what about the gas ? if its a couple months old it needs to be drained and replaced with drygas plus 93 octane.get a friend to spray carb clean or gas into the throttle body after u take off tube, while simultaneously cranking it dont press pedal down on fuel injected cars.juice up battery for at least a hour before.also you could unbolt exhaust before the cat or carefully unscrew oxygen sensor to eliminate clogged cat idea.Remember the majority of engine problems come from faulty electrical and intake. for example leaking manifolds ,worn maf air sensors, shotty wires or connectors.
the GM models connectors (the plugs that wires plug into) are the source of many troubles like overheating hard starting
