who put the motor in? did you change harnesses?

when i first bought my car, it was doing the same thing. it was bogging when vtec engaged. it was also throwin a solid CEL.
it took me and a few buddies a long ass time to figure out what was wrong. i changed the vtec solenoid, distributor, plugs, wires, ecu.
come to find out, the SHOP i got it from had the wrong engine harness in it. my car is a 98 hatch but had a 99-00 engine harness in it.
we figured out the problem, changed the harness and the problem was fixed.

if you were closer, i would say i have a p30 you could put in there to see if that's the problem.
