Guest cabbyxgirl Posted September 6, 2009 Share Posted September 6, 2009 Hi everyone ive got a mk4 xr3i cabby with the efi engine. When i bought it a couple of weeks ago it was running a bit lumpy at lower revs and was kangarooing and occasionally stalling. I did a service changed the air filter and spark plugs, the ht leads looked fine almost new and the problem remained so i put in a bottle of injector cleaner, no change. So i changed the idle control valve for a brand new item and still it kangaroos at lower revs. Ive run out of idea's now i cant find any split air pipes either. oh and i have unplugged the battery to reset the ecu too. Has anyone got any other ideas for things i can try? Your help is much appreciated x Quote Link to comment Share on other sites More sharing options...

Guest suffolk04 Posted September 7, 2009 Share Posted September 7, 2009 try disconnecting the throttle position sensor and then road test, mine used to kangeroo and cut out, i changed leads,plug,coil,map sensor and idle control valve costing me a bit,turned out to be the tps.
