My problem just started yesterday, and had the Cat removed, It was cloged, I thought that would solve the problem but it did'nt it still seems to idel @ 1200 rpms to 2000 it just bouncles back and forth which is too high. I cleaned the throtle body which was dirty, and it still doing the same, I was woundering if i had someone run a (code read.), and tell me if it a sensor?

Thanks for the Time.

did you put the 2nd o2 sensor back in?

Did you replace your old cat with a new one?

I never took the sensors out, was'nt sure which one to replace. and no i removed the cat completly.

the problem started yesterday and the first thing you did was remove the cat?

Please step away from the car. seriously.

Check for a vacuum leak first. check the Tps and the Iac.

Well too me the cat is nothing but a bunch of Political bull S---, and matter of fact i got it running very well after checking about all the sensors.......
