1996 2.0 L zetec engine
idles too fast..
Starts Cold around 1100, then Drops to about raspy 650, then after warm, creeps Up to about 1700, rpm is slow to settle back down after pressing throttle.. Timing belt
is New, w/crank to cam setting correct:
@2nd mark of crank on pan line, and flat cam slots even & level & flush w/head...
(we tripple checked this)
MAP is new, all other sensors checked.. has no error codes..
filters clean, fresh 10-30 oil, IAC, egr checked ok, vaccuum lines tested -ok.
starts on 1st tick each time, no fluid leaks,
Runs fine on local road test trips here, except for fast idle problem..
vaccuum steady @20, engine has 59000, temp= 186 after warmup..
TPS reads 18% (.9v) at idle.
timing seems fast, reports about 31 deg @ idle, can't find reason foir this..
- we can't find anything else to check.. - have rechecked many things.
Q where can i take this to get it fixed, (reasonable) here in Fresno, Ca.
