For the past two months while attempting to accelerate, my RPM will jump to over 3 while barely pressing on the gas. This issue tends to happen more when I slow down (but not completely stop, like at a changing light) and attempt to speed back up. My car doesn't accelerate very fast but the RPM will be very high. Also, while on the highway, going a constant speed my RPM will jump up and down. I've attempted to use my autostick to get the RPM to drop back down and it only helps occasionally. I've had spark plugs replaced, a new battery, a transmission flush, wires replaced for the throttle body (they were broken/burnt), my car said it had the wrong oil in it, so I got another oil change, I've had the transmission flashed twice. I've had 5 different people/shops look at my car (including the dealership) and none of them can figure out what's causing it, all repairs have totaled over the last two months since having this issue, roughly $1,500. The issue is still happening and this is my second Chrysler 300C.
