Last week I pulled codes 1133 and 1354. I replaced the a/f sensor (front side) and eliminated 1133. To tackle 1354, I checked out the OCV and cleaned the OCV filter. I cleared the codes and took the car for a test drive. Was 10 minutes in when the CEL came on again, had random misfiring causing a studdering in acceleration, and the brakes got stiff.
Ran another diagnostic check. Now I have gone from just a 1354 to reading: 0300, 0302, 0304, 0306, and 1354.
I should also mention that the coils are in working order. Therefore, I think I can eliminate the codes 0302, 0304, 0306 as being related to something else. Where do I look next?
Suggestions are fully encouraged, and diagrams/pics are welcomed. Thanks!
