Okay back with a new issue. Here is a brief shake down on what has taken place. Spun bearing so had the engine rebuilt. I then had an issue with the #4 cylinder misfiring. Had a smoke test to see if there was an internal leak. There was not one. Had a mechanic adjust the #4 to correct the misfire. Then had backfire from the passenger side exhaust that turned out to be catalytic convertor that broke apart. Replaced both cats! All has seem pretty normal but still lacking some power randomly so I change the VSS and TPS. Got some power back but still random acceleration issues. Decided to change the hoses and noticed that the passenger side exhaust manifold was glowing red. Figure the muffler was semi clogged so I changed both mufflers and still got a glowing red exhaust manifold on the passenger side. Please help cause I am really cwm8and tire!
