need help with my idle, its getting worse, it goes up and down, it goes between 100-2100, this morning it cut out 4 times on me when i had to stop. idle control valve is brand new, and the tps checked out fine. sometimes when the revs go down it will flick back up and stay at about 3-4000 revs for about 10 secs, it also is kangarooing at low revs so i have to keep on dipping my revs, its doing my head in please help getting desperate

 

i'd say that you have an air leak somewhere. check your map sensor voltage at idle too

 

will do asap, cheers m8

 

When mine did that the inlet manifod gasket had gone.

 

hi, regarding this thread anyone now how to check for leak in inlet, this sound very similar to mine, revs are hunting around 650-1500 then jump to maybe 2000-2500 then drop.......
