So I just swapped my 94 engine harness with a 95 harness due to some burnt wires. Not sure if this has anything to do with my current problem. I started the car it idles fine maybe a little high but as soon as I put it in gear it bogs down and runs real rough. Any ideas throttle position sensor....?

How did you do that, seeing that the two harnesses are not the same? If you did not do any repining to C105 (which 94 cars don't have), only half of your injectors have power.

Yea I I ran the tan serial data signal to c220 but there is the orange and black which is trac control system spark retard in c105 but in the 94 the spark retard request is in c220 however it doesn't continue

Wait I see the Pink in c105 on pin B do I need to move it to c100 pin K

shbox

Yes, that needs to be mated for injectors 1, 4, 6, 7 to get power.

You are my hero I've been fighting this car for 3 months trans shop melted my harness on headers and a battle ever since I do have the computer from my 94 and the 95 which one should I use

So is that it other than the wires in the kick panel

That's still odd that it would idle ok with being down 4 cylinders

If you got it running, I would say you probably got all the other wires mated up. It does not take much fuel to idle. Consider the newer engines that deactivate cylinders while you drive.

Got all wires mated up still got a nasty miss somewhere
