Alright i finally got this figured out .. i had the car all day and it took me about 20mins to figure it out hahah
so..
The FIX
When on a hill there was alittle flex in the motor mounts which rocked the engine backwards.. causing a huge vacuum leak after the MAF (mass air flow sensor) and since someone before had the stock airbox removed and installed a K&N kit i could not hear the leak ..
This was after i fixed the problem haha
The culprit was the K&N setup: The K&N was bolted to the fender well and was not at the right angle .. so when the engine rocked back it pulled the intake boot part way off the K&N tube.. which caused the leak.. drive on level ground closed the gap ran like a top ..
sad thing is i tested everything before i found this out haha.....fuel pressure perfect.. TPS workin...
alright hope this helped lucky 7 ... it fixed my problem
but i would also look for tares in the intake boot ..
