Ok... i have major problems with this car. I bought it this way and i am just trying to figure out what the problem is. I'll just lay it out for you.


1994 Civic EX coupe
D16Y7
P06 computer
D15B7 Intake Manifold w/Throttle Body
Cut/Spliced OBD2 Connections on OBD1 EX Wiring Harness
Fuel Cut/Rev Limit around 4800rpm.

I can not figure out what might be causing this. its very little power up until the cut, and revs extremly slow. Any ideas would be helpful.

thanks in advance.

 

your rev limiter is at 4800? and im not familiar with d series but that is one fu**** up setup i would never run imo

 

Yeah im not wanting to run that..lol... I purchased this car from a guy for the body and interior. didn't really care about anything else on it. after i got it home i started looking into this and was wondering WHY it stops at 4800. Got any ideas?

 

maybe theres something wrong with the ECU?

 

pics?

does the ecu looked chipped or custom in any way?

 

might be the ecu or the wiring harness. I dont really trust anyone with wiring unless i do it or someone I know that know how to wire do the wiring. lol

 

I just went outside and got the ECU out of the car. The numbers are

37820-P06-A00
740-510122

I opened the ECU up once before and i didnn't notice anything out of the ordinary. it does say on the side of it Dec 11 91. I'll Get pics ASAP

 

the whole thing looked to be a F**K job as a whole.. im pulling the engine and everything anyways for a B-series swap.. but i just wanted to know for the technical side of things. for the sake of knowing you know. lol

 

maybe its running in limp mode to protect itself? do you have any CELS

 

the CEL comes on after about 10 min. see when i got the car the MAP and TPS were messed up. car would die if had no throtle etc... we changed the intake manifold to a D16Y7. car barely ran. changed back to the D15 and it runs descent until 4800

 

clean your throttle body and injectors ^__^ it might help and check your harness

 

check all your plugs and make sure none of them are switched around and check all the pins in them
