What makes a car have a bad idle and stall when its warmed up?
I have a 2002 ford taurus ses and all my hoses look good. What can make my car have a bad idle and die after is been running for a little bit.
I have a Volvo, also year 2002. So I can't tell about your Ford, however, in my car, the problem was a little device responsible to automatically (electronic) adjust the idle of the engine. That little device had to be replaced (because car engines nowadays are run by electronics, so there's not a simple screw where you can adjust the idel, like in older cars/engines. (My old Honda motorcycle had a simple screw to adjust the idle RPM)
Maybe it needs a tuneup
- I bought an Actron CP9125 Code Reader to try and diagnose a rough idle at cold start on a 98 Ford 4.0 engine. The rough idle had not caused? The CEL to come on. I plugged the code reader in with just the key on and pressed read and the little asterisk goes half-way across the screen one time and stops. I press the read button again and it reads 0 codes. I was thinking it would scan multiple times to check for pending codes or other issues. I tried it with the engine running and the same thing happens. Is this code reader operating properly?
- Why Does Replacing Idle Air Control Valve on 2002 Ford F150 not correct Idle issue? Got A check engine light. Code said Idle Air Contol Valve. Purchased A control valve at parts store. Replaced control valve with new one. Engine Idled up real high. Attempted driving, thought computer had to reset. Engine still idled up too high. Parts store said vehicle had to be driven for at least 20 miles for control valve to operate correctly. Drove truck 30 miles, engine started to surge. Put old control valve back in and engine does not idle high or surge but stalls out.( suggestions) ?
