I would like to know what kind of car this is. year and make. but yu could try replacing the EGR valve. i had a 1995 saturn sl2, egr valve had been ruined somehow and believe it or not i replaced it and it stopped idling high. although the egr vlve has nothing to do with rpm's it could be relaying a signal to the ecm to make the rpms rev higher than normal

My 1998 Vortec 5.78L engine will idle fine until I drive it for a while and then it idles fast. Sometimes faster than others. I do not have a tach, so I do not know how fast it is idling, but it is hard...


Hello

I know this is going to sound way to simple, but I would look for a air leak on the intake side. The reason I say this is that your engine runs because the computer feels it knows EVERYTHING about EVERYTHING.. Kind of like *********** N law. Well, when you get a vaccum leak, the computer doesnt know its stupid and raising the idle or POOR idle is one of the effects.

Now I am not at all saying this couldnt me something much more difficult, however VAC leaks are also pretty easy to check. Get yourself a can of SPRAY CARB CLEANER from your local parts store, some times gas stations have it too, wal-marts and places like that have it. Start your truck and SPRAY the CARB CLEANER around places that could have a VAC leak. Like hoses, the intake manifold gaskets and those kinds of things. If your engine suddenly runs REALLY ROUGH or even DIES when you spray a certian spot you know thats where your leak is.

I hope this helps you as much as it helped me

What kind of carb does the 76 c10 4x4 come with need to adjust


mcdevito75 here, The fast idle is needed when the engine is cold to make the air and fuel mixture rich to keep the engine running while cold, the carb. choke doew this with a bi-metalic spring in that balck round box on the side of the carb, a screw also hepls keep the choke closed until warm up, this screw can be adjusted tpo control how tight it holds the choke cloesed, here"s how to adjust this screw to slow fast idle speed, Locate on the carb, where the gas pedal connects, have a friend operate the gas pedal with the engine off, once you locate the linkage, you"ll also see 2 screws with springs around them, 1 is for fast idle the other for regular idle, you want the fast idle screw, notice this screw will lay against and Half moon shaped tab, while the other screw lays against a shaft, you need the screw that lays against the half moon shaped tab. Start the engine and step on the gas pedal slightly and relaease, at the screw that lays against this half moon, simply turn it counter clockwise or toward you just 1 2 or 3 turns very slowly, you'll hear the fast idle come down but you don"t want the fast idle to low, listen to the engine very carefully, slow it down just a bit, it should still race though but not out of control. Of course for a full carb, adjustment the shop should handle that., but this info will help.

2000 buick century idles fast when cold I let it run for couple minutes turn off start back up and idles just fine


Is the car idling faster than it has in the past when cold? The car is designed to idle a little faster than normal during warm up, to warm the engine quicker, and to keep it running. The fuel/air mix richens, (more fuel in the mix than normal), during start up conditions, and then as the engine warms, it should idle down to normal. Have you allowed it to continue its fast idle to see if it idles back down? Your post indicates that you turn it off and re-start to prompt the car to idle down. You have electronic fuel injection. The system adjusts to the prevalaint conditions to give you the perfect mix regardless of the condition it is presented with. It gathers input from a series of sensors that detect engine temp, outside temp, humidity and air pressure, to deliver the mix it needs. Often, when the mix is off, it is a result of a faulty sensor. This can be detected by running a fault code diagnostic check. You can have this performed for free at most national parts chains such as advance or auto zone. Other factors can cause an improper mix, such as dirty or clogged injectors, and/or a dirty air filter. Good Luck! I hope that you find this to be very helpful!

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.

1979 cj replased carb idles tohigh


Even with a rebuilt carb you have to make the adjustments. Check the choke adjustment and set the fast idle. If choke is to tight it will be hard to start and take a long time to idle down. The fast idle sounds like it is high also.

Will not drop down from fast idle when first started


It sounds like an automatic choke system. Let it warm up for 5 minutes and then give it gas up to 2000rpm and release.
