The TPS on a 89+ is different than a 86-88.
Does anyone know what pins on the 6 pin connector to test using the ohm method?? I want to set it, and I want to see if there are any bad spikes on it. The car has a prety rough on-off accell/decel during cruising... can't see it being anything else....

Also, does anyone know what could be the cause of a low rpm stumble?? If I hit the gas hard between 1000-2000rpms it will stumble for a split second (about .25-.5 sec) , then be fine, if I press the pedal slower, it's alright, only when I hit it hard. (any gear, but only that rpm range) My entire ignition system is brand new...so is the fuel filter.

Any ideas????
