So i just bought a 91 ef has a d15b1 thats been converted to mp and it has high ruff idle and i can smell gas alot which im guessin is from running rich as well as some white exhaust smoke.
so i checked the ecu its running the pm6 and now if its not the ecu im stuck

reving to about 2500 on start up. and varies from 1500 to 2500 during driving around.

smelling lots of gas.

any advice on where i should start looking?

please and thank you

 

check each part of the fuel system that had to be changed when converting DPFI -> MPFI. first thing is your injectors. ODB1 = no resister box. ODB0 = resister box. Even with the resister box teg injectors will run rich. make sure they're for your engine, Civic SI preferably

 

ok ill check that how i will know what it looks like?

 

it could look different depending on which model they pulled it from. usually a black box. one wire in, and four wires out to the injectors. best thing is to find someone who knows what they're looking for.

 

ok well i found it ,but how can i tell if its the right one . it should b the manifold off the the z6. as well as all other parts off of it . but the guy could have done somethingy fishy.

is there anyway i can test it? to see which one it is or some sort of identification.

thanks for your help also

 

pics of the engine bay maybe we can help u out betta

 

ok ill look some up

also did i mention inside the car when im driving the fuel smell is so bad.

is that because the car is running rich.

or do u think it could b becouse of something else.
