So this past weekend I roll to California to pick up some interior parts for the DA. When I arrived at the hotel the car was purring at 800rpm. It rained all night and the next morning when I get on the road the car was idling high and was jumping up and down between 1000 and 2000rpm. After looking through everything, I came up with a guess that the TPS sensor has moisture in it. I'm back in Vegas now but it's raining over here also. I figure I was going to wait until it dries up. The TB is off a 90 intake manifold. The way it performs now, still idles between 1000 and 2000rpm, and when I let off the gas pedal, instead of a smooth decline it kind of cuts off then goes down. So there is sort of a jerk a second after I let off the gas. Mechanically everything seems correct. As far as electronically, I'm thinking moisture.

 

sounds more like IACV than TPS.

i had this same problem when my tps wasnt adjusted to the right voltage so it could be the tps
