I will start by saying i have searched for similar problems and have done the fixes for those problems and it hasn't fixed my issue.
I recently got a 90 Eagle Talon Tsi AWD and for the first week or so of having it i drove it fairly regularly. Recently i went to go overtake someone and when i was accelerating the car made a sudden strong jerk. Later I tried to see it i could cause the issue again on purpose by doing some full throttle launches. First gear went though fine, but then it second and third gear it had this hard shake at about 4500 RPM. Maybe forth gear as well, but i didn't want to go that fast with what ever issue that my car may be having.
To help clarify this is not a gradual shaking like wheel balance or alignment. it is a sudden hard shake like if you where push starting a car in first gear, though i don't know how many of you people know what that is like, i didn't until recently when i had to help my brother.
I have already cleaned the MAF sensor, replaced the fuel and air filters, and checked the spark plugs, which looked fine and gaped properly. When it shudders there is not check engine lights flashing or anything. I think it might be something to do with the turbo letting go or something but i don't know if that would cause such a violent shake.
My car is basically completely stock, as in no aftermarket mods, just it has 130,000 so obviously a few parts have probably been replaced.
PS: I don't know if this is related to the issue but one out of about five times i start my car it has a hard time holding an idle.
SOLUTION: For those who may have the same issue. Once I installed a real boost gauge i saw it was boosting too high for a stock turbo set up. It was a fuel cut issue caused by the hose in not connected to my blow off valve so it wasn't releasing the pressure.
