Hello again!
Due to some RL issues I had not much time to spend on my car (sadly)...but I've done some work on her...
PROBLEM:
- Fast idle at cold starts is dead. Just goes from 400 to 900-1000rpm in 2seconds. But it start at 1st try.
Then I hear the engine "trying" to rise in rpm with no luck...(rpm sound is like increasing and decreasing. just a bit, the rpm indicator cant recognize it but I can simply hearing the engine noise)
- when hot, the idle stick at 900/1000rpm. If I give gas then fix to 800-850 (all accessories off)
- Engine shakes quite badly when at IDLE. Hot or cold is the same. Seems like is misfiring...
- after driving, if I stop (engine still on) rpm stuck to 1500 for like 10sec. then 850rpm idle. This occurs sometimes not always...
WORK DONE:
- new rotor cap.
- new sparks (NGK BPR5ES)
- new spark wire (NGK blue)
- new exhaust mainfold with gasket (the old one was cracked)
- cleaned the whole TB
- cleaned the ISC valve and tried another one (but nothing changes)
- checked for valve lash (0.15mm in and 0.19out)
- dashpot seems ok
- all hoses replaced (just to be sure)
- EGR valve closed (with a plate)
- new fuel tank (the old one was full of rust)
- new fuel pump (the old one was gone...) + fuel filter
- engine mounts are quit new (1yr old)
Best regards!
