Robboo Posted October 16, 2012 Share Posted October 16, 2012 Hi guys, got a weird issue, sometimes when I start my Zed up on cold mornings the idle will be lumpy and so will acceleration. After 2-3 minutes the engine light starts flashing aswell, If i turn the engine off and on again the problem goes. And no issues when hot? I would try getting a fault code but no idea how to get them up Anybody had anything similar? Cheers, Rob Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted October 16, 2012 Share Posted October 16, 2012 throttle body might need cleaning. could be blocked injectors, running a can of BG44k might help. or could be a spark issue, when were the plugs last changed? this are all good start points and in expensive Quote Link to comment Share on other sites More sharing options...
Robboo Posted October 16, 2012 Author Share Posted October 16, 2012 Ive only had the car around a month, and was told the car was serviced not long before. But then again anyone could say that lol. I can check the spark plugs thats a good shout. Didnt think it would be the throttle body? And could that and blocked injectors cause issues only on really cold starts?

rtbiscuit Posted October 16, 2012 Share Posted October 16, 2012 throttle body can get a bit sticky, becareful cleaning round it. if it gets nudged, it can kick a code up. something like a spray in cleaner for when the engine is runing might work best. or use a carb cleaner. lumpy on a cold start up might be spark or coil, but without being in the car its difficult to diagnose.

Robboo Posted October 16, 2012 Author Share Posted October 16, 2012 I know it is hard to diagnose without seeing what I mean or having any fault codes, just moved the car and it did it but gave it revs a couple times and it went. Very strange! Will try and get a look at the plugs tomorrow and will get some TB cleaner. Thanks v much buddy Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted October 16, 2012 Share Posted October 16, 2012 see how it goes, i'd try the BG44k as well, once you've run 2 tanks through one with and one without you'd be suprised how good it is Quote Link to comment Share on other sites More sharing options...
Dblock Posted October 16, 2012 Share Posted October 16, 2012 If you clean your TB do all the resets and idle relearn as that always smooths it out for me. Quote Link to comment Share on other sites More sharing options...
