Rough idle after engine is warm


Dirty air filter, dirty throttle body...try 2 bottles of gas line fuel injector cleaner...has your car been parked for awhile? Heet gas additive will work on any low gas tank sludge that you may have. Hope this helps.

Honda element 03. Normally starts up at 1,000 rpm in park and shifts into drive smoothly. Sometimes starts up b/w 1.5 and 2k rpm at idle and JERKS into drive or reverse.Solutions?


Cars not control choke themselves electronically, this is likely the car trying to warm itself up quickly. The jerking will occurs anytime you shift into gear at an RPM over a low idle as the torque converter is being engaged. If the high idle last more than a couple of minutes then you might have an issue.

Over revving


Check for a vacuum leak. This can cause a higher than normal idle. It can also cause a surge since the idle air control tries to adjust the amount of air required to idle.

My car slams when put into drive. is it the idle


Yes, sounds like the idle speed is too high. If you keep driving like that, you will fry the torque converter / turbine. Since idle is computer controlled, you will have to take it for service tune up. There is one possibility that the rich, high rpm idle used for cold start is not disengaging properly after the engine warms up. Air conditioning will raise the idle speed by a couple hundred rpm, so avoid using it until you have the problem fixed. BTW.....warm engine rpm in idle, and neutral should be around 700-800. Anything over 900-1100 will result in a hard shift into 1st gear and dragging at stop lights.
