Since I stored the car I have been having a bunch of problems getting it started. Once I do get it going it misses a bit and I get a lot of popping out of the exhaust. Also I noticed that the oil pressure bounces a bit at idle, it never goes below the half mark on the gauge but it moves quite a bit between there and the 3/4 mark. Could the miss be causing this?

Also should I be getting a voltage reading at the connector that clips into the Coolant temp sensor? That is what was giving me trouble before.

Sounds like you have an electrical issue. Critters in the wires maybe?

Its definitly electrical, I don't know what happened but a lot of the electrical has been acting funky lately. Shouldn't be to much of an issue since I am an electronics tech.

So does anyone know what voltage I should be getting at the Engine coolant temp sensor?

The ECT mounted in the water pump is a thermistor and uses 5V supplied from the PCM. Remember it's a voltage divider circuit so it won't measure 5 volts on the yellow wire when it's plugged in. At 32 degrees F, the sensor should read 9.4K ohms. At 212 F it should read 177 ohms.

Also remember the gage in the IP uses it's own sensor and may not correlate in readings to the ECT used for the PCM.

Thanks slopokrodrigez, thats just what I was looking for.
