Whats up everyone Well i had my exhaust done 4 months ago. I did 2.25 inch piping with doug thorley headers, aftermarket cat, and a flowmaster 60 series. I had an exhaust leak. Engine gave me egr and o2 sensor codes. Turns out i needed the doug thorley gasket. Took it to a shop this weekend. They did the gasket, turn down before the axle, replace some brass fitting from a fuel leak from one of the injectors. No more exhaust leak. The exhaust sounds 10 times better. Driving it home from the shop no problems. When i went on the off ramp from the freeway i took it off of 5th gear to start slowing down. I was going about 50-60mph and the engine just died on me. I started it no problem went home. Took the truck out for a spin to see how it felt and it went smooth. But the ln it shut off on me again and i couldn't get it to stay on unless i gave it gas. Drove it home not problem. I got it on the drive way and kept reving it and it stalled out. Clean the throtle body and intake it worked fine until yesterday coming off of the off ramp on neutral it stalled out. Turned it on drove home good. Brought it to work today and it shut off on neutral while i slowed down for traffic and once again while i slowed down on neutral to merge onto another freeway. Idk where to begin. I changed out the fuel folter for the first time about a month ago. Any suggestions???
