my pride and joy is still giving me headachs
my last post i stated that my gasket was leaking: fixed it (i acutually replaced all my gaskets and vacuum lines and sensors) so (think) that is done. but the problem persists. after i start the vehicle i have to keep the revs up or it will stall, doing so and keeping the accelarator steady the engine surges 3 to 5 times then runs better for 20 to 30 seconds than the same routine. it does this about 4 to 5 times, then its gone for as long as the engine is running. if i shut her down and start her up 1 to ... minutes later same s*ht.
it's not an o2 problem nor a vacuum one. that leaves fuel or spark. all spark components : new.
during idle i can clearly hear a "whistling" "bee- like" noise ecoming from the gastank in my humble opinion: the fuel pump. is this normal? also when i turn the engine off i can hear a fluid run back to ...? idle is rough as well (i know for a fact that my MAT sensor is dead as well so that is part of the problem to?
1: are you suppose to hear your fuel pump out loud?
2:the running fluid in the engine compartment could that be fuel?
3: how much does the MAT sensor affect al the previous issues?
4: my filler cap rubbers all also rotten clear thru. will anew one help a lot?
i own a haynes manual but can't really find the awnsers.
this all concerns a 2.5 tbi 1990 yj.
cheers, in advance
