Question Flickering CEL

Any body ever had there Check Engine light just come on and off randomly. No APPARENT problems with the '94-runs like it's new, just CEL light comes on for a couple of days and then takes a day off??? Today we went to smog it in CA and the light was off but Popped on as we rolled up to the shop! DAMN..I guess I'll pull the codes but this is crazy

Pull codes - I bet it's knock sensor.

Yes, it happens every now and then. The only way to know why it comes on is to check the codes. Good luck.

Yeah, knock sensor or O2 sensor. If you're not sure how to check the codes they are in the howto locker or on http://svx-iw.com in the SVXipedia

Menarius you are right. Turned out to be the left side knock sensor (28) and the right side 02 sensor. Replaced the 02. Now I need to fix the knock sensor. Looking at it seems I need a dwarf with little tiny small hands to get to it...or yank the intake. CAN I really get to this without taking off the intake'?

Yes, you can do it without removing the intake, it just takes patience and time. Read the how-to docs on the procedure, and they will help you ALOT. I did it in about 2 hours.
