whenever i rev my car up to 5100 (my vtec crossover), my check engine light comes on. but when i turn off the car and start it again, the CEL goes away. it seems like it only comes on when i hit vtec. i have a z6 and my fpr is set at 45psi. anyone know what the problem is??

my setup: cai, header, exhaust, fpr and gauge, spoon chip, skunk2 manifold, 62mm tb, plug wires, alt. pulley, short shifter, removed p/s, removed a/c.

check too see if you getting enough oil pressure, make sure you have enough oil too, by the way did you ever check your rocker-arm assmbly. i had that problem before and it was because of my vtec followers were stuck with all kinds of oil crud build-up after i cleaned them they started to loosen up but i was still losing oil pressure sum where, it was at the vtec solinoid the screen inside was clogged with all kinds of crap, wont hurt to check it.

Oil and oil pressure could deffinatly be an issue. Is VTEC deffinatly exgauging b/c with stock Honda ecu's, if there are engine problems, the car should not be able to enter VTEC. With a different ecu however it might bypass this Honda system. If you have your old ecu, throw it in, I belive if the car is having a VTEC related problem the engine will cut out before crossover.

Someone correct me if I'm wrong.
