rob2.2 Posted April 28, 2011 Author Share Posted April 28, 2011 it does it from cold, will try throwing a set of spark plugs at it, the car has uprated ht leads fitted so i asume there ok. Quote Link to post Share on other sites
rob2.2 Posted April 28, 2011 Author Share Posted April 28, 2011 new plugs fitted and not a blind bit of difference, stalled twice at junctions on way back and still a miss-fire/hesitation at 2-3k rpm after changing them Quote Link to post Share on other sites

daz gt turbz Posted April 29, 2011 Share Posted April 29, 2011 just a thing to check for free is the earth on the ignitor, mine had a dodgy one and played havoc with the car. i took the ignitor off, cleaned all the mounting points to the bracket and also made a little earth strap to the bulk head. after doing this it was absolutly fine. like i said, its worth a try as it costs nothing to do!
