i just put in a jdm b16a2 into my 93 del sol...i kept the original wiring harness from the car cause it came with a d16z6. i put the b16 in last weekend and it fired right up...i wired the knock sensor into the ecu and had to extend a couple wires...the only problem is the engine doesnt idol quite right and when i stab the pedal to floor, when the car is in neutral, when the rpm's drop its almost like the engine wants to quit...it also is lackin power...the check engine light is on and i checked it. it spit out code 2...oxygen content i think...the ecu is a p30. i read that the p30 was made to read 2 o2 sensors and i have only 1...i also have p28 computer and i read that you are not supposed to use the p30 in an obd1 swap you are supposed to use a chipped p28...could that be my problem??? im stuck if anyone can help that would be awesome
