Car bucking in first and second

[92talon720]

So I've searched and found lots of threads suggesting a boost leak, but I just replaced and fixed my boost leaks. Now in first and second gear my car is bucking and stuttering like crazy. Once again searched but most are stuttering and hesitating in all gears, mine is only in first and second. Any ideas?

Its probably still fuel cut. Boost leaks arnt the only reason for fuel cut. Could it be that you just arn't feeling the bucking in the other gears.

Im thinking its fuel related also. You could very well be playing with fire if you dont have a way to monitor your air/ fuel with upgraded injectors or fuel pump and turbo. Is this in WOT? Guess you dont know if its knocking or not.

I should have said that I put the car back to stock for the winter... And Ive been noticing it only happens when it hits a quarter of a tank. I am positive it only occurs in first and second gear.

Some one told me to check the fuel pump and filter, so im going to do that and see if its any better, maybe a clocked filter i dont know

It might just need new spark plugs and wires, try that if they are old.

no brand new plugs and wires

Sounds like you are over boosting. I had this problem as well, only happening around 5k at WOT in 1st gear. Turned out my boost controller hose to my wastegate was cut in half and was boosting at 21psi when it was set at 16psi.

EDIT: Just noticed you said it was put back to stock, perhaps you should check the boost solinoid and see if all hoses are intac.
