Engine trouble!

So this is the 3rd time in the past month my Service engine Light has come on. I've pulled the same code off the car twice. (the other times I haven't checked it) I think this is the same issue it has been having since about 25,000 miles. The car now has 50,900 something.

Background info:
I've taken it to 3 Ford Dealers and they all think I'm crazy and they say well your just not used to the Fly by wire system on this car, or well there is no code. Finally for $100.00 they re-programed the computer since it had to be done to before the PreimumCare (Ford Warrenty) would pay. Well that may have fixed it for sometime, but it keeps hapening.

The problem doesn't seem to occur as much in the winter, if at all. It happens in the summer and Fall. I notice it on warm days Air Temp of 80+ and if I have used the A/C, or if I have gone through the touchless car wash and sometimes if it rains- only in the summer and fall.

When it does happen the car has a hard time acclerating, the RPM's jump, and the transmission really clunks and shifts real hard.

Lastly the code is P 2135 and my sacn tool reads Throttle/ Pedal Position Sensor/ Switch "A"/ "B" voltage correlation. I pulled off all the freeze frame data as well.

Anyone have any ideas on how to fix it or what is causing this?

Thanks!

It doesn't lag. It just jumps the RPMs and clunks and shifts real hard.

No not yet. It could be I have 3.55s no clue who did the install. Would that cause a Throttle position sensor voltage correlation error?

Could be, but again is kinda weird . If it was that the timing would be affected as well, causing ur car to act weird having from high rpms while idle to not even starting

When u got the car already had 3.55s

Hmm. I'm bound to fix the problem eventually. It had 3.55s when I bought it. I think this is why owner #1 sold it.
