350 TPI issues... yet again.

https://www.youtube.com/watch?v=yL7b...ature=youtu.be

A month or so ago i replaced all injectors with 22# bosch III's due to a stalling when slowing down/stopping and rough idle issue. ran great for about 50-75 miles then this new issue arose. rough idle. will usually die upon first start but on second start will stay running. sometimes will slowly die out on its own while idling. TPS is good at .54v. new IAC valve. new injectors and fuel filter. recently noticed a slight white smoke out of primarily right exhaust pipe when warmed up which you can see in video. also today i took this picture of what came out of the exhaust. after shutting engine off, smoke slowly continued to seep out of the right exhaust pipe. fuel pressure remains at about 34 psi idling.

Could it be a plugged catalytic? Are you cat(s) original?

check your fuel pressures, my guess is a failing fuel pump or bad regulator
