ok another post i changed engines and now the new one wont run right at first it wouldnt idle right it was very high then revved up and down now it will start and run for a second and then die i replaced the iac valve made sure there wasnt a vaccum leak i bought a obd2 reader i hooked it up and got these codes
po300
po122
po113
reset it and this is the only one that come up po108
i dont understand why it would throw this many codes all at once when the engine blowed up but was running perfect b4 it blowed up also i replace the cam sensor and whole idi cover coils ignition module and spark plugs
any help would be appreciated
Sounds like you have a vacuum leak of some sort. There are many things that could be causing the engine to start up and die. Did you check the maf sensor? What are you reading for vacuum? what are you reading for fuel psi? If you rev it up does it stay running?
