hey guys, I thought that I was really doing well, but now that the weather has turned a bit colder there is a new development. My turbo that i'm finishing up has started to kick and buck whenever accelerating. the car idles perfectly, no problems there. however, it goes nuts when i try to accelerate. It jumps and kicks. I've searched for a vacuum leak somewhere in the turbo tubing and all that and it is all nice and tight. no leaks. I put supposedly new fuel pumps on 6 months ago, however, the main pump is still reallly noisy. the in tank pump is working correctly and pumping as it should. Think that i got a faulty main pump and it now refuses to pump enough fuel when taking off?? thats my only idea here....suggestions are very welcome. THanks in advance guys
