low fuel pressure tops my list.
does the cluster lamp CEL glow , key
then go out, running (idling) it must
of not that means scan me , if in usa, are you?
in canada its different.
this engine makes power in limhome mode.
so my guess , low fuel pressure. the FPRs are failing now
this old, btw
it can stick open and pressure drops to 15psi and not 35,45psi.
btw , that was guess, and as most guesses, useless.
i do the tests, and least the results tell me truth.
i can rattle off, 10 top reasons or or even 50 , inside engine.
Low power has many causes, does it help guessing?
there are like 1 to 10 tests, to do and bam, cause.
folks that love to guess, send endless useless cash.http://www.fixkick.com/power-index.html
I i can tick off many top causes
your engine dont read my list it does what it wants. fate, miles, abuse, bad service, endless this topic. truely.
1: needs a tuneup.,
2: compression (cyl) low, its and old car.
3: maf dirty
4: low fuel pressure FPR , is toasted.
5: cat melted.
6: huge vacuum leak , in the main induction and Air fuel ratio goes super lean.
that top pipe for air on top engine loves to fail
and large number of ways, and all LEAK AIR.
I seen over 10 like this. even broken mount to it and sucking air like mad.
those are the top fails as is a slipped timing belt
but that is part of the tuneup, its replaced at 60kmiles, if you skip this service point it fails.
it slips and compressing drops by 1/2 and so does power. seen 100s like that.
why not just get car serviced if you dont own mech. tools?
