Re: 01' Taurus Sputtering and Rough Idle
To add to R.S.Logan's entry, if the coolant is shorting the signal buss for the sensors, the output could drop which will cause the return signal to drop as well. The TPS and O2 sensors run under a pretty tight band, so they could be affected first. Get the leak fixed and apply some electronic cleaner to the connections.
Did the mechanic throw a vacuum gauge on the manifold?
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
