chris whotton 10 Posted June 12, 2011 ON in the vr6 today and whilst accellerating 3000 in third engine started juddering, missing and cutting out whilst coming up to juctions on tickover. Took of ISV again and cleaned but no change could it be ignition pack any ideas cheers. Quote Share this post Link to post Share on other sites
Purple Tom 0 Posted June 12, 2011 Yep, it could well be. Check the condition of the plugs and HT leads too. Quote Share this post Link to post Share on other sites
jd89 10 Posted June 12, 2011 I've got the same problem at the moment!! I've took the isv off and cleaned it out also did the same with the throttle body but still had the same problem. Had it plugged into a computer and came up with 3 problems.... Maf has limited response Lambda has limited response Engine speed sensor has no signal Might be worth having a look at them mate. Hope this helps out, Jon Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted June 12, 2011 If the engine wasnt running when you did the scan, then the engine speed sensor will show on vagcom. Quote Share this post Link to post Share on other sites

chris whotton 10 Posted June 13, 2011 Got ignition pack off cannot see anything wrong with it unless internal,seen patern ones on ebay at £70.00 might just buy it and see if that eliminates it. Took 2 torques screws out of back of ignition pack but cannot part the thing don't want to force it is it a sealed unit? cheers Chris. Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted June 13, 2011 yeah possibly, but not 100% had a similar issue myself, coming up to a roundabout and the car starts to misfire but it did pick up and be fine for the rest of the day, same happened again the other day. This morning the car wouldnt start at all. Turned out that the a couple of the HT leads were arching onto the pack. So check this to. Quote Share this post Link to post Share on other sites

Critical_Mass 10 Posted June 15, 2011 Does it idle ok? Can you get it hooked up to vagcom? Quote Share this post Link to post Share on other sites
Portent 0 Posted June 15, 2011 MAF? Coilpack? Quote Share this post Link to post Share on other sites
chris whotton 10 Posted June 16, 2011 Will this show up as fault if plugged into vagcom cheers Chris. Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted June 16, 2011 Coilpack would be a misfire and would show on vagcom if its misfiring at the point you scan - obv scan with the car running. MAF would also show on vagcom Quote Share this post Link to post Share on other sites
chris whotton 10 Posted June 16, 2011 Will mention this to my mate at vw , thanks for that mate cheers Chris. Quote Share this post Link to post Share on other sites
