HELP - Car not accelerating and not coding any issues
My car 2009 G37x has been randomly not accelerating. I have had it to the dealer twice and been told they cannot recreate the issue 😩😩 The first visit they recommended a fuel injector service that I agreed to but that was just a routine mtc recommendation and not an actual fix since they could not recreate the issue I had while driving. The morning before I was headed to the dealer for the service it started again and would not accelerate past 20. I was able to make it home slowly and park it but had it towed to the dealer (because I did not want to mess anything major up-but I bet if I had it would have driven fine) to only be told they still could not recreate the issue.
Here's what I know:
Here's what I know:
- Car runs fine and only has the issue intermittently
- I smell gas Oder outside the vehicle when this happens but there are no leaks
- Car is not jerking when trying to accelerate...it's just will not go past 20 and at times 40
- Car is not giving a code when hooked up to diagnostic
- I have not done fuel service yet because dealer now wants to recreate the issue but cannot

Possibly a vacuum leak. When I had another car with a vacuum leak, it lost a lot of power and shook.
Another thought, bad coils, perhaps oil got past the spark plugs, had that happen one.
Third, the dreaded rear valve issue.
