so i am in the process of turbo swapping my car. i ran into an issue with the oil feed line so i just installed my header and intake manifold to try and run it NA for a few days... i start it up and it wont stay idled and the rpm jumps like crazy between 500RPMs and 4000RPMs. it pulled a throttle control code which i resolved, but it still wont stay running and when it does it sounds like the cycle explosion is about to come back through the intake manifold. i think it may be the spark plugs, but then again im not sure...


i got my alt welded for the new belt direction and i have the block tapped for the oil return. i have a 2.0 sc btw.

any ideas..

 

did you retune it?

You shouldnt run it NA with your SC tune.

As for the idling, check all your charge piping into the TB.

I know occasionaly, my charge pipe pops off when in boost when makes the car sound like its going to die...but then picks up..and does it again.

Check your MAF. Your Throttle positioning sensor. Make sure everything thats electrical was hooked back up
