Bought the car two years ago w/ 92K on it. Now it has 125K. The last six times I have filled it with gas, right out of the gas station, I get a dead pedal when acclerating to around 50pmh and eventually a transmission fault. Forcing me to pull over and restart the car to clear the error. I put a diagnostic reader on it and got a P2407 friction error. The local mechainc says relapce the transmission. The local Jag dealer says they won't service 10 years old cars anymore. I was thinking of changing the plugs and using some fuel injection cleaner. Any thoughts....?
