i have a 1987 olds delta 88 royale with the 3.8 v6 and 63,000 miles, it started acting like it wasnt getting fuel so i replaced the fuel pump, strainer, fuel filter air filter, and sprayed a bunch of fuel injection cleaner into the throttle body opening, things got worse, now it idles really rough, but when u rev it up in park, it sounds good and revs fine, but under load it has no power and barely goes sometimes, pops n hisses... since then ive replaced the fuel regulator, idle air control valve, & spark plugs. The fuel injectors are all ticking and tested good with ohm meter, the timing chain and cam sensor were replaced 6 months ago... every now n then i get code 32 EGR valve, but i can puch up on the diaphram with my finger and it seems to work ok, yesterday i got code 34 air temp sensor, for the first time. Any ideas im going nuts trying to figure this out, i also ran seafoam thru the vac line twice now and it seems to help at first but fades away. could it be the ignition control module or coil? it also has the correct fuel pressure 45psi.... HELP PLEASE!!!
