Okay.. i have a 93 civic coupe with a jdm zc single cam vtec in it.. recently took off the turbo and still have the resistor box on..(think thats why im throwing a fuel injector code).. Now it wont go past about 3200 rpm and breaks up real bad when it gets near there.. Compression tested it and i have 180 across the board then it started throwing that code and breaking up.. It has done it before after i put the ex z6 tranny in it but went away after a while.. Can someone help?
