To break this down to the lowest level, you took your ZJ somewhere ("they fixed the exhaust"), and now you have a CEL and multiple codes. You do the math.
Is clearing the code necessary? Will it just go away if the problem goes away after a period of regular driving?I'd also be tempted to just clear the code, then start it and let it get completely up to temp a couple times to see if it persists.
Some conditions will cause the CEL to go off when the condition no longer exists. Others will persist for a specified number of key-on-off cycles (where the engine runs for 3-5 minutes I think). It's easier to just clear it and see if it comes back than to wait for it to go off.Is clearing the code necessary? Will it just go away if the problem goes away after a period of regular driving?
Take it back to Pepboys and have them fix what they broke.scrap the zj
That's what popped into my head, too. My buddy has used spark plug "no foul" adapters to solve the code caused by his bad cat.I'd imagine 'catalyst efficiency' is the only code a cracked exhaust might suppress. It would have to be cracked between upstream and dowmstream O2's
That was my first instinct. I'm also not certain that the Avalanche needed all of the shitload of work that they charged him for.To break this down to the lowest level, you took your ZJ somewhere ("they fixed the exhaust"), and now you have a CEL and multiple codes. You do the math.
Think you could talk her through disconnecting the negative post of the battery and letting it sit for a while so the capacitors drain? 13mm wrench (or adjustable) to loosen the clamp bolt, flat screwdriver and/or pliers to spread and wiggle the cable off of the post. Let it sit that way for as long as you like, 10m should be plenty. Newer stuff has static mem to keep codes but a '96 should clear once all power is gone.Is there some way to clear the code without removing the battery and with no special tools- as in- something my mom can do?
Absolutely not. Mom is deathly afraid of car batteries, she won't even use jumper cables or the battery charger we have.Think you could talk her through disconnecting the negative post of the battery and letting it sit for a while so the capacitors drain? 13mm wrench (or adjustable) to loosen the clamp bolt, flat screwdriver and/or pliers to spread and wiggle the cable off of the post.

That's fair. I don't know your area, but I know when I was working at the parts store if a mom came in and asked I would have done it for her. Maybe others can come up with better options.Absolutely not. Mom is deathly afraid of car batteries, she won't even use jumper cables or the battery charger we have.
OOC, what is the reasoning behind her battery-phobia? Is it just car batteries or is she scared of changing the batteries in a TV remote too?Absolutely not. Mom is deathly afraid of car batteries, she won't even use jumper cables or the battery charger we have.

I'm wondering if it's connected to her deathly fear of gasoline.OOC, what is the reasoning behind her battery-phobia? Is it just car batteries or is she scared of changing the batteries in a TV remote too?
