I had my cel checked at the auto store and this is what was told to me Post Catalyst Fuel Trim System Too Lean Bank 2
He suggested I get a diagnostic on my car any thoughts on this.
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
