Help! Need ideas on whats wrong with my car! Got a tune up on my 07 tc a few of weeks ago. New spark plugs, oil change and replacement valve cover gasket that stopped my oil leak. 7 days ago my fuel pump goes out. Replace the fuel pump car drives for 2 days before leaving me stranded. Redone the wiring harness on the fuel pump. It crank and drives but when it drives you can feel the up and down and up and down like something is blocked or stuck or in the way I'm not sure. Almost like the gas flow is there but not like it needs to be. Thoughts anybody??
