In need of opinions to fix problem My car has started acting up "BAD". It sounds and feels like it is misfiring when I'm driving at times "it almost sounds like I'm on a 2 step" the AFR goes from 14.2 to 9.5 when it does this. That is at normal highway speeds not WOT. I checked the codes with my buddies reader and have O2 codes but I don't think they would make it act like this. The codes are It drives fine 75% of the time. I thought it may be my Timing tuner acting up so I unplugged it and plugged in the bypass plug but it still did it but it didn't seem like it did it as long but that could just be me. I also have a aftermarket mass air meter.
The O2 codes are.....
P0131 (O2 Sensor Circuit Low Voltage)
P0134 (O2 Sensor Circuit- No Activity)
P0155 (O2 Sensor Heater Circuit)
Like I said it drives fine most of the time. It messes up on my way to work early in the morning and sometimes when i first leave work. Where should I start Mass Air Meter, TPS, IAC, O2's, if one of these how do I check them? Any ideas??? Thanks
