Im having a problem. I have a z6 in my hatch and i recently swapped out the tranny for another ex-si one. Since the swap I have been having a CEL problem. When I start the car and drive normally it is fine, no CEL, but whever I hit VTEC a CEL comes on. Usually it is after I shift when it comes on. Then if I turn off the car and start it again, voila, no CEL. Anyone know how to fix this or atleast what the problem is? Thanks for the help

 

is your spedo consistent? bouncing? rpm's?
check oil level and pressure

 

Speedo is consistant.
I just checked my oil level and it is past the 2nd dot on the dipstick.... could having too much oil cause that? Should I drain some out?

 

how far past?
that's not the problem...
try pulling the vtec solenoid and cleaning off the screen and reinstalling it
or better yet try a friends.
i had one go out on me in the past. just pulled one off my old motor and it's good to go.

 

Have you tried pulling the the cel? I've seen this a bunch of times before, but cant qtuie remember what it is, im thinking a sensor.

 

Sorry but what do you mean by pulling the CEL?

 

"pulling the CEL" means finding out what the code is. here a how to if you dont know how to do it https://honda-tech.com/zerothread/1901557

 

Problem with that is I cant pull the code because when I shut the car off the CEL goes away....
