What causes this? Okay i thought my cat was going bad, it had this god awful buzzsaw like sound at 2-2200 rpm, but today my car at a stop light just randomly idled really rough, and then when i tried to go, nothing happened, gas was fully in and car didnt move, turned it off and back on, check gages was on, and seemed like the engine wasnt moving. let it sit for a second and it cranked over fine and i was able to pull out, but when i did the car seemed to jerk real hard (heard this is also a symptom of a bad cat) and a noticble loss in power trying to pull out in traffic., check gages went off once the car was moivng. It seems like the buzz saw sound at 2k rpm has gone aswell.. Could all this be caused by the cat?

Check gauges means it could be 1 of four things. 1. NO GAS which you should check. 2. Battery voltage...low battery or bad alt. 3. temperature was HOT as hell. 4. Oil PSI. No oil pressure.

thats the thing :\ all my gages are fine, oil pressure is fine, just got gas not but 50 miles ago (full tank), the check gages only came on once the car had stalled, once i let it sit for no even 30 seconds, maybe 10 seconds, and crank it over, it started and went fine. battery volt meter reads right in the middle, im at a loss, but ima take it to the shop that did the work on it (the day i let them do the work, is the day everything started ******* up)

it needed some welds, put new breaks and rotors on it, just simple stuff but since that day my car started acting up, they removed one of the U rings holding the exaust :\ i know that for sure, other than that i dont know what they might have done.

to update you guys, i have had the last 2 days off work and school due to fall break and was able to get to the bottom of it, we checked the cat and it was fine, checked plugs/wires they where fine, checked the fuel filter and OH MY GOD. ( i recently just bought this car off a camaro collector) and.. the fuel filter was so disgustingly clogged i have no idea how the car even drove. Replaced that and then i went to checking for the sound since it wasnt the cat, well evidetly one of the bolts had came loose on the exaust and that was rattling and making the grinding noise. Car runs great now, better than befor :S honestly i wihs i would have taken a picture of the fuel filter.

took it to my friends shop and ran a scan on it, its still throwing a lean code and after idling a bit it starts to idle real rough again, think the injectors might be clogged 
so i through some injector cleaner in there and hopefully dont have to get them cleaned.
