When the car gets warm the revs drop and raise between 700ish and 500, then if i blip the throttle when it is stood still or raise the revs over 1000 rpm say when moving forward in traffic the revs drop right off and nearly (and sometimes ) stalls. Any one got any ideas what could cause this, the only mods are an apexi air filter and cat back exhaust...that i know of anyways as i have just bought the car.


Cheers

Chris

P.S im a noob so hey

you got a dump valve fitted ???

IF not then I would suggest cleaning the Air flow sensor.

Mine used to be exactly the same.

A alcohol wipe such as IPA would do the job ;)

Also try resseting the ECU.

Disconnect battery and turn lights on to drain all power, reconnect and go for a nice drive to allow your ECU to relearn everything. Sometimes does the trick.

This is what I had recently O2 sensor sorted it, so a clean up or replacement seems about right.
