Engine Code 26 & Engine Noise When Starting, 2 Flashes, Pause, 6 Flashes Options

So I just got this engine code today. What would be first priority to fix? 308,000 miles.

Book says:
Diagnosis - The air/fuel ratio is overly rich

Trouble Area:
Injector Circuit
Injector
Air Flow Meter
Cold Start Injector
ECM


As far as this engine noise, it only happens when it's pretty cold outside like low 30's or below.

i guess itd help if i listed to the noise. LOL just those suggestions since its only when cold

the primary o2 is the one responsible for adjusting the fuel trim, the first one thats in the manifold, before the cat

still getting engine surge? i would look into the map, and tps, and their circuits. use the te2 + e1 combo and drive around and see if the cel pops on, then check codes

-Yea the engine surge isn't overly bad, but it's definitely more noticeable in 3rd going around 25mph I can feel the car bucking more than at any other speed and I could only image what a by standard would say if they saw it happening, lol. I actually replaced the MAP and Igniter, ....could a vacuum leak cause that as well?

So I reset the codes by removing he EFI fuse for a minute, did the TE2 & E1 and drove around for a little like you said, no light came on, but when I do the TE1 & E1 I just get a fast blinking that doesn't stop now.
