I got a P0455 code Evap emission control system Leak (Large)
Other than checking to make sure the gas cap was on I haven't done anything yet, so don't go crazy with detailed explanations. If I get stuck, I'll let you know.
On Thursday, I plan to have my trans serviced on my '98 3.8 windstar. 133,000 miles, so while the van is up on the lift, I'll take a look at the hoses, and connections, from the gas tank forward.
Recently I noticed that the trans did not seem to be acting quite properly, maybe shifting a little firmly, and perhaps stuttering in and out of overdrive, just ocassionally. I was thinking that it was about 15-20,000 miles overdue for a service, and planned to get it done soon, but this made me make an appointment for Thurs.
Today, the shifting was a bit more pronounced, and I am hoping that I didn't wait too long. Also the CEL came on. So when I got home, I pulled codes, not only did I get the P0455 code, but a P0302 missfire on Cyl #2.
Of course, the cyl #2 is almost as difficult to get to as Cyl #1, so I am not happy with that missfire code! C4,5,or 6, would have been much better

Oh yeah.. murphy's law strikes again!
So what it comes down to, is that I may have been interpreting weak firing of cyl 2, with an ocassional actual missfire as a trans issue.
So here's the plan. I'll have the trans serviced, and look for broken hoses to the Evap emission control system.
Weather and time permitting I'll check to make sure that wire to cyl 2 is tightly connected to both the plug, and the coil pack, and if tight pull the cowel, and the plug, and check the coil pack.
gotta run
