Default ses light

my ses light comes on beacuse the air pump on my car is no longer there when this comes on does it pull timeing out of the car and add more fuel like its in a limp mood kinda deal beacuse when the light is off the car runs great but when it comes on it runs like crap and sitting at a light and then takeing off it acts like it loads up but only when the ses light is on it does that. when it is off it runs great. so do i need to get this tuned out of the pcm or can i just stick a 30 amp fuse in the air pump slot in the fuse box and call it a fix until i get it tuned ?

The absence of the AIR pump will not cause any abnormal running conditions. I would have the PCM scanned for any additional codes and go from there.

Also, as long as there is a good fuse in the system the SES should stay off. Start with that first and see if it helps.

the pcm has been scanned and the only code that shows up is the air pump code but like i said when the light is off the car runs great but when it comes on the idel gets rough and it hestates somtimes when leaving a red light but once on the road and just crusing down the hwy runs fine
