I recently replaced TPS due to troubke code. Car runs so smooth & quiet until it is barely starting to warm up & then the idle is very rough & doent matter if in drive or park. Noticeable when car not moving. Sometimes it almost feels like it might die. But the idle isnt consistent in the rough idle part, so I dont think its misfiring. Ive checked the pcv valve by removing it & shaking it, was good. Changed air filter, checked to make sure no hydrocarbons present in coolant. Was going to clean the throttle body/intake but a friend said on mine I couldnt. Any advice on what the probkem might be? Oh and I need to replace two u-shaped rubber hoses that are located to the left of the tps & air cleaner housing hose but I dont know what theyre called. Doesnt appear to be cracked but rubber flakes right off to touch. Theyre vac hises of some sort, maybe part of the evap system?
have the same problem?
