after I did a tune-up on the motor (plugs and wires )
I went ahead and cleared the codes, after about 4-5 days it came on again, this time with just a code of the po430 catalyst system below efficency bank 2.
Is there a good chance that it might be a vacuum leak, o2 sensor, or is it just the catalytic converter getting worst? I would hate to replace a converter if that might not be the problem. I need help wondering where else to start, to narrow it down.
I also drive round trip to work and back 104 miles a day 5 days a week, is this going to hurt me worse?
it does not over heat w/ temp gage and gas milage has not really changed or dropped. When at a stop idle I can watch rpm gage run at 700 to 850 rpm and jump up and down about a 1/4 of a 100 on gage and sometimes feel a slight miss, worse when a/c is on.
have the same problem?
