Hi all, Ok I admit that i played around with the pressure sensor and now it acts all funky. Im talking bout the one that lives under the left side of engine compartment. Scoop: The car was runnign outta steam on hills and even the slightest inclines (im talking like 1% grades!) and so I adjusted the little screw on the back of the pressure sensor and lo and behold plenty of zoom on hills, prob solved. Not quite, that car still fell a little jerky when pushing on the gas pedal ( same as before a played with the adjust screw). So I took off the sensor, tested the ohms across the two windings and both were well within specs. But I knew that the rod inside could also be a culprit, so I opened it up (against my better judgement) and blew it clean, was a little dirty inside, put it back together and now the adjustment is way off. Im getting about 20 mpg in town 25 hghway. Before all this happened I was getting 23 +/- in town, 28-30 hwy. ans smooooth. I know the poorer mpg is because I havent yet found that proper tweak of the adjust screw, but the jerking? I was thinking of buying a new one from Rocky Mountain Motorworks. Any thought to this? I am pretty sure even if and when I rediscover the exact adjustment for that screw that the car will be fell jerky on acceleration. I think, well that sensor is almost 30 yrs old, and its one moving part may very well be worn. Help.
