ITS A LOT TO READ, BUT TRUST ME ITS WORTH IT
okay so igot the pg single runner intake mani installed at pg! YEEEAAHH....so that was a pain in the boothay lol. The car would idle...and then die. It would give it self gas like crazy, and the idle would be all over the place....and then die...Well there was a vaccum leak, pg fixed that, YEAH! Well thennnn (we installed a new throttle body too) and the spring was loose so whenever you would hit the gas...the throttle would stay where you put it...ie when i backed up and let off the gas, the car accuatly accelarated backwards and kept going in reverse. Needless to say scared the crap out me. Okay we fixed that...YEAH! Well thennnn the car is suposed to have rougher idle and harder cold starts with this mani right? But my boost/vac guage reads about "8" at idle and about "18" when cruizing!!! Also my car would die when started...unless you gave it gas...and at idle my lil' 4-banger sounded like a 440hemi. It was rumbling and stuttering like crazy and ppl said it was an obvious misfire. I was like "nah, its just the new intake mani" wellll i got a CEL the next day..guess what two codes:
P0300
P0340
cam position sensor and random cylinder misfire!!!
(bang)
now im mad, how can this happen!
obviously if the cam position sensor "magically" went bad a week after the intake mani install that would cause random cylinder misfires if its getting a bad reading from the cam position, duh! But what the heck about the vaccum guage! "8" at idle and "18" while cruzing!!! Other than that when the car is under load it feels fine! If i let of the gas when just cruzing and hit the gas again...ie letting of the gas, the car bucks like a bronco when i both let off and get back on the gas...and the a/f rations jump to 11 when i hit the gas again. Mind you this is just cruzing and trying to keep the same speed...it seems almost impossible to keep the speed...possible promlem due to the cam position sensor?
PG looked everywhere for vaccum leaks and found nothing, i even have brandy spanking new vaccum lines put on and vibrant vaccum distribution block.....WHAT IS GOING ON! Could it really be just the cam position sensor causeing the wired vaccum guage readings, strong bucking of vehicle, and horrride starting?
ok typing complete.....lol

) so idk whats wrong...its only idle and cruizing that the vac is whack...it also smells like gas. The tune may need a lil work but, come to think of it i have one theory..
