SOURCE: Vibration when in gear, and stalling.

The problem is the torque converter solenoid. I had it happen on my 94 Cavalier a few years back and was a cheap fix at the local car mechanic. What happens is the transmission warms up and hits a certain speed where the solenoid engages, but then it sticks and won't disengage until it cools down sufficiently. When it sticks, it causes the car to shake when slowing down and will snub out the engine if you come to a stop.

Check for vacuum leaks. Also try cleaning the ISV.

I would start with cleaning the throttle bore and plate. Then clean the Idle Air Control valve, IAC, as this is the device that controls idle speed. Use a can of spray carb cleaner and an old toothbrush. Trouble with the IAC would make sense if you can keep the engine going by holding down the gas pedal a bit.
Use the carb cleaner to check for vacuum leaks at hose connections and elbows. run engine and spray short bursts at hoses and listen for idle speed changes.
And lastly if problem is still there check MAP sensor.

1994 Chevy Camaro, 6 Cylinder, stalling problem


Try cleaning the throttle body and the idle speed control valve, they get full of sludge and this causes stalling. Use a product called CRC Throttle valve cleaner on both parts, DO NOT USE CARB CLEANER IT WILL RUIN THE PARTS.

1988 Suburban with 5.7 TBI runs fine until warms up. Goes to fast idle and when it comes off fast idles won't start back until cools down.


Lets start at the beginning. Is the check engine light on ?
You have an idle air control valve which could be sticking open or shorted to ground. You should be able to unplug it to test. There also could be a gasket or hose that is opening up and causing a huge vac leak.

I have a 2002 chevy silverado, 4.8l. i was driving it yesterday, and i came to a stop light, i stopped then the light turned green and i tried to start going, i pushed on the gas and it felt like it wasent...


First of all, If you recently bought gas from a place you've never been to before, drain out the old gas, and put in a fresh tank from somewhere you trust. You may have water in the tank. After that, if that doesn't solve the problem, or you trust the place you bought from, go ahead and check all your external gas filters. If that doesn't solve it, I think that's when you're right: It's either the fuel pump, or the fuel filter, and in modern vehicles, both are in the gas tank, and both are very difficult to get at.

We have a 2003 chevy suburban 5.3 vortec it dies when warmed up


Sounds like either Air mass sensor, Air mass meter or finally the EGR valve this is the exhaust gas recycler I would say that is the fault when they start to go this is what they do until finally the car will barely move.

Also I would check all your air pipes for leaks make sure there is no rips or tears in the pipes, The car will drive fine like you say until you ease of the gas to a stop position it **** in to much air and kills the engine. Air faults are cheaper so look there first.

Hope this helps

Truck runs great but cuts out and starts back up five to ten mins later. I replaced the fuel pump and wireing in fuel tank.


I have heard that in some vehicles, when the coil warms up, it operates sporadically. When the engine dies and it cools back down it operates fine until it heats up again and fails. This could be your problem.

Quits running after it starts to warm up under 1 mile


Try your ignition coil. That year model chevy has a dry running coil and it does not go out all at once. It will spark and run while cool but just as soon as the everything starts to heat up the resistance in the coil begins to build and it quits firing. After letting the vehicle set a little while and cool off it will fire off and run just fine untill it starts to heat up again.

Idles fine cold/ when it wamrs up it dies 1986 4x4 gmc suburban


This is only a suggestion because it worked for me. With a cool engine, use a can of store brand carb cleaner and spray the heck out of it. Get it into the linkage well and let it sit for up to and hour or so....stuff some rags on the intake manifold to soak up the excess. Then, after letting it sit, get your 'Burb up to operating temp. Should be the ticket for you....and no, your engine won't catch fire.
