first, CEL is going on for VTEC solenoid. A4 and D6 are already spliced for the bypass vtec oil pressure switch. so u run the solenoid switch and connect that to A4. CEL disappears. you run the car, pulls on VTEC. 10 minutes after test driving, CEL pops up again. VTEC doesnt kick in anymore.

here is the WEIRD part - when you turn the key into ignition, CEL stays on, then goes OFF for about 3 seconds. then CEL turns on again.

is this something weird? shouldnt the CEL stay on the whole time rather than turn on, off for 3 seconds, then on again? btw, could you guys take pix of how you spliced the A4's and the D6's to bypass the pressure switch.. most likely, im not doing a good job like you guys are.. thanks

low on oil maybe? lack of pressure?

Something that holds your oil pressure is loose so your lossing oil pressure to keep vtecing. On D-series vtec heads, we have a bolt on the vtec motion assembly, I don't know about b18cR's or any other dohc vtec's. Take your valve cover off and check.

I FIXED IT!!! ok, i dont know how many people use a paper clip as a "jumper" for the A4 into D6, but that's what i did. so for all you guys that feel lazy about splicing or soldering, try my paper clip method. am i the only one that has done this method? let everyone know your experience if you have tried the paper clip method.
