I did this and it got rid of the engine light. I didn't have the traction light until I took off one of the ecu fuses out which mad it run loud like over timed and the traction light was on. But when I took all the ecu fuses off discounted the battery and changed out the air filter made sure there wasnt a squirt or something inside haha all went away good luck hope this helps

Same response as @tyrantcf What? Dude use commas and periods properly. I couldn't follow anything you typed at all

Hate to revive an old thread like this. Didn't want to start a new one though.

Has anyone found a solution to this? I'm getting p219a and p119f. Also having quite a bit of misfire at idle. Car doesn't seem to drive and different. Tried cleaning the maf and filter, checked for vacuum and exhaust leaks. Was getting read to start replacing sensors. I have noticed my fuel trims have been pretty erratic, which has got me thinking my o2 is crapping out.

[TruRace]

Just wanted to give an update on this as I haven't really seen any resolutions posted anywhere. I've been getting strange fuel trim readings. Sometimes my ltft will get stuck at 0 for a while or just be all over the place. Haven't found any leaks so I ordered a new set of oxygen sensors and I'll see what happens.

Update
Seems like the replacing the sensor did the trick. Have done a few hundred miles since replacing and no codes.

TruRace, I'm getting the same codes (P119F and P219A). I'm hoping the solution is exactly the same as yours. Dealership just reset my codes and told me to run premium (which I already do). This was the second time. Really hoping it's not my injectors...

Any update on this?

I️ haven’t got the cel in a while but my oft is still reading a lot of misfires at idle across all cylinders (usually 1 and 3). I️ replaced the coils on 1 and 3 but that didn’t seem to do anything. I️ replaced all four plugs. Not sure what else to do. Still drives fine just idles a bit rough sometimes.

log the aFR at idle does it vary widly ?? it should be pretty close to 14.7, might vary a few tenths either way.

I‎t trends under 14.7 usually. Consistently around 14.5-14.7 occasionally dips down to 14.3

I️ was thinking I‎t could be the UEL header I️ have. I’ve read that the heat can cause issues with the ignition coils, but I️ wrapped them with heat tape when I️ replaced them. Didn’t seem to help much.

Check for any intake or exhaust leaks. try carefully cleaning maf sensor with maf sensor cleaner.


AFR going down to 14.3 sounds a little suspect at idle. it should be pretty stable around 14.7 and STFT and LTFT should be pretty stable

[guybo]

My AFR stays around 14.3 too- this is the raw uncorrected AFR, not the Lambda or anything. We have E10 around here and that is stoich around 14.3-14.2

Ethanol itself is stoich at 9:1

The ecu works on petrol afr all the time even if you run e85 ecu will log and work in petrol afr. The 02 sensor reads lamda but ecu converts it to petrol afr and all the tavles are displayed in petrol afr.

So you should see very close to 14.7 idle. Im on e85 and it reads 14.7, the true underlying afr is actually 9 but its displated as petrol afr stoic not ethanol stoic

Open up the oft e85 tunes you see the open loop afr are all in petrol afr even thoigh your running ethanol, it take a while to get your hesd arroind it. You have to inject 30% more fuel to achieve that bogus petrol afr though

[guybo]

I'm going by my AFR gauge. I don't correct it to 14.7

Has anyone found a solution yet. At times I’ll throw codes in groups. (P219A P119F) or (P0171 P0219A P119F P119E). Cleaned injectors and went back to 91 OCT and it threw (P0300 P302 219A P119F). Always pops at idle. Idle constantly fluctuates only when in gear. Slowed Acceleration. Any help would be greatly appreciated.
