hey guys,
took my car to get fuel in the morning yesterday, then washed it. ready for heathcote drag day. we left for the hume highway at 7.30, the car got to the servo fine where we met up with the rest of the cars attending. when we left i started the car all was ok, was travelling down the highway at 100Kmph, then all of a sudden felt the car not shaking but more like a shutter sort of like when you are about to stall it in a manual but all the time...when i accelerated the car would go nowhere untill the turbo kicked in then it JUST dragged the car along...we stopped at a safway on the side of the road, and i turned the car off and back on, and it still done it...i looked under the bonnet and everything seemed ok....i als checked for boost leaks using my gauge, and vaccum and boost was fine...i then turned the car off, left it for a bout 5 mins and turned it back on and it was FINE??!! i still didnt trust it so i left it there all day and went to the drags without it. i came back later that afternoon to grab it and it started fine, drive 50 mins home fine and now runs fine...i cant fault it now??
the car also sort of missfires when i put the foot to the floor at 5000 rpm, but the revvs still keep climbing like normal??? i changed the coilpacks and that helped a LOT, but it still does it under full throttle...its not like a missfire but like a stutter??
can anyone help with BOTH these problems???
cheers!
