The car in question is a civic with a '96 B18C1 swap w/ obd1 GSR ecu. After my car warms up and I'm in VTEC for a couple of seconds, my CEL will usually come on and stay on until I shut the car off. The next time I start the car, the CEL will be off and the cycle repeats itself. Any ideas?

I haven't noticed any adverse driveability concerns, by the way.

 

Check your cel first

 

it's hard to check the CEL the standard way if it's off every time you start your car.

ps -- I'm having nearly this exact problem.

 

Try another ECU?

The ECU's stores the code... It doesn't go away just because the light's off.
