Ok I have tried looking through the posts and im not finding what im lookin for.. My 89 302 EFI is lacking power after it warms up.. I have all new plugs wires cap rotor and fuel filter.. Any ideas on sensors that i can change or something?
loss of power can be many things like a engine missfire which could take all day to explain, poss broken or clogged converters, fuel pump, also ignition timing, even leaking intake gaskets. if youre not familiar with diagnosing these potential problems then a competent shop is recommended. otherwise youll wind up draining your bank account trying to figure it out by throwing parts at it.
Yea the report said i was about 100 points too high on my NOx and all of the associated sensors are fairly new and if they go the check engine light will go on. The mechanic told me it was more than most likely the egr and as i stated before if i do it and that isnt the problem i get a waiver sticker.. The other thing could be the cat. If thats the case i plan on re-doing the exhaust anyway so in the process of things that i want to beef up alot of the things that are possibly causing this will be replaced anyway.
