Hey guys so I've been having a problem with power surges in my 1994 GMC 1500. I don't know if this is relevant or not but my Cat-back exhaust fell off about a week and a half ago due to rusty hangers that broke causing the exhaust flange right behind the cat the break. I was on my way to work about 20 miles away so i pulled over and threw it in the bed of my truck and later that night (I work second shift) I welded on a new flange, bolted and hung my exhaust back on with no problems. a couple days later I started getting a power surge like my fuel filter was clogged. I first started with changing my air filter which was probably long past due because I took my truck to the dunes 6 or 7 times this summer in Michigan. the Air cleaner didn't do anything so I put a new fuel filter in it also. I parked my truck in the garage over night and it wast leaking fuel anywhere which zeros out the possibility of air getting into my fuel line. I have a couple thousand miles on a delco fuel pump so I doubt it is that. I then changed the oxygen sensor and that didnt do anything either. after putting in the new oxygen sensor i thought all was good but now the vacuum line that runs out of the back of my motor to the transmission keeps blowing off causing me to lose overdrive. It has happened twice and I put a hose clamp on it to fix it for now but I dont know if that will be good or bad considering that it keeps coming off for a reson. Is this going to be an easy fix or a trip to the shift shop? I have searched forum after forum and cannot find anyone else who has had this problem. there is about 6,000 miles on a transmission rebuild that happened back in July.
