richarde7927 Posted March 19, 2011 Share Posted March 19, 2011 Before i have a good look at my supra has anyone got any ideas on this . I have had a misfire sometimes at high revs 5k to 7k it does not do it all the time ,lets say out of 10 times i drive it ill get it once , its not boost/ fuel cut as i have the boost controller set at 1 bar but if i set it to my 1.2 bar setting it real does not like that , when you start the car from cold it holds back to just untill you have been driving it a minute or so . Im think plugs or coil plugs as i have read they are commen problems , Any help would be great . Rich. Link to comment Share on other sites More sharing options...
FOSTA Posted March 19, 2011 Share Posted March 19, 2011 Ive just fixed mine after mine was missfireing under load around the same revs as yours! after changing the leads, dizzy cap , rotor arm, plugs and gaps. it turned out it was the coil. mine is NA-T tho and it didnt do it before i turbod it so it was just starting to brake down under boost! i can see by the pic yours is the tt but hopfully this might help a little ;-) Link to comment Share on other sites More sharing options...
jevansio Posted March 19, 2011 Share Posted March 19, 2011 Plugs or coilpack connectors would be my first line of attack Link to comment Share on other sites More sharing options...
Nic Posted March 19, 2011 Share Posted March 19, 2011 If it's intermittent then the most likely cause is the coil pack connectors, they become brittle and break over time from the engine heat. See refurb guide HERE Could also be worn/wrong heat range spark plugs, but these would usually cause a constant misfire. Link to comment Share on other sites More sharing options...
