flippu10 Posted October 10, 2005 Posted October 10, 2005 I have noticed that the idle goes up over 1200 or so rpm momentarily and then comes back down in both Drive and Park position. Sometimes when it goes up, it kinda lurches the car forward, when in Drive. It's been occuring more requently and cycles up and downwith less time in between normal and high. It used to not occur as frequently or the time in between normal and high is not quite as close. Anybody have any experience in this. The car is tuned up regularly. I recently just replaced my PCV valve. This problem has alsways been there though, ever since I can remember. The car has 176K miles on it. Appreciate any insights.
Toysrme Posted October 10, 2005 Posted October 10, 2005 Clean the idle valve on the back side of the throttle body. You might as well clean everything there, idle valve, throttlebody, egr valve. You can pick up 5-10bhp to get back tos tock power by taking the entire upper intake air chamber off & cleaning the SOB. The intake cakes with carbon from EGR & it impeads the flow & you loose power.
flippu10 Posted October 10, 2005 Author Posted October 10, 2005 Thanks, Toys. I'll do that. As I was searching for posts before I posted this, I saw a post that has a pretty good description and pictures of how to clean it. I'll use that as reference.
xxxavier2k Posted October 12, 2005 Posted October 12, 2005 Kinda sounds like your intake hose (accordian hose beteween maf and throttle body) is cracked.
