hi, i have a 95 gsr,5spd, and here's my problem, when i stay in vtec for to long,(EX: i'll floor it in first gear, go to 8,shift go to 8 in second,then in third right before i get to 8 rpm,s it happens),my check engine light comes on and put a rev limiter on at 6,400 rpm,s. then i can restart my car and the light goes off and then same thing will happen. It is a code 22,variable valve timing or vtec pressure switch.
k, i have replaced my vtec pressure switch,vtec solenoid,put a new gasket and filter in, cleaned everything,tried replacing the ecu with two other p72 ecu's,i change my oil every 3000, all that, no luck.
thanx for any help

 

hmmmmmmmm that is a hard one....... does the car hesitate before it hits the rev limiter to 6400?

 

only time my car hesitates is off the line
