DodgyRog Posted September 3, 2014 Share Posted September 3, 2014 Sounds similar to mine Paul, it turned out to be a Coilpack starting to go, but was told it could just be a clip also Quote Link to comment Share on other sites More sharing options...

jcbt Posted September 3, 2014 Share Posted September 3, 2014 Paul mine was misfiring at 5k revs on Dragonball with 12 month old non oem coil packs. Changed them for proper Toyota ones and all was fine suggest try this as misfires are normally plugs coil packs or clips Quote Link to comment Share on other sites More sharing options...

Scooter Posted September 3, 2014 Share Posted September 3, 2014 Can't find it but I recall someone's actual loom in the plug area being worn through or having exposed wires...will keep searching. Quote Link to comment Share on other sites More sharing options...

Scooter Posted September 3, 2014 Share Posted September 3, 2014 I don't think it was 'that' bad to fix just unexpected... Quote Link to comment Share on other sites More sharing options...
TT Paul Posted September 3, 2014 Author Share Posted September 3, 2014 I don't think it was 'that' bad to fix just unexpected... see how it goes try coilpacks first easy to do with a meter on ohms. hot/cold temp readings Quote Link to comment Share on other sites More sharing options...
Lee P Posted September 3, 2014 Share Posted September 3, 2014 Coil packs Fit new Toyota ones. I've had loads of issues with super spark I keep the Toyota ones in stock at a reduced price Quote Link to comment Share on other sites More sharing options...
TT Paul Posted September 4, 2014 Author Share Posted September 4, 2014 well done a ohms test on the coilpack pins nothing showed. after some googling a few sites say that you won't really get a reading with a meter due to low resistance, and best to change them to find faulty unit so that will be next..
