well the other day my car was having trouble when trying to maintain certain speeds, i checked the codes and it said the problem was the narrow band tps, BTW my car is and 89 gtu. So i figured i had moisture in it, i blew it out with compressed air and took it for a ride, no more trouble, so i got home and reset the comp. so today i was bored and i checked the codes, now it is saying that both the tps's are bad, wtf, car does run a little ruff, i disconnected the tps's and started it and it seems to run the same with or without the sensors hooked up. So what do i do now? look for new ones or what?

 

Try spray contact cleaner first.

The Home Depot electrical Dept has CRC QD contact cleaner.

Spray it in the plunger sleeve, work it in, blow it out, repeat.
