I have a 2006 Cobalt LT coupe 2.2 at 130K miles. Ran great since I bought it around 124K miles.
A little background of what I've done since what I'm going to explain started:
Replaced both up and downstream O2 sensors as they were bad, and changed out the exhaust (catback) since it was heavily corroded it out.
Drove the car for 2 days no issues, until I was meeting a friend for lunch got to a red light and the NO traction control light came on. Didn't care much about it yet until I started driving and EVERY single gear was a really hard shift like jolting me forward. I met my friend which was just 2 miles down the road and when I finally had left, saw the CEL light was on.
I have an OBDII reader and here are the codes I'm pulling:
P0030 heater control circuit 1 bank 1 sensor 1
P0036 as above bank 1 sensor 2
P0102 MAF circuit low
P0135 02 sensor heater circuit bank 1 sensor 1
P0141 as above bank 1 sensor 2
P0443 evap emission system purge control valve circuit
My questions mainly are: 1. What caused brand new 02 sensors to go bad again so soon? 2. Would ANY of these issues cause the transmission to be jerking like it is? 3. Is there anything else I should check since these are vital systems that could have caused any other problems (best to address now then later)?
I've had several home mechanics from which one is certified and used to work for Ford (yeah its Ford but whatever) and he recommended the fluid being changed in the tranny. I have had others say it could be the wheel speed sensor, but why does it not show up as a code?
Since that day, the car has sat parked, I start it up from time to time, but I have someone coming this weekend to help me fix it up; before I buy any parts what is everyone's best advice?
No rude comments, or misleading information please. I'm turning to people on this forum who know more than me for help. Please send me in the right direction. Thanks!
