Idles to fast

When i crank my truck it runs wide open for a minute or so
and then it starts to idle down what causes this. it is a 1992
chevy S10 v6 I have a chevy Cavelier 84 and it starts ,and idles very fast and when i put it in gear it runs "normal" not as fast . But when the engine gets to about 190*) to 220*) the car stals after I put on the brake and then it wont start again until it cools down. I am a female and I am thinking it is somthing to do with the thermastat,or transmission problem?

Sounds like a vaccum leak at the throttle body or the intake. check for loose lines hissing with the motor running. Had a brake booster line come loose on my 92 and it ran at about 3000 rpms.

My Chevy S10 2.8 idles fast in cold weather. What can I do?


Sounds like the fast idle screw needs to be adjusted on the throttle body or if it has an IAC, it may need to be replaced. A little more info on the vehicle might help to narrow it down.

96 chevy s10 v6 stalls after i start it up


This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

I have a 1991 Chevy s10 fuel injected 5spd and at stops the engine does not idle down after decelerating, instead it idles halfway wide open at stops. I would like to know the solution to this if possible,...


It is the gasket underneath the throttle body. It is being sucked in at one corner causing a big air leak which caused the engine to idle at about 2500 rpms. You will probably have to buy a throttle body repair kit which will include a new gasket. This should fix the problem. You didn't mention engine size, but I think the 2.8 v6 is the engine that had this gasket problem.

Engine will start at very low idle, sometimes killing, then may fast idle, then low idle, back and forth. What may cause this?


check and make sure air filter is ok, and there are no restrictions in hose to throttle body, check iac (idle air control.

Cranking & Idle issue 92 Isuzu Rodeo


could be many things. Could be choke causing problems, could be engine temperature sendor bad, could be EGR. When you mean engine light comes on do you mean service engine light coming on? Probably has codes set which means something is gone wrong and setting a code that tells the tech what is wrong or what to look for. Have you changed your fuel filter lately?

Carburator tune up of charadade 1992 sedan. The engine is running too fast while idle at 1200 r.p.m.


Before you start check the status of your choke. One that is stuck on will cause a high idle. If the choke checks out, proceed to the following:


You should have what's called a 2 needle carburetor. A larger screw adjustment for idle, and a smaller for high speed.

Start by adjusting your low speed (idle) needle until you reach the desired idle. I prefer about 850rpms. Do this with the engine running and adequately warmed so that your adjustments are not thrown off by the automatic choke.

Next slowly open up the high speed needle. As you open it your idle speed will gradually increase. Adust it in 1/8 turn increments, pausing after each adjustment to allow the changes to take affect. Keep opening it until you stop increasing your rpms, then take it back 1/8 of a turn.

Next readjust your idle mixture screw so that your idle is back down to 850rpms.

Idles fast


Most likely an air leak/vacuum hose problem. There could also be an issue with the throttle body base gasket. The 4.3 engines are known to rev a little high but a small air leak can make them rev really high when they should not.

Idles to fast


When I crank my truck it runs wide open for a minute of so and then it starts to idle down. What causes this? It is a 1992 Chevy S10 v6 pickup. How can I fix this problem? I have no manuel on this vehicle for a diagram of the engine at all.

Thank you. Dave
