It sounds like the only thing you haven't done is check the oil dipstick tube and replace the gas and oil cap. The oil dip stick tube sometimes can develop a crack and be tough to pinpoint.

I am having the same problem chasing a similiar problem but with a P1124 and a P1126.I too changed my AOS to the new type with a new "j" tube.I sprayed starting fluid on all joints while running hoping that the engine would sputter and it didn't.I will get a fresh can of starter fluid tomorrow and will try spraying gas and oil cap while running and also the oil dipstick that someone suggested to you.I thought this problem was fixed until a mile from my home after a 25 mile trip.

The starter fluid works on vacuum hoses and connections before the fuel intake manifold (pre-spark plug.) It is not advisable to spray fuel or oil caps or dipstick tube as nothing should happen.

I have been reading the vacuum canister has a bad track record.It has cracks that show up when pressurized under water .I am considering purchasing a smoke machine when the price is right.Any thoughts?

Yes, a smoke machine is the preferred way to go. A good Indy or shop should be able to do this locally and reasonably. If you end up purchasing one yourself and doing a DIY, let is know. A good write up will be very helpful!

Good luck!
