Hey all,
I've been documenting when I've gotten a CEL (same P0442 vacuum leak code each time), and I just got another one within a month. Well, my truck has been running like crap for a while now, and so I'm concerned as to what exactly is going on.
My main questions: Can the cause of the CEL and same code be cause for the truck to run like crap? And if so, what, exactly is going on?
I'm not going to clear the code this time. Instead, I'm going to take it to the dealer while the code and CEL are present. But I'd like a sense of what can be going on here to cause the constant CEL.
I've been led to believe that the gas cap can be the cause of this code (P0442, I think it is). But would that also cause a chugging sensation on deceleration (between 40-25 mph)? For the record, in that mph range, when coasting down through that speed range, I get the sensation you might get in a standard-shift car when the car is in too high of a gear at too slow or a speed, when the car may start to buck. The fact is that I don't know if the issues I'm having are all related, or if some are tranny issues while others are engine and/or drivetrain issues.
I just want to be armed with some more info before taking it to the dealer. As you can imagine, I want the problem(s) fixed the first time, and DON'T want to hear that they just cleared the code, and that they couldn't replicate the problem(s).
If anyone has some more insight into a reoccurring CEL with the same P0442 code, and this chugging/bucking sensation, I'd love to hear about it. It's driving me nuts. (If the low-speed bucking sounds completely unrelated, I'll take any insight into that, too.)
Thanks!
