Hey, i need help bad.

I just swapped a zc motor in a dx crx

it cranks up and runs and all but it revs to 5000 rpm and just sits there.

It gives me a code 8 on the pr4 ecu
I replaced that sensor but it did not fix the problem

any help with would be great.

If i could call any of you for help- I will do it thanks

 

Oh and i unplugged the tps
and it did the same thing still revs up to 5000 grand
if thats any help

 

Can you use a PR4 ECU on the ZC
I got a PM7 Euro ECU if you got some $$

 

you can use a pr4 ecu but you'll just have a bit more of a fuel odor. so you are saying that the motor starts but it just sits a 5k. ok...now...if you open the throttle...will it rise?..did you switch teh 2 outer wires on the tps? did you mix the iat plug witth the iavc plug? Is the throttle on tight? did you resent the ecu..and erase the code? just my 2 cents.

 

do all that above.. and cheeck vac lines for proper connection

 

Yeah check vac lines
