S14 Sr20DET bogging out
Hey guys,
So question for all you SR guys out there that know everything =) I've got an S14 SR20DET in my s14 right now. Ive got everything repinned up and the engine is running. My question is: What would cause my engine to bog and run super rich at low RPMs? My engine hits up to 4k RPM and sounds great and has full throttle response. but like i said, at low RPM and Idle, as soon as i give it some gas it bogs down bad with slow throttle response and is back firing and running super rich. smalls like gas bad from the exhaust. So jsut wondering what some trouble shooting procedures are that I could try? Thanks guys! |

Exact same symptons I have at the moment.
