vtec works for 10 mins then stops.
motor is filled with oil
no ecu codes thrown
changed vtec pressure switch
and vtec solenoid brand new today
my car hits vtec 1 time
then stops and will not work again till after i turn the car off or restart.
no oil leaks
never seen this before

i would guess its timing issues if u put aftermarket cam gears on it, the vtec controller is reading it different than stock, and would only go into effect once and would continue to think its still on even tho its not, if not then its ur vtec controller in the ecu is malfunctioning... if u kno some1 wit one or have the money, try another ecu

p13 vtec pressue grounded to the fender bolts

usually I ground the vtec with the t-stat housing. havent really heard anyone ground it out to the fender.
