Default Re: New here - Experiencing some real issues with my PT Cruiser

P0441- is 90% of the time a loose gas cap

you can get an o2 sensor for $60 and only take an hour to change... The whole fuel system runs on vaccum (58 psi i think) if the cap is off/loose the vaccume cant complete and the whole system could be off (ie running rich) and caused the problem w/ the o2.

The lack of vaccume could explain your acceleration issues as your pcm is trying to adjust (add/subtract) fuel but has trouble controling it if not at 58psi.

I was just thinking out loud, sorry
