How about this... I can feel misfires but my CEL does not come on. That why I think there is something wrong with my ecu, and why I got link error. Or that i am just paranoid and it was their scanner being a tard.

i agree, my as is pretty dumb... but i ask you this. how can i detect a single cycle misfire? what kind of tool do i need?

also, since i erased the codes, the #3 misfire has not come back... so am i now safe? could it just be some mistake or one time thing?

[ashah000]

It could have just misfired once for some random reason, and the ecu stored the code. But if it doesn't come back your good

Waht did you do to stop the misfireing? I have a misfire in cylinder number 2, and its pretty bad, So if anyone can help me out, becuase i took out the spark plug and it was crispy black at the bottom, so i donno what shout i look for to fix this problem. If any help you cam email me at [email protected]

i never had a misfire in my cylinder... it think it was a bad code. i reset the IAC motor, and all the codes went away and never came back.

I had to actually start the car in order to get the scan completed, otherwise yeah you get a error
