SES Light Please Help Today my SES light came on. The only thing I can think off is that, the other day I put 2 gallons off 110 in with 8 gallons off 94 octane. I know its not the o2s because I had them deleted with a custom tune. Should I just burn all the gas out and put new in, then reset the ECM. If I reset the ECM will I loose my Custom program.Could the be something else wrong Idle seems a little rough since the light came on. <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" /> Please help.
Re: SES Light Please Help Defiantly have the car scanned.
Don't sweat it too much. If it popped up after filling up your car, or a few miles down the road after filling, you could have your gas cap ajar.
I just set this SES light this morning after filling up yesterday. My car was stumbling a little on idle as well.

Re: SES Light Please Help The code is P1133. I have the O2s deleted, but could the little bit of leaded 110 burn up an O2. If it is an O2 how do I know which one. <img border="0" alt="[Banging Head]" title="" src="graemlins/gr_banghead.gif" />

Re: SES Light Please Help P1133 HO2S Insufficient Switching Bank 1 Sensor 1
Circuit Description:
The PCM monitors the Heated Oxygen Sensor (HO2S) activity for 100 seconds. During this monitor period the PCM counts the number of times that the HO2S switches form rich to lean and lean to rich. A DTC P1133 sets when the PCM determines that the HO2S did not switch enough times.
Check your email for location diagram.
The info I was reading through also stated that when P1133 and P1153 are both set, it's an indication of fuel contamination.
I guess the O2 sensors didn't like that 110?

Re: SES Light Please Help LEADED 110!! AAGGHH!!! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> that will kill all of your o2's . The lead attaches itself to the porcelin tip of the o2 & degrades its ability to sense exhaust gas oxygen content. I would check all o2's and probably replace them all! Catalytic converters & o2 sensors will not tolerate any leaded gas (even a little).

Re: SES Light Please Help This place has excellent prices -
http://www.parts.com/index.cfm?actio...nt&sfid=213800
They got the left o2 sensor for $73.18, and the right one for $74.59.
The dealer wants like $111 - $114 per sensor.
