Gut my 2 Cats

[fastmark]

This for Driller or anyone else. If I gut the two cats will the lack of them put the ECU in a limp mode? or just show a cel ? I would leave all 4 sensors in. What would you suggest? Mark

You may get a CEL. I do not know of any emissions check that would cause limp mode.

I never got a CEL from eliminating the cats and AIR system in my '96.

You will get a check engine light unless the rear sensors are removed in the tune or MIL simulators are used.

Why are you doing this anyway ?

I would suggest leaving them alone. The only thing you'll gain is a smelly car

I just gutted the cats on my 94 ford taurus wagon. Its my work car it was getting 13 miles to a gallon and sluggish. Mileage is up to almost 25 miles to a gallon city highway. Its a 3.8 and the temp gauge has been dancing around for months. So i figure before i junk her i might as well save on gas. It is smelly as has been stated smells like a 60's.70's car. No CEL but its OBDI not OBDII you won't get away with it on OBDII.

I think it depends on the vehicle. I ran catless on my jeep when I went offroad (welded up flanges to make it easy to swap out after nuking two cats on the rocks), and didn't get a CEL. It was a 97 (ODB II).

Temp gauge and low mileage makes me think the cats were plugged

I think PETA is going to come after you for that thread title

Me thinks he thinks they are plugged, which would demand something is done before other bad issues arise.
I would suggest a full exhaust upgrade with cobra manies, time to hit the stang boards.

Smelly car......thats funny
