Having searched the forum extensivley, i still cant find any thing conclusive. this is my second go
1992-500sl Symptoms Cold starts - overnight, starts fine , although engine fires aftera longer turn (2-3 secs) Afert 30 min-4hrs- takes 2-3 cranks (ignition on fr bout 10 secs). starts perfectly (half turn ) if started withing 1/2 hr. Things changed /checked 1. distrbutor cap, rotors, 3 suppressors 2. ignition coils (3) 3 spark plugs (3 had carbon) 4. fuel pumps/accumulator/ filter. 5. checked fr vaccum leaks(fixed leaking injector seals ) 6 two doses of fuel injector cleaner . 7. no fault codes . 8. cleaned idle control valve. I am going to get lambda tested tomorrw , as the car idles at 600 in D, but rough idling at P,N. and post findings here. been trying to crack this fr a while , and i came across OVP as a culprit, what is the closest substitute in sl (as i think they do not have an ovp). I did jump start my car about a couple of weeks before the problem started , and dont want to leave this stone unturned. I definitely need a pointer in the right direction , and dont want to throw any more monet at parts that may be unwarranted. Thanks for your efforts in advance!!! |
