Bmxblade Posted March 28, 2013 Report Share Posted March 28, 2013 So yesterday I thought I'd replace the air filter and at the same time I noticed the TB was a bit mucky so I cleaned it up with carb cleaner , I also changed the coolant and temp sensor and adjusted the throttle cable as I had slack on the pedal . Now since I've done all that when ever I start the car it revs up to just under 2k and then slowly decreases , and when ever I've picked up some speed and then stop the revs take quite longer to drop down to idle , i have taken the TB right off and gasket sealed it up an theres no leaks , it's getting quite annoying as it ran perfect before I.e 1100 on start up then straight down to 900 and revs dropped straight away , anyone had these problems?

lupoluke Posted March 28, 2013 Report Share Posted March 28, 2013 Check your servo pipe hose for splits, but it sounds like you need to calibrate your TB with vcds, how ever it will self learn after a while how many miles you done since you have had it off. Disconnecting your battery for 20 mins then running it may speed up the process. Quote Link to comment Share on other sites More sharing options...
Bmxblade Posted March 28, 2013 Author Report Share Posted March 28, 2013 Hose pipe is fine , have disconnected the battery for 30 mins also , done about 25 miles , it just strange how it was perfect and now isn't , could it be the temp sensor? I was thinking about putting the old one in and seeing what happens Also mines is cable throttle , does that still need calibrating? Quote Link to comment Share on other sites More sharing options...
