my car started running rough on the way to work this morning. it had very little power and sounded like it was running on only 2 cyl. i pulled the plugs and they were white in color. put new ones in and it runs good again. looks like it was running lean. what would cause this. the plugs i pulled out were not that old.

NGK plugs. as far as the fuel goes i did notice the local station has a sticker on the pump that says contains ethenol but i've been running that fuel in my other 90 legacy with no problems.

all pump gas contains at the least a bit of ethanol..... and what about the injectors?

 

what about them? it runs fine otherwise.

i was wondering if one of the sensors acting up could cause this.
