doin a MPFI swap and i pulling a code four in my book it says its a Crankshaft Posion (CKP Sensor) is that the same as a crank angle sensor and if so how the hell do i fix it i have done every thing imaginable i even took my buddies ECU and distributor and still it pulls a code four. it also limits my revs to only 3500-4000 like the rev limiter almost like safe mode. its a 89 dx CRX

 

Did you add the wire to b15 correctly? Take that white clip out and push it in.. Check the green yellow and green blue wires on the dizzy wiring. I started my MPFI swap yesterday and am pulling codes 3, 4 5 14 15 16 lol I did it pretty quick, like 3 hours, now i just got to organize all the sensors and ****. After I get that done it should be running good. I had all these same codes when I did my first swap in my DX with a ZC.. So...
