Hey guys, I recently swaped a obd2 LS into my 5th gen DX. I got the obd1 computer but am using the obd2 harness, dizzy and injectors. Everything is running good and smooth with the exception of one thing. Once I start the car its idles normal for a couple seconds then a check engine light pops on and the idle jumps up about to about 1300 rmp and holds. The car is also running super rich and mpg sucks......now I pulled the code and it registered the MAP sensor being the culprit.....I also changed the O2 sensor just to be sure but nothing changed......Im hesitant to think is the MAP because those syptoms dont seem characteristic also the motor only has 48K on it. Also should note the previous owner had an ITR motor in it. Any suggestions would be very appreciated!!!!
