Defcon5 Posted March 25, 2014 Report Share Posted March 25, 2014 Could be one of a number of things, none near the gearbox though!Plugs/leads/coil pack/throttle body/EGR/temp sensor Any other symptoms? Quote Link to comment Share on other sites More sharing options...
Wee Sprocket Posted March 25, 2014 Report Share Posted March 25, 2014 Any codes on the ecu?WS Quote Link to comment Share on other sites More sharing options...
danoid Posted March 25, 2014 Report Share Posted March 25, 2014 Most likely a vacuum hose got disturbed during gearbox change Quote Link to comment Share on other sites More sharing options...
Defcon5 Posted March 25, 2014 Report Share Posted March 25, 2014 Wouldn't that affect it before it warmed up though too? Quote Link to comment Share on other sites More sharing options...
gnilleg Posted March 26, 2014 Author Report Share Posted March 26, 2014 Getting no codes through from the ECU.Once the temperature has reached about 70 the engine starts the pulsate or chudder intermittently. The revs stay constant, and the engine it fine once its moving.Ill get a video up asap showing the problem. Quote Link to comment Share on other sites More sharing options...
