Double check wireing. Make sure you hooked up the blue VTM wire, properly grounded per instruction, and check you oil level. Low oil (oil pressure) will cause your problem too.

 

yea everyting looks fine wired up... how can i check the oil pressure, and whats it suppost to be at?

 

if vtec is kicking in and out and it a oil pressure related problem, first thing I would do is check the dip stick. Beyond that, get an oil pressure gauge.

Upon checking the wires, are you sure the brown ground wire is grounded closer the the ecu, followed by the black ground about an inch futher back.
