what type of idle problem is it, in my old Jeep grand cheroke i had a problem where you had to slightly press the throttle in order to stop the engine from stalling at idle. this problem was later found to be due to to much deposit on the electrodes of the battery. Another problem i had on my vw polo was when the ignition coil went on one of the cylinders. i do know that idle problems are mainly due to ignition faults unless you've burnt a bearing.
Depends on where the noise is whats making the noise. Can you be more descriptive of where and what?
whats the problem for my 94 ford van engine high and low idle
Your car may stall or stop running after idle because of a problem with its fuel or electrical system.
If your 1997 GMC 5.7L Vortec has a misfire at an idle but not while under throttle, the problem is likely the timing. This can be adjusted.
plugs or vacuum. 65;
Possible base idle too low!
It is very likely there is no way to adjust the idle on your car. If your car is idling low, it's probably a problem somewhere else. Idle is likely controlled by the computer.
what year car and whats the problem
could be the regulator
Most likely a Fuel/Air mixture problem
The idle is set too low or there is an electrical problem
If car is coughing and stalls out until you drive whats the problem.
