!EGR=blinking SES light? Hey... My SES light has been blinking lately.
No loss in power, or anything funky.
Went and had it scanned and only 2 EGR codes came up...
Are they causes my SES light to blink?

it wont. a blinking SES light is a "catalyst-damaging" misfire and doesnt set any codes.
i know when EGR is actuated the fuel trim does change to compensate for the burnt exhaust gas but i would assume the PCM sees the EGR circuit malfunction and wont change the fuel trim in your case. well maybe it is and thats whats causing an occational misfire.

how bout a blinking ses light with no code thrown?????? is it phantom, anything to worry about. i keep my footo ut of it until it stops blinking. its only happened a few times when i hover a gear around 3-4k
Um Yea a fuel pump can become weak!! I know it happened to my 98 z28, I own a shop here in tn and get alot of cars in with weak pumps. Pumps do go weak. As for the it being lean didnt I say Fuel filter? Hope you figure it out man.
