I bought a 91' coupe with a blown motor and put in a KA from a 97'. I used the intake manifold, ignition and all that from the 91'. I did wind up having a broken injector and replaced it with one from the 97'. I think I've checked the timing about 6 times it may be only about a degree off.

It kind of stutters sometimes when it is cold in the 1800-2800 range. It also feels like there is no power above 3400 when it is warmed up and cold. It struggles to get to 80 mph.

My thoughts were I tore an injector seal putting in the new injector and at higher pressures it just robs the power or a vacuum leak.

Any help or other suggestions?
