My Car is jacked up please help!!!?

Question

I drive a 2001 GMC Yukon, Automatic with about 87,000 miles on it. I have had 2 main problems with it as of late. I will be making a hard left or right turn and it will stall on me, and now that problem has elevated to stalling sometimes when I am going straight but this only happens at low speeds.Also I will stop at a red light or a stop sign and I can hear and feel the engine rev up slightly and then go down.It kind of causes the whole truck to vibrate and it's very noticeable. It does it alot, almost every time. The RPM gauge also moves up and down with the reving of the engine,Anyone have any clue of whats happening?

Answer 1

Take it to the shop and have them put it on the computer. This is much cheaper than hit-or-miss parts replacement. The computer is telling the engine to speed up or slow down based on information it receives from any number of sensors all over the vehicle. One of these may be bad, but you won't know which one until someone reads the computer.

Answer 2

I have never been car-jacked, but I did have a car stolen about fourteen years ago. It was very traumatic for me. Regarding carjackings- It's better to just let the attacker have your keys if they have a weapon and can harm you. Carry a can of mace with you. You can get a small one little enough to carry on your keychain. You probably won't ever need it, but it's better to have it and not need it than need it and not have it. When driving, especially at night, keep your doors locked. In fact, always keep the doors locked no matter what. Never, ever leave the car running and walk away, even for five seconds. Thieves are desperate, and can steal a car quickly. Always keep the doors locked. When driving, always keep a small bit of distance between your vehicle and the one in front of you. Give yourself enough space to escape, because sometimes, carjackers will have a car that pulls in front of you, then one is behind, and they can box you in. By keeping a safe distance behind the car in front of you (at traffic stops, etc), you give yourself a better escape route. Good luck! God bless!

first, get a tune up if u haven't had one in a long time, if truck has been tuned not to long ago , i would look at idle control / sensor. and if that is ok then it is some other sensor. the reason the truck revs up like that is because the computer is trying to make changes in the running of the engine to keep it running, it is trying to fight the problem that is causing all of this , that's why it revs motor, good luck

Answer 4

Before you take it to a shop, check for vacuum leaks around the intake manifold. More than likely a vacuum line came off "T" connector behind the throttle body.
Listen for a high pitched sucking noise around the intake.

The other option is a stuck EGR valve causing the exhaust gasses to recycle thru the engine all the time. Instead of only durring acceleration.

Answer 5

fuel filter.

Blockage, or dirt in the fuel filter can cause inconsistencies in rpm and is most noticeable when driving slower (as in turns) or idle. If neglected vehicle will quit altogether.

Answer 6

first you need to have it scanned for any codes, take it to a mechanic or Auto Zone will do it for free. we fixed a car last week w/ similiar symptoms we changed an oxygen sensor, Idle air control valve, and the fuel filter. its running good now.

Answer 7

it could be a fuel delivery problem. either your filter is plugged or the fuel pump is starting to go. take it to a reputable mechanic and have it checked out for sure before you do anything.

Answer 8

Our friend just found out he has to have 12,000 dollars done to get his Yukon straightened out something to do with the engine. Might as well sell what you got and get something with less problems!!

Answer 9

Sounds like your fuel filter, maybe your transmition. Good luck
