Yes I did a DPFI to MPFI swap it is just about finished, but I have one thing left to do. I have a code 4 flashing and someone told me I need to switch 2 wires on the distributor and I don't know witch ones I switch can anyone help me. I think that is why my rev limiter is hitting at 3000 rpms.

thanks for the help

 

Blue wire is tachometer that reads out rom and the black wire is the ground inside dizzy.

Wow, that greatly informative answer is so helpful, I'm sure glad you're around.


OP, have you gone over your MPFI swap instructions carefully? We don't know how you wired up the dist, so it may be numerous wires. Maybe take a picture of your 7-pin connector for the dizzy and we can tell you what's what?

And yes, throwing code 4 will cause your car to go into limp mode.

 

Do your wires match up as so?

 

There are 4 wires 2 going to c1 & c2 orange, white crank angle and 2 going to b10 & b12 cylinder sensors.

Thanks
