I recently had the gas cap changed (told there was a vacuum issue) at inspection. It is very difficult to remove this new cap when I go to fill up. Now the car is experiencing episodes where it does not want to start (wants to turn over but it chugs, chokes). Once it's running, the car is fine, smooth, and with no acceleration issues.
I had another try and take gas cap off this am and it came off very easily!!! Could this new gas cap be creating too much of a vacuum while its running for long periods and then preventing it from restarting after being off for a short period of time.
I drove it for about 25 minutes, pulled into a store to shop, came out about 30 minutes later and it would not start. Next morning, started fine.
Same scenario the second time.
