I have A 96 ek coupe all stock but idk if previous owner chNged the injectors to obd1 for?? Tune up has been done. But it still Boggs cr
2500 rpm to 4500. What would be the problem?? Check timing is good. Maybe fuel pump? Spark plug changed and fuel filter n cap n rotors wires.. Maybe clean the injectors?? Only 93k.. Some help would b really grateful!

 

I don't know if you are even still having this problem since this is an older thread... But I would make sure to check ALL of the connections going to the intake manifold. Sometimes one of those plugs will come loose, or get unplugged. When I had the sensor on the back of the IM unplugged it ran like absolute crap, and wouldn't even really hit VTEC...sounds like you Might have the same issue?

 

Any check engine lights?

 

No check engine light. I will double check my wires but they use a obd1 injectors.. Idk why.. I try using another distributor but still same problem.
