So I recently had to weld my exhaust where the flange is at in the middle of the truck and I couldn't get the bead around the top of the exhaust since I can't get at the top very well with the welder so I'm sure there are some spots that didn't get welded there at the top. However, ever since the repair I've noticed popping noises/backfiring noises whenever I give it more than 3/4 throttle. Could this be from the exhaust not being welded all the way? I never had it happen before and I've fixed this exhaust twice now with it never doing it before. Could I be overlooking something? Check engine light is on but it has been on for an evap leak (bad charcoal canister) which I have a scanner and could check it if needed. Any thoughts? Been thinking about cutting it off at the weld and just getting a thrush or flowmaster muffler put on. Basic info is 99 2wd, 3.0 flex fuel, auto trans, 124,000 miles, new spark plugs in october (didn't do wires though), new t-stat, ETC sensor, cam synchro, IAC, ignition coil, and i've cleaned the MAF sensor. Truck idles perfectly around 900 RPM with no weird revs or drops while idling. Any ideas?
