The car was running perfect up until this morning. I was gonna be on my way to work & I turned the car on to let it warm up like I do everyday year round. After starting her up it was normal higher idle from a cold start then about 1 1/2 into warming up the car it started to idle like ****. It sounded like a muscle car out the back of the exhaust and when I went to tap the gas to rev it up, it sounded like a lawnmower. So after it warmed up I turned her off waited a minuet then turned her back on and it was idling like crap again this time right off the bat. So I drove to work and it sounded like a damn lawnmower all the way to work. Certainly lost power too cause the RPM went high just to get up to 2nd gear. Got to work left her sitting there for a few hours. When it was time for me to go home I turned her back on and still the crappy idle, but there was no engine light on yet. When I got home she had no power to make it up the drive way. I have a steep drive way at the front. When I got to the end of the drive way I put her in park and then got out for a sec to look under the car too see if there was a hole in the mid pipe or around that area and it looked fine. Then all of a sudden I started smelling burning and then went to pop the hood. As soon as I reached to pop the hood I looked at my cluster and saw the Check engine light finally came on. Then I opened the hood and saw this light blueish color smoke coming from right behind the driver side high beam. Right between the radiator support and the radiator on the driver side. Turned her right off and went back to where the smoke was coming from but couldn't locate the source. Also the car was not over heating I watched the temp the whole time.

Any ideas? I've spent way to much money fixing and replacing **** in the engine that went bad. Now this? I think it's time for me to move onto the Integra I want. I really don't want to get rid of her but enough is enough. This car has seen the repair shop more than I have gotten pay checks every Friday in one month!

Thanks for the help.

***UPDATE***
Just got off the phone with my mechanic and he told me it sounds like the catalytic converter is clogged. I turned my car since I last posted this thread and there was no smoking coming from behind the high beam like I mentioned before. I also topped off my coolant seemed to be a little low. Taking her in to the shop once...again... on Monday too see whats the damage to my wallet.

Any of you know how much it cost for a replaced catalytic converter?

misfiring is also a good diagnosis... you would get more of a smell of gas though as some of the fuel isn't burning... check your plugs, wires and dizzy also.... this is sounding like a simple problem to fix, just finding it
