I've got a problem...
Originally getting codes:
P1124 Manufacturer Controlled Fuel And Air Metering
P1126 Manufacturer Controlled Fuel And Air Metering
Other symptoms: unsteady idle, Stalling suddenly when HOT (like after several autocross runs) but starts right back up. Otherwise running really well. No drop in gas milage. No driveability issues
Checked ICV- seems good. I had already bought an AOS and gas filter so went ahead and replaced them with no change. Checked for air leaks by using engine starter spray to see if get reving- nothing. Fuel pressure at 49PSI at idle & steady
Now getting above codes with 2 additional codes and still same symptoms:
P0130 Oxygen Sensor Circuit Bank 1 Sensor 1
P0150 Oxygen Sensor Circuit Bank 2 Sensor 1
Any thoughts? Could the O2 sensors be going bad (All 4 have been in the car for 170,000 miles)

You did not entirely remove the cap from the list of suspects... MarcW - Wednesday, 16 May, 2012, at 4:23:07 pm |

Should have mentioned I checked oil fill cap by taking it off car ran crummy- put it back on ran fine.
The P0150 is same as P0130 except for Bank 2- I am leaning toward O2 sensors are on their way out/close to dead.
Only thing I hesitate on is the idle hunting, can an O2 sensor cause this? Could bad/dieing O2 sensors cause the P1124 &1126 codes? (Seems likely to me as O2 feedback will effect rich/lean mixtures)

Up to you if you want to replace the sensors. But with 170K miles on the original ones... MarcW - Wednesday, 16 May, 2012, at 10:43:54 pm |

I checked the oil cap as you suggested- no real help. I think at this point given 170K miles on the O2 sensors I am going to replace all of them even if they are not the cause of my issues (although I strongly suspect they are).
I will post back after I change them and let you know if they fix. Will pick up new oil cap also even thouigh does not seem to be issue as it is also the original oil cap. I still have a lot of original stuff on the car...
Thanks for the help and I will let you know how it turns out with the O2 sensors.

Not trying to pile it on but I believe if you go the remove the exhaust manifold route... MarcW - Friday, 18 May, 2012, at 6:52:00 pm |
