runs like crap need help my car has been running like crap for over a month and i havent driven it since then well today i ran codes and found the po300 and po400 egr.
po131 o2 sensor b1 s1 low volts
po134 o2 sensor b1 s1 no activity
i erased the codes and started the vehicle it ran fine at idle then the real test was driving at probably 30% throttle i can hear it missing and sputtering a bit. it is also real rich smelling throught the exhaust. i then went and floored it which in turn took off like dogcrap and then sputtered a bit and just felt sluggish then went rapidly. as i slowed to a stop sign it was back to running like crap still. so i believe it can be the cap/rotor it has 140k but has been changed but that dont mean its good. i even brake tqd a bit and it misses bad so i know its missing bad. what do all of you think bout my codes and bad miss.

lift your car and diconect your o2s then see how it runs. then you could go from there. my buddies 95 formula was doing the same thing we replaced the opti and nothing it turned out it was only the o2s.
If your car has 140K and the opti and o2's are both original, they are both probably due for a change. When my opti went bad, I has a p0336, p0300, backfiring, and stumbling.
P.S. If you need a new opti, get an AC Delco.
