Thats because codes are there to AIM you in the right direction, not tell you exactly whats wrong. Its just a step to make ur diagnosis easier.

 

o2 sensors are misdiagnosed, it seems to be the "common" problem to fix but it really doesnt fix anything. That one o2 sensor is linked with the injectors which will mess up everything just from running too rich or lean. I would highly doubt the o2 sensor as anything to do with it since an o2 sensor wont cause a loss of power.

I would take the car in to the station to show them what its like now, and that you bought their fuel before you go and fix the problem, so you have more leverage if it is actually the gas.

Like everyone else says get the code read, you can't be angry at the station if you don't even know what the problem is.

 

especially if it's an evap code because you forgot to tighten your gas cap 4 clicks.

 

Sooooo.... Anyways, the code read cylinder 4 misfire, changed the plugs AND wires, (Changed the plugs only and still had some hesitation, but not as bad. And TRUST ME, those plugs were gone!!) and, OH HELL YEAH!!! She's back and more aggressive then when I bought her on Feb 21st of this year.

I am thoroughly impressed, even more so than before.

And before I forget, Thank you all who gave their advice, I appreciate it!

Nice to be a part of a close knit community that helps out when one has difficulties.


But I'm still never buying gas from that place again!!!!

 

pretty sure everyone is glad they could help...

so the lesson here people is "If you have a CEL, get it read before jumping to conclusions"

 

Yea I had the same exact problem a few days ago also, just replaced the plugs and wires and it fixed it.

 

I carry a spare spark plug wire and spark plug now...it takes what 30 seconds on the side of the road? Dont ever want to have a repeat of that happening.

 

Each spark plug wire has a different resistance.
These are the service standards:
wire1 15.3kOHM wire2 12.4kOHM wire3 10.7kOHM wire4 8.8kOHM
replacing any old plug wire with a spare is not a good idea and may cause problems. 1+4 and 2+3 are on the same circuit and different amounts of resistance will change the operation of the plug. Carrying a spare wire is only good if you accidentally cut a spark wire in half, otherwise drive to the auto parts store and pick up another set.

 

Thanks for the info DTN i did not know that.

 

AND . . THERE's another lesson for you here - - YOU CAN'T AFFORD A LAWSUIT if

you're buying cheap gas
