appreciate the input mechanic said he needed the intake gasket fixed before he could really figure out what was going on with the engine (multiple codes, and I wasn't face to face to find out what the codes were)... the cat is a quick test and costs a mere 20$ aside from this forum at least 6 people have told me they had similar issue's with the cat. (also when my buddy took it into the muffler shop yesterday they told him, after he described the problem, that the cat. was very likely the culprit)...
