Hi guys. I fired up my new motor last night. We hooked the car up to the Modis and it is throwing a knock sensor code and is getting out of control amounts of fuel. At this point I bet my plugs are fouled out and it is breaking up bad when we took it for a ride up the street. It's even stalling out at times. I'm wondering if this has anything to do with my Ford 30 pounders and stock tune. I wanted to save my money for a dyno tune now but maybe a mail order for the time in being is what I need? Help me out!

 

A mail order tune would get you running at least, money well spent
You can always dyno tune later on if you want to.

 

ya it IS the 30lb injectors. Your computer thinks they are 24lbs so its throwing enough fuel for the 24lb injectors to feed, but since you have 30lb you are putting waay too much fuel in there. Put the stock ones back in until you get it tuned.
