i took the injectors out tested them and found some dirt around the o-rings they looked good and i cleaned um up... i didnt see any fuel leaks... but just so everyone knows this is whats goin on...
the car wont idle it sounds as if its missing or a cylander is out but if i rev it up it will run fine and it will come down in revs fine untill about 1000-1200 and it just wont idle worth a shit ive tried 2 AAC valves and 2 CAS's.. i did a compression test i got 1)170 2)170 3)170 4)180.. but it still seems that i am getting too much fuel.. i did replace the coolent temp sensor with one from my single cam harnes (its the little one with one wire going to it) should i try another one just in case? i have one from a s14 ka harness... and btw the mafs plug im using is from a dualcam ka harness and could it be that the wires are different from one mafs to another? like different order from male to female connection? lmk and maybe a picture of your mafs plug and the wire order while its connected to your mafs would be nice.. thanks and i hope this info helps
