i did the dpfi to mpfi on a 88 crx with a zc motor. The car starts, idles fine but has a rev limit at 1500rpm. the ecu is coding for 4, 10, and 14. i've double and triple checked the wiring, even redid the ecu wiring. anybody have a clue what could be wrong?

 

bump?

 

code 4- ckp sensor "crank position sensor" recheck your distributor plug pin locations.

these next two are easy and obvious.

IAT "intake air temp" its the sensor that is on the #1 cylinder intake runner, usually white.

IAC " Idle air control" is the thing at the back of the intake manifold with two coolant line running into it.

you have em both switched.
