I have sohc vtec in my 88 dx, and throwing code4. I change distributors, swapped wires, redid the connections, and still won't rev pass 3200rpm some one please HELP.

 

did you do the mpfi swap? you may have not have made a good connection on the wiring harness. i can't remember what pin it is...

 

the pins are c1 and c2 and they are both in and I just wanna shoot my car already.

 

reset the ecu.

 

is the new ecu known to be good? sounds like a long shot but it once happend to me.

 

pull the c1-c2 wires again and squeeze the connector that goes over the pin. sometimes when you pull them out they will stretch and not make full contact.

that was my problem with my buddys car.

 

I'll try that. I also tried using my friends ecu that is known to be in good working order and nope it doesn't work. i try tightening the pins though.

 

it might actually be the distro...this time....

 

yeah, i would say check the dizzy... i had the same problem and replaced mine to fix it
scott

 

i have the same prob... replaced the dizzy but have yet top check thorolly threw the wires i looked though and it seemed fine ... bump

 

I changed the distributor to a used jdm one and still doesn't work. I'm probably going to rerun the wires tomorrow with some brand new one and not one from a wire harness. I also will be redoing the timing belt tomorrow too. I let you guys know the outcome.

 

im pretty sure i know what your problem is you have your crank angle wires in the wrong part on your plug i bet you have them in b11 and b9 if so there upside down and not getting any signal to the crank make sure there in b12 and b10!!!!!!!!!!!!!!!!!!!

heres another pic of an example to look at [IMG][/IMG]

 

Isn't the wires supposed to be in pins c1 and c2. The motor did rev up like two great times which lasted like less than 24 hours with the way the wires are now, so i don't think that is the problem.

 

what ecu do you have?

 

c1 and c2 where supposed to be cut and put into b10 and b12 for crank angle sensor then back to c1 and 2 run wires for your cylinder position sensor

 

I'm using a chipped p06 right now and currently waiting for my p07 to be chipped. The ecu is non vtec but it doesn't matter, i can't hit vtec anyway.

 

Did anyone ever find out what the problem was to this senario??? I have a 91 civic si with a d16z6 Swap. I'm running the 91 (D16a6 dizzy,ECU,injectors, and the ignitor box). When I first drive the car the thing zips around great, once the engine reaches a normal temp I have the same problem mentioned with the studdering at 3200 RPM's. Any and all help will be appreciated!

 

I have a d15z1 block with d15b2 pistons, d16z6 head, d15z1 ditributor, a p06 ecu d16z6 injectors. I'm running obd-1, I heard that it supposed to be safer, or something like that.
