Ernie Panks Posted January 26, 2007 Share Posted January 26, 2007 Spent all last night trying to trace the fault and came up with nothing. IACV doesn't seem to be a problem, it's moving freely and does what it should. What else should I be looking at/for? Help!

oilyhands Posted January 26, 2007 Share Posted January 26, 2007 Try the connection to the throttle position sensor , sticking throttle and look for air leaks.. Oily Link to comment Share on other sites More sharing options...
Ernie Panks Posted January 26, 2007 Author Share Posted January 26, 2007 Thanks Oily, still revs like buggery when throttle is shut. One thing I did notice is it sometimes revs to 3K, you can blip the throttle and it'll die to 1800rpm straight away? Did have a look around for air leaks , but couldn't find anything obvious. I'll keep looking! Cheers, Ernie visit Carrotland.co.uk Link to comment Share on other sites More sharing options...
oilyhands Posted January 26, 2007 Share Posted January 26, 2007 An engine cant rev to 2000 without air, it will be coming in via a leak, a sticky throttle or the IACV. To test if it is a leak, with it idling at 2000 take off the airfiler and block the TB entry with your hand, if the engine stops then the air is coming via the TB entry and could be the TB or the IACV. If the engine still runs (albeit slowly) then it is an airleak. If the engine stops, start it again and this time picnh the IACV hose until it is effectively closed, if the engine stops then it is coming via the IACV, either because it is stuck or because the ECU is confused over something. oily Link to comment Share on other sites More sharing options...
Ernie Panks Posted January 26, 2007 Author Share Posted January 26, 2007 That's a good plan Oily, I'll give that a whirl, thanks very much. Ernie visit Carrotland.co.uk Link to comment Share on other sites More sharing options...
Nifty Posted January 26, 2007 Share Posted January 26, 2007 Ernie, Mine's done this a couple of times. The first time I simply reset the ECU and it disappeared. the second time this method didn't work, I looked at everthing I could think of and drew a blank ... it then stopped doing it of it's own accord ❗ ❗ *confused* Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
