code 4 after MPFI still giving me problems!!
ok guys, i'm still throwing this code 4, i went throw all the wiring everything is correct. I have the c1 and c2 wires going to the blue green and blue yellow at the dizzy, i put b10 and b12 to the old c1 and c2 wires. I double check all the connections went through resoldered and heat shrinked everything, wrapped it more with tape and nothing. Both ECUs are good, both Dizzys are good. My last option is to wrap the entire wire with electrical tape and run it like that? I don't under this why is this not working!!!!!!!!!!!

If you know someone that has a car you can test the ecu and dizzy on, I would try that... See if it has the code 4 still...

Did you take apart the dizzy? I put a new igniter in mine a phucked the wires all *** backwards...
ok well aparnetly the power wire i had going to the back was affecting the signal to from the crank to the ECU? So i taped up the wires and all is well. Altho the tach is alittle jumpy i guess i need to go check that connection? but thanks for everyones help

That's interesting... For the tach, Pull the cap off the dizzy and make sure all the spade connectors are tight, It may help to use some dielectric grease on them, That's how I fixed mine. Good luck.
