P0442 on 99 Silverado (5.3L)
I have a 99 z71 silv. w/a 5.3L automatic. I have been popping code P0442 on this thing for a while and it is starting to anoy me.
Can anyone give me an idea as to where to look to fix this problem??
(P0422 = EVAP Emm. Control Sys Leak {small})
Also, it has 131,000 + miles on it.
THANX

That was first thing I did...In fact, I went and purchased a new Locking cap since I live on the Gulf Coast anyway. (still don't trust the out of towners)

Cap would've been my first thought (b/c it's easiest to check). Check out this link to get a general idea as to what's going on with the EVAP system, and what to troubleshoot:

I went to Advance Auto Parts and purchased the Actron OBD II so I could clear those little anoyances, but when it started to occur weekly, I thought I would check with everyone and see what they think.

How much would a new cannister cost??....a buddy of mine that used to be a mechanic before joining the military suggested replacing that due to the mileage on the vehicle.
