Blinking SES NEED HELP ASAP!
I was driving home and immediately turned the a/c on b/c it was like 95 outside. I get about 2 minutes down the road and the car starts stuttering and delaying in acceleration. I make a right turn and it gets worse and then the SES light starts blinking as well. The hesitation seemed to be just while I was drving
2 minutes later the SES light just stays on with the same delays and hestitations. Without knowing what codes what does everyone with Wisdom on this subject think the problem is?
My mods are in my sig if that helps, I also have a 160 t-stat that is tuned for
PLEASE HELP IF YOU'VE HAD EXPEIENCE WITH BLINKING SES LIGHTS!!!
Also I would get some connector cleaner from the auto store (alcohol base to prevent rusting) and spray the inside of each connector to ensure proper connection.
CHeck all the wire connections under the hood - especially any that were disconnected during any mods.... PCM don't like headers so you may want to buy a program (LS1Edit, HP, etc.) to turn off the tests for O2 sensors, air pumps, etc.....
Was your car flooded? I'm not sure how a 02s could get wet unless the car was deep under water.... I assume that would definately screw up diagnastics and throw a bunch of nasty codes, however....

No, I didn't have to drive through deep water, I did after the SES was blinking for a while but it was just a steady downpour at the time. I guess I'll find out here in a little while and I'll post the results once the dealership calls
thanks man
The O2s don't have to be flooded to act this way. Just the water splashing around is enough to do it.
H/C LS6Z:
I would have the dealership tape the wires and connection to make it more water resistant. My car would shake violently to the point I would turn it off on my own because I thought the engine fell apart internally. The only problem was that it was only running on 4 cylinders (drivers side only) because the Bank 2 Sensor 1 was malfunctioning. It would actually fire on most cylinders (maybe even 8) when I would put it at WOT but at part throttle, it would just shake and wouldn't move for sh**. I'll warn you now that our O2s are $80 each. Can be kinda high if you need 2.
