Q: Issues with acceleration, no gradual change of speed
Recently, my car has been very slow to accelerate. This happens when I drive uphill esspecially. The other day while I was driving, the car would stop moving right away, each time I let go off the gas pedal. It would make jerking movements when I gave it gas again, instead of slowly accelerating. After that day, it's been running fine with no issues. I was told the problem is caused by a worn solenoid purge valve. What do you think? Could that be the cause? Thank you in advance.
