Vacuum leak. Possibilities include the cruise control mechanism underneath
the battery (battery acid drips and erodes the vacuum line going to the
canister, causing a vacuum leak), or a leaking intake plenum gasket. If you
remove the PCV valve, and can feel a vacuum when covering it with your thumb
(especially when revving the engine), then you have a plenum gasket leak,
and will need to remove the intake manifold to repair it.
I checked the PCV valve vacuum and there is none. I also tried revving up
the engine and the air cond worked ok and I revved up the engine with it in
gear and still ok, but when I drive it, it does is almost immediately. Only
for 10 seconds or so. It's not really a big problem but just kinda
irritating and hoped it would be simple. I am going to take out the battery
and batt holder and check the hoses. I found the canister (I think) under
the driver side door with 3 hoses. 1 large one secured good, and 2 smaller
ones and one of the smaller ones came out of the boot easily. I'll try and
seal it better and try again soon.
