I need a little help working out a problem i'm having with it. The other day, for no apperante, the car wouldn't start. Finally after about 4 days of checking things over I got it started, it was getting plenty of gas, plenty of spark, plenty of air. Now it won't idle right, after the engine warms up it still won't idle without the choke being on.
I walked behind the car and noticed the exhaust puffing real hard, but the engine seemed to be running fine. Do I have a clogged cat or muffler or could it be something else.

Thanks Josh

 

clogged cat is a high posablility

 

How hard is it to removed the cat and where exactly is it located. I'm not really familiar with the car yet. I'm planning on just gutting it.

Thanks
