About a month ago my WJ threw a P0443 code. When I rolled to a stop the jeep would idle very low and sometimes die, so I replaced the evap solenoid and believed that solved the problem. A few days later it started happening again, and I noticed it only happens when I am at or below a quarter tank of gas. Seems it might also be related to the heat, but I'm not to sure of that since it's been in the 40's for the last few days. What else could be causing this issue? Any ideas are appreciated.
