rough idle!

I would go with IACV umm as far as it being the CAT? i would highly doubt it being that. The cat system is suppose to last the life of the vehicle but i mean don't get me wrong there is always a possibility of it actually being clogged...

im not really familiar with you guys' motors..but it should be held on by 2 10mm bolts and have 2 small coolant hoses going to it...on the backside of the the intake manifold somewhere....you undo the bolts...and spray carb cleaner in there...i even used a couple qtips on it to break up more debris...then reinstall...

be advised you will lose a little coolant and your car might take a few extra seconds to start...mine did but after that started up everytime...
