this morning while i was driving to school, i got a cel. i was going about 75ish and was messing with my heater when it turned on... or thats when i thought it turned on. didnt have time to check on it till after class, but when i got back and turned on the car, the cel went away? then on my way home (on the highway) cel came back?? i was going to check the cel by jumping the system, but i turned off the car, and when i turned it back on, cel went away again. at first i thought it was something to do with oil pressure or something to do with vtec because of the higher rpm, but i just went out and went through 1-3 gear ending at about 90mph and no cel. i just want to know what it could be, before it comes back again. sorry for the long post

cliffs:

See the first link in the FAQ thread.

 

sweet, i thought that only works when the cel is still on. thanks a lot . car is throwing cel 43 fuel supply system? does that mean fuel pump going bad? or fuel filter getting too dirty?
