Yea, like the title says, already replaced the switch...did nothing. The CEL comes on and the car sputters and runs terribly...until vtec engages, then the car runs fine...where should I go next to diagnose the problem...?

 

You check the wiring?? Make sure nothing is shorted or grounded.

 

from what i can tell all the wiring is good...i even re-ran the vtec pressure switch wiring from the switch to the ecu...
