Well my service engine light came on a week ago and as soon as it did my car died.It started right back up but the ac didnt work.So when i got home i turned it off and in a few hours sarted it up and it ran fine and the ac worked but the service engine ligt was still on.Around every other day the light goes off and when it comes back on the car will idle real low and die as soon as the light comes on and the ac goes out it just keeps repeating itself.Also my indiglo gauges went out the same time this all happeded accept they wont come back on.Sorry for the long story but here are the codes that came up when i pluged in a neibors datalogger or whatever its called.

P050-heater control malfunction,o2 sensor
P1782-P/ES circuit out of self test range
P1768-winter made input malfunction
P1781-4x4 code( wich i dont even have a 4x4)

So could one of these be causeing the rest of these to pop up?What do you guys think it is that would be causeing the problems i just described with the car dieing only when the service engine light first comes on, ac goes out, idles low and indiglo gauges dont work.

no need to double post :nono and this is not advanced tuning
