Default My VTEC engagement is buggin...

So this has happened twice now and I am looking for some insight on why.

this is the ls/vtec i just did.

no CEL, nothing disabled in crome, cept the usual stuff (ie, all vtec stuff is enabled)

the first time was last night, i was cruisin around and rippin on the car a bit, then when i was on the freeway heading home, it didnt engage. I pulled over, checked all my wires and coolant and oil levels, everything checks out. turn the car off, back on while i was sittin there, leave the parking lot i pulled over in and it engages fine.

the next time it happened was today on the way home from work. im cruising along on the freeway, take my exit, and take it up from the stop sign onto the sidestreet i was on...doesn't engage. previous to pulling onto the freeway, it was engaging fine. get to the parts store, buy my ----, and leave and it engages fine...

so what should i start lookin for? other than a rope...

mabey check the screen on the vtec solenoid gasket? Also when its not working get out of the car and see if its getting power with a test light. Or the rope works fine

If it's not the screen, suspect oil pressure problem. The fact that you still have sufficient pressure at the VTP makes me thing you have a problem with your VTEC engagement assembly... pins sheared, fubar, something.

Wes CRX does that, he used a carboned up B17 head off an engine that had tossed a rod thru the block when it was run out of oil. 404 whp, sometimes
