Question about 2002 GMC Envoy

1 Answer

Throtle Body? My car is having trouble starting not every time but more and more often. Two weeks ago I was unable to accelerate for a few minutes but re-started the car and it was fine. I took it to Kia two weeks ago when it had the acceleration problem and they replaced the fuel throtle sensor and sent me on my way. Now that I'm having problems starting it they have said it's the throtle body. I was assuming the starter or atlernator because it almost sounded like the battery was dying. Does this make sense? I'm not a mechanic but I just didn't think those parts could cause such a problem!

It takes 7 minute to recharge a battery from a standard start(about 3 seconds) if you are cranking longer than that then yes the wear is occuring to the starter,alternator and battery.
It could be a throttle body leaking or a fuel pressure regulator.

Engine light says Reduce power


This is most likely related to one or both accelerator pedal sensors. Communication between the two is not sufficient, causing the reduced power indicator light. One or both sensors will need to be tested and/or replaced. You can check the connections at the throttle and at the top of the accelerator pedal for a loose or corroded connection.

when my cars do this I check the fuel supply first.....should be a small filter near the throttle body somewhere that could be prob. then check electric/fuel related items. there are several different items with these symptons, nearly always related to fuel....go to a good websight like autozone repair guide for help....also a haynes or chilton manual available at parts houses will save you lots of bucks----i never take my cars to a garage...this is general info, but i hope it has helped...

1994 Ford Probe GT - Uncontrollable Revving


ok, this is simple to do but I would get the Chilton for your car so you can have pictures of what to do. You can get the chilton at the parts store, or the library. It sounds like a throtle body sensor or the throtle body itself, but could also be your air idle control sensor. go down and buy some mass air flow sensor cleaner and a BIG can of carb cleaner. First clean the mass air flow sensor neer the air filter. then remove the throtle body it is held in by 4 botls and you may need a new gasket, NO GASKET GLUE. Now take that big old can of carb cleaner and start cleaning in and out. also down into manifold. clean everything. Now put it back together, remember 4 bolts and no gasket glue. if the problem continues replace the throtle body sensor. and then the idle air intake. It will be cheaper to take it into the part store and have them put it on the computer. They can often tell you what sensor it is ahead of all this but don't let this stop you from cleaning out the throtle body, it will make your car run better and longer.

Hello, and thanks for choosing FixYa for assistance.

Before I would consider anything else, I would take your vehicle to a competant repair facility and get the automatic transmission fluid completely flushed. This may be all that your problem is.
