My car loses acceleration while driving.
While driving long distance my car loses acceleration, i have pulled over shut it
down and restart the car, after a few minutes than it works again. I have taken
the car to the dealer and they have never heard of it. HELP!!!
Would start with easy things first such as a new fuel fliter, cleaning the throttle body, and having a look at the air filter. Since you brought it to a dealer I hope they did a scan for any pending codes or stored ones. Unfortunately they don't always show something. Without more info ideas would be just speculation but have a feeling it has something to do with electrical that would be effected by heat such as a MAF sensor (dirty) sometimes they can be cleaned with CRC cleaner. Other Ideas are throttle position sensor/throttle body or compression loss. Those are just ideas. Hopefully it's just a fuel flow issue. Would not just throw parts at the car at this point, as mentioned try some cleaning and a new fuel filter. Good Luck!
I have the same problem. Only when it is hot outside. I’ve been told transmission is going bad, BUT that makes zero sense. Had problems last summer any time it was over 90 degrees outside and then no issues all fall or winter or spring. Now that temperature is 90 and above - power loss. Yet when temperature is less than 90, it drives fine.
