NEED HELP. running rich

[airickmatthews]

I’m broken down at Orlando international airport. Car threw a code of p172 on ktuner. Looked it up and says I’m running rich. The car bogs hard in first and second and doesn’t wanna go anywhere. Mods are downpipe frontpipe prl intercooler short ram. Just flashed back to stock and all the warning lights on my dash turned off. Hesitant to drive it and see what happens. Any insight?

Nope. Injen short ram. Been running this tune for months with no issues. Flashed back to stock and seems ok? But haven’t left the airport yet, just drove around the parking lot.

What parameters should the stft and ltft be at? I drove home on the stock tune and everything ran smooth with no issues.

What exact tune were you running?

Injen has had issues with fuel trims on their intake. What was the LTFT number?

Flashed back to stock and the ltft is ranging from 0 to 2. So that seems alright.

It can take some time of driving for the LTFT and STFT to get so far off they throw a code. I bet your trims were bad over that month of driving and it finally got so far off it coded. Injen is known to throw them off pretty bad. Do a datalog next time you are driving, do some cruising and then a WOT from 0-60ish. you can graph it and see how bad it is

Sounds like you need to throw that intake in the trash.

Lol I don’t disagree with you on that one. I have the prl cobra Race MAF one in my closet, just waiting on ktuner to release a basemap for it
