Anyone else on thier 3rd catalytic converter?
 

Well Thursday my 3rd cat should be arriving for install. Just seeing if anyone else is on thiers or any ideas why they dieing quick.

04 50k miles

So far 3 dead battterys, 2 starters, 1 water pump, 1 intake manifold, 1 coil, 1 set of plug wires, 16 spark plugs, 2 cats, 2 rear wheel studs and a partridge in a pear tree.

You mentioned 1 coil... is that literally ONE coil or one set of four coils?

I agree all should be replaced if one goes. The others could be taking out your cat.....and plugs......and power.......and mileage....and engine....etc.
