I was going to pull the TB and clean and replace the O ring first before I buy the sensors.
My limited runs normally should I get an additive for the fuel which one? I fill up with high-octane gas all the time.
I did a search on the forum and will start with the least expensive fix first then work down the line
any suggestions
The problem is often an exhaust leak. The manual says not to add anything to the fuel. I consider these additives a waste of money. Good fuel with the additives in it is good enough.
Google search the code and see what they say for confirmation of my input and other causes.
