OK guys..my Check Engine Light popped up on my stock tC 2 days ago..I got the code read at Autozone and it turns out i have P0031 Low Voltage on the Bank 1 Sensor 1, and P0303 Cylinder 3 misfire.
I called the dealership today and they said the next available appointment they had was a week from Monday so I'm kinda screwed..

My question is..does anyone think I should just change the plugs and wait for my appointment..or just wait for the dealership to check it out???

Plmk

just wait. don't touch anything.

 

i would wait or try to find another dealer that can look at it quicker. i know my at my dealer i can just drive up w/o apointments.

 

dont touch
let the dealer do the job

 

to late..the job is done and the cars seems fine..i have a job that requires reliable transportation, and i CAN NOT screw it up...you guys think the dealers is going to be ____ed??

 

Did you pay to have it fixed? Are you not under warranty anymore? If you paid to have it fixed, then why would you spend money on something when you could have it done for free under warranty at the vendor?

 

What did you do?
Explain to the dealer that you needed you car and had to do something...
It's not like you put a turbo on it...or did you?

 

^^^ no kidding, alot of dealers are crap, they should be looking at your car that day or hire more mechanics, since they obviously cant cover all the cars they sell, and complete the warrenty work that they are selling with the car. I can see miner problems being pushed but something like a misfire...lol, i bought the car for everyday transportation, if i have to wait to make it work right...whats the point of buying one.

 

all i did was change the plugs..the misfire code is gone, but i still have low voltage bank1 sensor 1 P0031

 

All good - they can't give you crap for that.
Take it in when you can - don't do anything more.

any more info on the p0031 i have the same code, wtf does it mean anyways?? i dont get it

 

I think it means the frony o2 sensor is bad. I would take it to a dealer and have then deal with it. Hopefully you will get a new sensor out of the deal.

 

sounds like you also need a o2 sensor. if your still under warranty don't worry about it, you can still drive around until your appointment day. as for the misfire, what plugs do you have and how many miles on them?

 

so p0031 means that the 02 sensor is bad??

wow!..i cant believe this post is still active..well it turned out to be a cloged injector due to winterized gasoline..140.00$ later and the problem is fixed..once the injector was cleaned, all codes went away..ive had smooth sailing since..good luck to all
