P1123 code with freeze frame data, help needed
I got this pesky code that won't quit going away and it's the P1123. I ran the OB2 kanobi on it the first time I got the code and then today when I got the code again after clearing the code. I don't know what they mean, but some are obvious to know. Here are the flash freeze data that OB2 Kanobi gave me:
the 1st P1123 code today's number with the code
Fuel Sys 1 CL
Fyel Sys 2 NA
Calc Load % 4.7 5.0
ECT (degF) 174 167
STFT B1% -11.7 -21.0
LTFT B1% -10.1 -7.0
Eng RPM 880 840
Veh speed (MPH) 16 3
It's saying something is up with the Long Term fuel trim being too rich and I'm wondering what can fix it. This is the only code popping up.
I have replaced my MAF, O2 sensor, Throttle position sensor, shot throttle body cleaner in the throttle body, purge valve, charcoal canister, and filler neck. I am leaning towards fuel pressure regulator, but I wouldn't know how to test that. Any idea would be great.

Did you replace the MAF with a Hyundai MAF or aftermarket? If it was aftermarket, I'd get a Hyundai MAF. Otherwise, check the fuel pressure and check for leaking fuel injectors and/or fuel pressure regulator.
