Error Codes

Hi All

Fulltime "lurker" / sometime poster...

My '98 with 121k mi is throwing a consistent CEL and 4 Faults Found:

17544 - Fuel Trim: Bank 1 (Add): System too Lean

P1136 - 35-00 - -

17546 - Fuel Trim: Bank 2 (Add): System too Lean

P1138 - 35-00 - -

16684 - Random/Multiple Cylinder Misfire Detected

P0300 - 35-10 - - - Intermittent

16690 - Cylinder 6 Misfire Detected

P0306 - 35-10 - - - Intermittent

If I reset the CEL, it comes back in about 50mi... Also, she occasionally idles rough when hot, put in a double dose of Techron to clean injectors, also accompanied by rough idle..... Any Suggestions? I am thinking it's an O2 sensor...

BTW I have an "uncured" hunting issue that I live with; & I'm about to do front a suspension rebuild and tranny output seal.

Mods: ECS two piece brakes, tranny coding, 17mm spacers, XM radio.

Thanks for your input, guys!

log o2 -should be -12 to +12 with warm engine

suggest it could be but seems funny that both banks gom at once= will show up there as code only sets when outside parameters
check for air intake leaks and clean filter etc
DO NOT use silicone near this area as it will kill sensors
