lamboyello Posted September 14, 2011 Share Posted September 14, 2011 Car was fine on the way up Sat but left JAE on Sunda at about 7:30am. After travelling about half an hour I started using the boost a bit more and whenever i got into the second turbo it was boosting fine but the car felt like it was pulling back, like spitting. Jerking. Anyone got an idea of what this problem could be, valves being sticky maybe? There was no smoke so i dont think its the turbo.

FOSTA Posted September 15, 2011 Share Posted September 15, 2011 have you got an a/f gauge? if so is it going lean or rich when it starts to hesitate? it could be a few problems really. overboost causing fuel cut. could be spark blow out etc .... check plugs and coil packs ets. so all basic stuff first ;-) Quote Link to comment Share on other sites More sharing options...
absz Posted September 15, 2011 Share Posted September 15, 2011 check the condition of the coilpack clips,misfire on boost is normally related to coilpacks due to increased current draw required to jump the spark plug gap on boost. Quote Link to comment Share on other sites More sharing options...
Bossco Posted September 15, 2011 Share Posted September 15, 2011 Sounds very much like a missfire. Coil packs, connectors and plugs are the first things I would check. Quote Link to comment Share on other sites More sharing options...
