Hi, my idle has increased to 1200rpm, and sometimes climbs as high as 1400-1500rpms:blink:, im aware this is a symptom of boost leak, and a major one at that, but in checkin half a dozen times with no findings, im at the stage of pulling out my hair:(, just want to know, can anything else cause this problem.

 

i have checked all small boost hoses.

all intercooler connections, and inspected the intercooler for damage, and i have drawn a blank, all advice will be much appreciated:)

i had exactly the same thing, mines a na but identical symtons. i found a few on here but with various awnsers, i unscrewed my tps, then unplugged it, sprayed elec contact cleaner in the plug, then 3 in one oil on the springs in the unit and the main tps part in the housing, put it back and is now perfect. ten min job, worth trying!

yeah guru done the reset first, still evident, and stays the same when it was warm,, i then moved on to the iacv, listened if it clicked when the engine was shut off. which it did, so it was operating, and the resistance checks drew a blank.

 

i then[crude] i know tapped it with a screwdriver, to see if it was sticking, hopin it may loosen it, but no change.

 

 

onto the tps, but finding the time is a nightmare lol, thanks for your help gents, will update.:)

 

the iacv check, was found on max-boost.com not sure how correct it is though, so was worth a try
