Re: Major Sputtering
Get a new aftermarket cat in there.
There has to be a cat in there or you will be screwin up the engine fuel trim values.
The cat will be a big source of your problem.
The O2 sensor system is the most important part of the emmission system and when it is screwed up, your whole engine will be screwed up and running like shit.
Get the cat in there, always fix the obvious and work from there.
