I hit a big bump on the freeway while vtec was engaged,i drove my car the next day and now it drives just like a Si.I had a diagnostic done and they said they can't find anything wrong, but they didn't check the o2 sensor and solenoid.what's the deal?????
94 prelude h22 i have a P13-N50 ECU

 

you probably hit your oil pan on the ground and now it pushed the pan up enough that its not letting any oil get to the pick, you need to check the pan.

 

what's the pick?? Is that what sucks the oil in to the engine or for vtec?? anyway I am goin to get that checked thanks man , i totally forgot about that, thinkin it's some big ecu configuration ha,

 

my bad the pick up, its what supplies the oil pump.
