I have had this pretty damn annoying problem with my svt where in 1st and 2nd gears (rarely 3rd) when I press on the gas or let off, the car jerks and makes loud clunking noises. It even happens when I only feather the gas pedal.It feels like the engine is moving around, so I am guessing its the motor mount inserts. I have decided to buy new energy suspension ones. How many should I get? Should I just get however many (3 or 4 I'm guessing) of the exact same type, like the ones that cost around $18.00 from spmotorsports or cta? One last thing, what's the install like, should I have a mechanic do it for me? Thanks.
