I have been trying to troubleshoot this problem and it hasn't been going very well. My VTEC only kicks in when the car is first started. When the car gets warm, no VTEC. I checked my oil levels, grounds, checked the screen, double checked the wiring to the ECU, changed the oil pressure switch, and even tried another selenoid. Still the same problem. Any ideas? I miss VTEC cruising on the HWY!!!!! Thanks in advance
