i have a 1993 honda del sol i just finished a d16z6 swap into it and i'm hitting a rev limiter at 3500 rpms i'm not throwing a code its not my distributor or ecu i've tried switching these already anyone else have a idea. i'm at my end with this car....

 

your in limp mode for some reason or another.

 

Does the CEL work? Is the mechanical timing off by one tooth on the timing belt?

 

this motor does not like timing to be off. re- check that and try new plugs and wires.

 

ok this just in i guess the engine was in a obd2 car, which actually expains alot... i believe it has d15 injectors in it compliments of my little brother trying to bring it down to obd1 again could this be my problem??

 

so you have a hack and slash half assed obd2 to obd1 conversion going on in some way?

 

make sure the cel is working and maby swap wiring harness
