... I'm feelin' it.
The CEL light came on, on the way to work today, and doing the ignition key trick, I pulled a code 72 from the computer, which, according to my info, indicates a problem with the "Catalytic Converter Circuit."
1) if anyone can confirm that 72 = cat converter circ, I'd appreciate it
2) taking into consideration some prior problems (listed below), what are the odds that this is a wiring problem, and not a cat problem?
***the cat is virtually brand new*** (meaning I bought it this spring)
the main, braided ground strap has been cleaned
I've cleaned the other grounds & hit them with a wire brush
Most recently, with help from forum people, I fixed (probably) a bucking/misfiring/stalling problem I had (computer code 43 "Misfire").
Not long before, some trailer wiring I installed was blowing the fuse for the A/C. This wasn't entirely unexpected, b/c the Uhaul website said I'd need a stronger fuse with aftermarket trailer wiring. Switched the 15 amp fuse for a 30 amp. It still blew the 30 amp fuse a couple of times! Now it's fine, but I haven't been doing any towing since late July.
Before that, the ground wire for the O2 sensor broke off at the eyelet where it was grounded to the block. It threw an O2 sensor code, which over the course of a year, I spent roughly $1000.00 on this (for the sake of passing inspection), including the new cat which I didn't need, only to find the broken wire & make a $0.05 repair.
I feel like I'm chasing power surges all around the vehicle?
