I recently started getting the check engine light out of nowhere. It is on with my TRAC OFF light. Does the check engine light always come on with the TRAC OFF light?

I tried doing the diagnostic as explained here:

http://mkiv.christurner.net/techarticles/engine_codes/obd1_codes.html

I thought I was supposed to count the number of times the check engine light blinks while having TE1 and E1 connected? But all I got was the check engine light blinking infinitely. After disconnecting the wires from the diagnostic box, the check engine light was gone but came on after about another 50 miles.

I'm BPU except the downpipe. My guess is either the BCC is causing it somehow, or the EGR (I haven't done the EGR mod yet) What do you guys think?

Any feedback would be appreciated.

Thanx,
Ash

I had an intermittent problem like yours. It was my main o2 sensor. How many miles do u have on your car? Does your light stay on? When my resistor went bad in my egr, my ce light stayed on.

Good luck,
Sid
