Dual cat 99 Cali 4Runner
Dual cat 99 Cali 4Runner
Hello,
I am now in Colorado and have a California version with 2 cats on it. I am throwing an engine code that says I have a bad cat but not which one. They cost $750 and $950 each.
My question is:
Can I just run the rear cat and replace the front one with pipe?
Or will this throw the computer into a brain freeze?

Just posted on this subject in the other thread you wrote in...here is what I said...
Hey Yukute, I have a Cali 4runner in Colorado too. Was getting codes after having it for a year or so (140-150k miles) and looked into this. Found out that Colorado is really astute with their testing so decided to keep it stock. Found the correct front sensor (A/F sensor) online for $80 bucks. Cleared all the codes for about three months, then started up again...started to run 91 octane and did a couple good fuel cleaners and have been great ever since.....IMHO its hard to get past keeping the exhaust stock here unless you want to spend the $$$$. Good luck
