good luck.
i think, it'd cost you less to rent a truck, than to take chances with this one.

 

How many miles on the transmission? I think it may be on its way out the door.

 

BTW, e-hall,welcome to CF, and good luck on your trip. Hopefully it'll straighten out and fly right.

 

UPDATE..... i took it for a 600 mile roud trip vacation to Island Park Idaho(yellowstone). Did great for first 200 miles had all the power i wanted then all of a sudden on the freeway (no hills just flat) it jerked and lost power. Pulled over let it sit for bout 5 minutes. Took off and made it the rest of the way no prob. And climbed a hill going from 4500 ft. to 8200 9 miles long tore it up goin 45-50 pmh the whole way


Will a bad catalytic converter cause a sudden jerk and a MULTIPLE MISFIRE on the computer?

 

While reading your symptoms, my first impression was catalytic converter. However, the sudden jerk and misfire's have me scratching my head some. I'm still leaning towards a malfunctioning cat converter as the underlying issue.

 

So here is a update on my POS. It is getting worse and worse can barely get going 60 on freeway takes about 5 miles to do so. SO i broke down and finally took it to the Chevrolet dealer here in town and they diagnosed it as a FUEL PUMP going bad???? just replaced with a New one year and a half ago and i thought if fuel pumps went bad they just went bad not slowly get worse and worse??????? Another question i have is Has anyone ever heard of buying a faulty fuel pump and going bad really fast? Thank you for all your help

 

is it an aftermarket one or OEM?
I have seen lots of stories in this forum about how auto zone or who ever's part just don't hold up to the factory replacement parts, in this case there is a reason why they cost more, and on PIA replacement parts its worth paying for the good stuff
