My GTP has 128K on it and I just very recently found out about supercharger oil maintenance. I'm unsure if mines ever been looked at and wanted to know more about it and possible warning signs of being low. Thank you!

The dealership wants $910

When I am driving down the road and I get on the gas the car shakes. If I keep on the gas the check engine light will flash. I've already replaced the spark plugs and wires. This occurs all the time. Also I've notices lately that when I start my car sometimes it has problems starting. It'll idle rough, bog down and sometimes die. Other times it'll fire right up. I've replaced the battery and checked the alternator. It almost seems like it's not getting enough gas to compensate for the power the car needs. Help please.

My car has had a misfire for a while now. I have taken it to shops and they keep changing the spark plugs, wires ect. The last time j was at one they told me it was an electrical problem. I have a recall for my ignition key that I have an appointment for to get fixed and am now just getting around to it. Could this be why it has had the misfire?
