OK the vacuum leak didn't fix it, although it did seem to run a little better. We noticed that the wires coming from the temp sensor have a cut in the insulation & the bare wire is slightly exposed. We're gonna trace these wires all the way back & check for damage. Do yall think these small cuts could cause this problem?

i would think so. if they are exposed they could be touching something, somewhere along the line.

OK nothing we have tried has worked. Something I&#39;ve noticed is very interesting. You can drive the car while it is still running rough & sometimes it will instantly clean up like someone flipped a switch, bam it&#39;s running fine. Another thing we tried was putting the temp sensor in a cup of almost boiling water while connected to the car and running but the with the engine actually cold. It never really cleaned up all the way but when we put the sensor in cold water it got worse. So the manual says the temp sensor should be recieving 5.0 volts & it&#39;s only recieving 4.6 volts. Does anyone think this could be the problem? The manual says resistance will be lower at higher temps & higher at low temps. So my hypothesis is if the sensor is never recieving the correct voltage (too low)does the computer think the coolant temp is very low thus enriching the a/f ratio too much. Again any advice or help is greatly appreciated.
