Hello,
This is the first day I have visited your forum. It's already been a great help. But now I have a specific question.
I have a 94 Z28, 6 spd with 100k. I notice that my service engine soon light comes on several minutes after start-up. The cooling fans engage when the light comes on. It still runs OK and is getting reasonable mileage. But I do want to find the cause as my state emissions test is due, and this will make it fail.
My manual, and several posts I have read state that only 93 (and older?) models can check the codes by shorting the A & B pins on the 12 pin connector. But I've checked with the local parts stores, and they only have the cheap tester that shorts the pins to read on the dash.
Can I jump these pins on my 12 pin 94? If not, what type of scanners are availible for a 12 pin 94? Any idea of my problem from the symptoms? Thanks in advance.
