Help!!! Dtc codes p0174 and p2197

[Kochieey]

Got headers x pipe flowmasters outlaw mufflers cold air intake and custom bama tuner installed on my 2007 mustang gt automatic about 2 months ago and now my check engine light is on and I'm getting the codes p0174 and p2197 they checked the o2 sensors those were fine.. Next they are doing a smoke test to see If there is any vacuum leaks.. Any other suggestions ??

You could have a bad sensor.

[Kochieey]

Nope car is at shop they checked and tested o2 sensors they were all good... Next they are performing a smoke test to see if I have a vacuum leak

[WillysYJ]

codes p0174 is linked to your MAF sensor. have you tries cleaning that?

[Kochieey]

No I didn't try cleaning it.. How do u clean it ? Sorry I'm new to this... You use a maf sensor cleaner right that they sell in the auto store

[WillysYJ]

You can get a can of MAF cleaner from the auto parts store, DO NOT USE CARB CLEANER! Pull off the neg battery cable, pull out the sensor, spray it a couple times and let it sit and dry out(shouldn't take long at all) reinstall and reconnect the battery and try it out. Definitely keep us up to date. Btw, I would spend the few $ on cleaning the sensor before getting a smoke test done.

I had the same problem a few months ago i cleaned my MAF sensor but everything worked fine turns out i cracked my cold air intake.. I had a JlT carbon fiber intake now i have a C&l racer intake. I recommend taking off your intake and inspecting it... Take it completely apart

Ohh by the way you crack your cold air intake by over tightening it... Lol carbon fiber is very fragile

Lean faults on bank 2. Monitor fuel trims for both banks at idle and 2500rpms. Swap O2s from bank to bank and retest. Intake manifold off recently?

Carbon Fiber is not fragile at all! It's prolly was the gel coat or the fiber glass that cracked, most of the CF intakes and auto body parts are mostly fiberglass with a few layers if carbon fiber, i just know by working with it for 10 years lol

Okay thank you I will check it out

I had p0174. My intake was loose. The cars RPMS jumped when idle too.

Okay keeping every body up to date friday i gor the car out of the shop they told me they unplugged and tested the o2 sensors and said they were all working and then the cleared the check engine codes and called me to pick up the car and see if the light came back on ... Well i drove the car for about 100 miles this weekend and filled up with a full tank of gas.. And no check engine light came back on I'm keeping my fingers crossed hoping it stays that way!

[galindojr24]

How do you fill the way your car drives? Normal? Hows your idle?

[Kochieey]

Yes I been driving the car and everything feels normal drove over 100 miles and the check engine light never returned
