As I stated in my Title... the problems consist of mis-fire, shutter, shake, and or lack of reving properly... She revs but not well and drives, but not worth the waste in gas to do so
Now what im working on is a 94 SSEI, supercharged glory... my first FI car and im just LOVING it... haha not really... I know that the check engine light is on but I havent checked the code yet, will get accomplished tomorrow, but i need to kno anyone has any input.
When you get in and start her up she fires up and idles intermittently at 1000 rpms... I say intermittently because it cycles up and down and loaps like its got a good size cam in it... lol a friend at first thought it was a drag car, but it holds idle... If you rev it up gently it goes all the way to 5500 without hesitation, sometimes a lil kick at 3000 but still climbs, now if you gas it and hold it at WOT the whole car shakes like its firing on 3 cyls. Mind you its boosting, has new plugs, wires, oil, fuel filter, MAF sensor, Coil packs, stress tested the Ignition module and it passed with flying colors, now im thinking the problem is a sensor (cam, crank, etc) or in the motor itself.
If you want to kno the background on the car, she was a freebee from my father...Been in his possession since 96 and he parked it for 3 years cuz of the EGR valve... pause for laughter... I kno, but after 3 mechanics in Tulsa, OK and his own work on it the conclusion to it was not running right was due to the supercharger, so he replaced it, plugs, wires, pulleys, belts, and fluids... still didnt run right so he parked it... til i took it off his hands... After 3 yrs of Tulsa winters i re-replaced the wires, plugs, fluids, EGR valve, and things of that nature to get her back up and running. Quite well aftually minus the charger quit boosting.
Now I have fixed the blowoff valve silonoid (spelled wrong i kno, i think), and got boost back, YAY!
but then less than a week later I got a major problem... The MAF sensor died... and i mean died... completely quit working so performance and fuel efficiency went bye-bye. Then after fixing that the fuel filter got clogged... this of course caused a problem with revving up, but was fixed easily. Now im onto the problem at hand... Seems like any time i fix something, another something goes ary...
Now im left with thinking im going to have to tear into the motor so i need some suggestions on what to look for. if there are any questions, email me at firstname.lastname@example.org
or reply... im open to anything because im stuck on where to look for a fix.
Sorry for the long story but i want all the facts and info laid out so theres fewer questions.
