Rico2006 Posted December 6, 2006 Share Posted December 6, 2006 Hi Guys., Hope someone can advise on how to sort this: I have a 93K TT Auto J/Spec. Currently it has a Blitz SUS ( yes, i know they're crap ) HKS SSQ, Full Decat ( 1.1 Whifbitz Decat and restrictor) THor FCD , AEM Truboost ( soleniod not connected) Just taken it out on the Track and its starting to 'judder' in the engine (ie, not smooth acceleration ) at around 100 - 120 leptons. Its not fuel cut as no warning lights on the dash. Could it be the plugs (standards still) or maybe the fuel pump ( stock) ? Any other suggestions? edit: Boost is around 1.10 - 1.17 according to the AEM. thanks Link to comment Share on other sites More sharing options...
Jake Posted December 6, 2006 Share Posted December 6, 2006 Start by checking the plugs. You say they're standard but you should be using colder than standard plugs at the boost levels you're talking about. I'd get a set of NGK BCPR7ES in there ASAFP. Should only cost you about £12 for set. About 0.85mm gap seems to work well. Link to comment Share on other sites More sharing options...

Paul Whiffin Posted December 6, 2006 Share Posted December 6, 2006 Could be plugs, first place to look. While your changing the plugs check the coil pack connectors, as the cars are getting older we are getting more and more of them breaking up, got loads in stock if you need some. If not could also be a coil pack itself although this is very rare on Supra's. Link to comment Share on other sites More sharing options...
