Okay so I put a d16 non vtec head on my d15b7 block car starts fine is on time runs and drivesbut it wont rev past 3000 rpm sounds like it has 2 step in every gear....sum 1 please help me diagnose this problem

Ur ecu is on Limp mode. You should have a cel on. Find out what it is. Most of the time it's a wiring issue. Or tps and map are mixed up.

Check that ur iac and tps sensor are not mixed up cuz the plugs look alike but would throw the wrong signal to each other and make car run funny..hope this helps

Iac does not have the same plug as the tps.
