Ok, so i have had a low voltage code on the left side for quite some time, car ran fine, only suffered some mild mileage loss no big deal. however, recently it started running REALLY crappy, alot like people describe in their P0300 code posts, i do have that one also, anyway i decided to run a scan on her and i pulled 10 codes, my problem is the troubleshooting process that i want to go at since i didn't just pop the O2 codes, i also popped one random missfire (P00300) also a Knock sensor Low Input code (P0332) and an a/f code (P1133) the way i'm looking at it, the O2 sensors ALL being bad could cause the miss, as well as the bad a/f, correct me if i'm wrong. however, that knock, that's the one that bothers me, i have read about poly trans mounts causing problems with knock sensors, and i just recently put solid motor mounts, and a poly trans mount in the car. however, there really doesn't seem to be a way to prove, or disprove the Knock sensor aside from HP tuners, or some other scan program which i do not have, nor have access too.

anyway, i know this is getting long winded, but my plan of attack is to change all 4 O2 sensors, reset codes, drive it on the road/hway mix for about 50 miles (i have a route i like to drive) if no codes pop call it good? also, i intend to do plugs, wires, fuel filter (they are all due as well)

anyway, list of codes if you didn't get it are
P0131, P0135, P0138, P0141, P0155, P0160, P0161, (O2 codes)
P0300 (Missfire)
P0332 (Knock sensor)
P1133 (air/fuel)--could be MAF, however, with ALL O2 sensors DEAD i can assume that that could cause some type of bad AF reading.

anyway, experience, and assistance is welcomed, requested, and appreciated!!!

 

Ok no help so far, I'll keep it simple, Bosch, or delco, and where from? Auto zone has the Bosch for about 67 a piece.

 

Oh, and in that, auto zone gives them all the same part #, however, specifies all 4 different locations what gives??

 

Pull the plugs also. Might wanna see if any are scorched or if theres carbon deposits "caked" on them and if they are, from which cylinder. Get some new wires in while your at it. ...

 

well, i'm going to check the plugs when i change em out. they are about due, also, wires are due, so i'm going to do that as well, but i will definentally make note as to where the problem "plugs" are. but since i'm popping the low voltage on all my O2 sensors, they gotta go. it's going to be an all at once thing. kinda hard to track issues that way, but again, alot of the items are ready to be replaced anyway!

also, any word on O2 sensors? i'm getting tons of mixed messages reading through the forums as to which to use, weather or not they have diff or same part #s i mean, what gives lol, lets get some consistancy!!
