hey guyz, i am having problems with my b18a swap into my 89 dx...
im gettin codes 7, 13 and 14.
code 7 - i got it to come off, lose wire at the ecu pins..
code 13 - map sensor?? i was running the same map sensor with the previous b16a in the same car... what could be the problem??
code 14 - the valve behind the manifold, i changed it twice and still gives me the same crap...

does anyone have any ideas about the not going pass 3k rpms?? I basically kept the same wiring from the b16a, is it the same besides the extra wires needed for the vtec, knock sensor and such... those are unused now.. oh yea im runnig a pg7 ecu right now..
thanks


on top of that, when i gas it, it bogs and just doesnt go past 3k rpms..

 

anyone??

 

may sound stupid but check to see if your sensors on the back of your intake manifold are in the correct location because the idle air control valve and the intake air temp sensor have the same plug and when you switch them they cause these kind of problems let me know if that is it

 

yeapz.. i tried that.. switched them both, and well either way the check engine light wont come off.. i did the same mistake in my first swap.. haha..
thanks for the input...

 

it is your map sensor, get a voltmeter and check that **** out...mine did this once, it was the power wire to the map sensor

 

try getting the helms manual for your engine. it's huge, and has really detailed and precise steps for fixing electrical codes. It has saved me more times than I can count.
