Peter my 87' doesn't have an air inlet temp sensor on the intake horn like my 91. The resistance on the engine control coolant sensor was .48 ohms. I think it was the furthest sensor on the rear left of the engine near the valve cover right.

Brewtoo the voltage from the o2 sensor started at .36v I reved the engine for about 2 min and it dropped to .30v
Does the constant 92% duty cycle mean my EHA is bad or could it be that my o2 sensor at .36v is not sending a strong enough signal for it to work properly.

I wish the file 07.3-0121 Testing electrical components of the KE injection system from the CD worked for me. It seems to be missing on my CD.
Help with the numbers is appreciated.
Thanks Again Vinnie
