Car started to miss badly and run poorly overall. Had car worked on by mechanic but to no avail. Have changed all four coil packs, new plugs, one new injector, gaskets all around, cleaned throttle body, checked for intake leaks, basically the whole nine yards and it still is misfiring. Before all the fixes, the car would not even hold idle without giving gas to engine. Could not come to a stop without shutting off. I have resorted to asking for other outside opinions since I have ran into a wall and do not want to keep throwing parts at it. It now holds a steady park idle at 1200-1300 RPM and once in gear holds at 800-900 RPM. This is much better than before but now after driving car for a bit, car will jerk and go into limp mode, limiting car to roughly 60 MPH. Need advice on what could possibly be wrong.
