when changing gear the revs are slow to drop,sometimes increasing slightly before dropping. Any ideas?

 

Tight/sticky throttle cable?

 

i was told it could be the idle control valve needs cleaning.Took it to a local establishment.......Big Mistake, i wont name them. They had no replacement gasket so tried super glue! no good then used some sort of sealant,it sealed but i still have the problem.

 

BTTT

 

From what youve said about the garage you used> id suggest buying a new gasket and cleaning the idle control valve yourself properly and then fitting backtogether with new gasket

very easy job to do

 

thats the plan and to keep away from them in the future.

 

A bit of info on what type of car you have is a start..Try resetting the tps.I had a similar problem after simtek was fitted and i rescaled the tps. noticed the diffrence straight away. There should be a link on sn somewhere, if you cant find it i will write up how to do it later, or someone else might do it for you.

 

04 WRX i will be ordering a new gasket and having a go myself.Now the daft ? what is the TPS?

 

Throttle Position Sensor.

 

cant find the link for the tps

 

still got the problem icv has been cleaned .If i change up before 3000 revs its fine but any higher the revs climb.I have now got Ian Litchfield on the case he tested the tps andsaid it was working fine.Any suggestions??

 

BTTT somebody must have had this happen
