Soooooo quick backgrounder: ‘05 Roadster Limited, 41K miles. Previous owner put on the most recent 4K miles in the last 2+ years, so lots of sitting. Bought it, drove cross country 4K miles in 3+ days with zero problems. Depending on what was geographically available, I only put in 92 or 93 octane. Probably the most fun car I’ve ever had!
Back home, after it rested overnight, drove to DMV & home, about 20 miles, mostly 60-65 mph in posted 60. Runs Perfectly!! BUT, Check Engine light came on in last 10 minutes of that ride. Bought the Autel MS309 and it says: “P0175, system too rich bank 2”.
NO clue what that actually means or what I should do next! Ideas? Answers?
Thanks for your help!!

 

Re: P0172 & P0175"I cleaned my mass air flow sensor and throttle body today. It runs like new again."

 

OK - Thanks! I’ll do that.

 

When you clean the TB and MAF, use the right spray designed for the part your cleaning and follow the instructions on the cans. Also, don't start the car until all the spray had dissipated off the TB & MAF. Good luck!

Thanks! Good to know! I will follow your advice. I ordered CRC MAF & TB spray cleaners from Amazon.
