I have this problem with my 85 22re motor. I have changed spark plugs, wires, cap, rotor, fuel filter, and fuel pump. I have read couple of other similar topic and everyone sugggest to change and adjust the tps. I have read the hanes manual and to adjust the sensor is by inserting the feeler in between the lever and the stop screw (I don't get it). I have the same problem like silver did and he adjusted his tps. I also found that it had only one screw mounting it could that be the problem. Please any info would greatly appreciated. Thank you.
