i have just swap a 94 b18c1 into my ek. everything went fine til we started it. it keeps idling up and down from l.5 to 1.6 rpm. doesnt matter wether its cold or it warmd up already. it also feels like its choking wenever i drive it.everytime i step on or let go on gas it boggs and cannot keep on a constant speed.and of course my check engine light is on.
couple of my buddies say its either not enough fuel or probably my wirings wrong.
im running on stock p72ecu, have converted obd2 to obd1. pretty much stock except for walboro 190 fuel pump and have a jge intake manifold and basic h/i/e.
any advises here???

 

Find out why your cel is on and start from there.

 

how is the tps sensor? did you calibrate it correctly? that was causeing problems for me last time i did a swap.. check it out..

 

imo i think u cross wire it and should check on it or get someone to check to see if u did it right
