Took car out for a drive tonight. Developed and intermittent hanging idle (2000ish rpm). Noticed if I got out and banged on the TPS sensor with a screwdriver or ratchet it idled back down. Can the TPS in these cause a high idle condition? My first thought was the shit quality Pro Product throttle body was sticking but playing with/opening and closing the throttle made no difference.

Also can someone please remind me if the low coolant idiot light in 99-04s is tied to anything besides the stupid floating in the coolant tank? I don’t think it’s tied in to fans but would love someone smarter than I to confirm.

Thanks.
