VDubPo Posted March 6, 2013 Report Share Posted March 6, 2013 Hi, im having trouble with my lupo, its hunting in idle with the revs going up and down between 700 - 1500, this has been the case for about a month or 2 now but today another problem has occured. its not revving propperly, everytime i change gear the revs climb stupidly slow with my foot to the floor until about 3-3.5k and then suddenly it kicks in and i speed off (if thats possible in a 1.0) and when pulling off ive had to redline it to stop it from stalling, i stalled 7 times on my 3 mile journey back from work i have read a few posts with similar problems and various attempts and fails at fixing them but there all old, anybody have any light on what will be the definitive cause of this and how to fix it. Also its blowing somewhere near the manifold which a friend of mine thinks may be a split flexipipe but this has only happened the last couple of days and the hunting in idle has been happening alot longer, could the 2 issues be connected? Please help with this, ive heard some people spend around £500 trying to solve this problem and having no luck and if thats going to be the case id be better off selling it but i dont want to see linda go.

Al3xTee Posted March 6, 2013 Report Share Posted March 6, 2013 Have you tried cleaning and resetting the throttle body? Quote Link to comment Share on other sites More sharing options...
VDubPo Posted March 6, 2013 Author Report Share Posted March 6, 2013 Not tried it yet but going to give it a go over the weekend, from what ive read im not sure this will help but its worth a try. i suspect its a mixture of air leaks, misfiring cylinders and a worn out map sensor from what ive read but this whole hunting problem seems a bit hazey when it comes to fixes, also waiting for a part to sort a problem with the pre cat lambda which may be contributing to the problem but the guy whos supposed to be getting the part and apparently "serviced" the car a month and a half a go isnt answering the phone so i may order one myself.

Skezza Posted March 7, 2013 Report Share Posted March 7, 2013 Oh, wait just remembered it's electric throttle. Hmm, not sure then. I'd definitely recommend cleaning the throttle body first, also maybe clean the egr Quote Link to comment Share on other sites More sharing options...

Adam R4 Posted March 14, 2013 Report Share Posted March 14, 2013 Isn't that guide for the likes of the 1.4s and GTi's? Because the 1 litre ones different and I'm told its watercooled... Quote Link to comment Share on other sites More sharing options...
