knacker Posted May 16, 2009 Share Posted May 16, 2009 Hi everyone, I have just acuired a 95 3.9 V8 Disco and it's running a bit lumpy on the hand right side of the engine (as u look from the front of the truck), Have changed plugs and leads but have noticed that the cat on the on the same side is glowing red hot after running for a few minutes. Is this what could be causing the problem ? Quote Link to comment Share on other sites More sharing options...
Fern Posted May 17, 2009 Share Posted May 17, 2009 Rich mixture on that side, i think. Distributor? Injectors? I mean it fires occationaly or simply has to much fuel. But i think it's ignition problem. Quote Link to comment Share on other sites More sharing options...
pw8757 Posted May 17, 2009 Share Posted May 17, 2009 What did the old plugs look like that side? Quote Link to comment Share on other sites More sharing options...
knacker Posted May 17, 2009 Author Share Posted May 17, 2009 Job sorted, Someone had put the leads on wrong on a couple of leads !! Had another look today and checked the leads were right, When we put the new ones on we just changed like for like and didn't think that they could be on wrong in the first place. It runs sweeeeet now not bad consiering that we got it cheap because it was running like a bag of nails B) B) B) Quote Link to comment Share on other sites More sharing options...
BogMonster Posted May 17, 2009 Share Posted May 17, 2009 Never discount the possibility that the person before you knew little difference between their posterior and their elbow...! Good result Quote Link to comment Share on other sites More sharing options...
