off to the side of the road and turned the car off. Before I could reach her to pick her up she had started it again and it started right up no hesitation at all. Upon dropping her off at work I came back and it started right away and I drove it to her work and she then drove it home at the end of the day with not problems. It sat in our garage for a few days and I decided to take it out to see what happens for myself. I drove it for a full day stated right up every time and it wasn't until the second day I drove it around that it did the same thing to me. Gas pedal had not response. All electrical seemed operational, still had power steering and the dash was lit. I pulled over then waited a few minutes and it fired right up and I was on my way. Wondered if its the fuel pump and how I could test that out. As I said is starts right up every time with no hesitation. Also I have fuel pressure tested it and it shows a 60 the during idle.

I own a 1999 Park Avenue Ultra. Recently it's developed a problem where the engine just stops when I'm driving. It happens at all speeds--on the highway, on local roads, in parking lots, or just idling. Starting up the car after it stalls is not problem; it always starts right up. The car stalls at least once a day after it's all warmed up. Additional stalls can occur, but there is no quantifiable interval between additional stalls. This car has spent most of its 148,000 miles in the upper Midwest. This past winter I drove to car to Arizona, and that's when the stalling started. One mechanic looked at the car, but couldn't find anything wrong and couldn't get it to stall when he took it out for an extended drive. What the problem might be?

I'm coming home from just running errands around town, got the stereo on pretty loud, normal driving, good weather, and the engine just shuts off. Lights are still on, regular brightness, everything electrical working, but battery light and EPC light are on and the engine won't restart. It'll turn and "click" like it's about to start, but just the starter turns over.
Fast forward 5 minutes (no activity in the interim), and it starts up first try. Battery light is now off but EPC light is still on. This happened about 2 blocks from home, so I gently take it home. 1 block away, the EPC light goes off. I let it idle for a minute and everything now seems normal. I shut it off and so here we are.
