I hope someone can help or has solved this problem before.
I am a new member. I have owned my 2003 Vibe GT since i bought it new in March 2003. It is the 1.8 l vvlt-i, 6 speed manual. I dont have to tell you how good of a car it is...you know. I have over 400,000 k on this car and I love it but, I have a problem.
The car started to go into high revs at lights about two years ago(usually in cold weather) sometimes rev up to 3500 rpm. a tap down on the gas would resolve it but it sounded and seemed dangerous. After many visits to the mechanic i still have a problem albeit much improved. It runs mostly good in the summer, but when it starts to cool off it still revs up to 2200 or 2500 rpm at lights (in neutral or with clutch in). It is definitely worse in cold weather. A tap down on the gas resolves it everytime and then settles down to 1000...perfect. Until i stop at the next light.
some of the work performed
The throttle body has been cleaned twice
fuel injection has been checked
I have replaced the idle speed module
upstream oxygen sensor
checked for vacuum hose leaks
lubricated all linkages
i have been to a gm mechanic and my normal mechanic and dont want to spend a lot more money.
it is a nuisance to tap down the rev at every stop but i am used to it.
error code was P0505 that was resolved with the repairs (almost) trouble light pops up about once a month but disappears before i can get it scanned.
does anyone have any ideas to resolve this problem?
