The 93h ran great for about 6 months then all if a sudden this code pops up. I cleared it after researching and within 30 miles it went up again.
Had to go to the dealer and flashed backed to stock and left it stock since I have to go back again for them to fix the dumb electric start that came with the car.
It has came on 2x in 300 miles on the stock tune so not as frequent which makes me think or is the AFR or possibly a small exhaust leak ?
Ryan at bama thinks the code could mean an exhaust leak but all the threads online had the afr as the cause and one case had bad o2 sensors. I will datalog after I go back to the tune after im done with the dealer. I then want to see if it pops up on the different tunes. If it doesn't then maybe it was just running lean on the stock and maybe something funky in the old tune?
There no loss if power or anything. I checked and found nothing loose underneath and I would hate to have to pay $100 to check for an exhaust leak and that doesn't include fixing the leak of one is found.
Anyone else have this code pop up!
Thoughts and suggestions?
In our experience with this code we've usually seen something related to the exhaust. A small exhaust leak, bad o2 sensor etc.. I wish I could be more help to you!
I recommend just keeping in touch with Ryan at Bama and we will help you troubleshoot with whatever issues you're having!
