Ok as u can see by my post im looking for a tps , BUT i was reading on here with other peoples idle problems and I dont see the exact same thing as mine. So here goes

99 ex 153k mi and low idle, and very very low w the a/c on.... almost cuts off at stop lights. Is it the tps??/ I was kinda assuming it was! any other suggestions? othere then that runs good! Could a cleaning do anything?
