big t esc cos,ahmed st2 usual greens pump 3 bar etc, itll run perfect till youve been cruising at around 50-60mph, for a while then it staRTS to jolt and misfire like its overfuelling,you then have to stop the car as its undrivable and the rev counter goes ballistic and the engine dies,try to start it and it stinks of fuel,but this is the interesting part ,if you leave it to cool down for 15 mins its perfect again for prob another 20 miles or so,ive changed nearly every sensor on the car,all the ignition components etc,that why i wondered about the lambda?
