Oxnard,
California
On my way home from work, I started having bad random missfires and sometimes even backfires with CEL's, the CEL's came and left as i got missfires, it mostly occurred while going into first gear or changing gears. This all started after installing ECMLINK V3...the previous owner was running speed density probably this has something to do with it?
Anyways it got to the point where i had to drive into a local neighborhood and stop, when i did the motor turned off completely and got a CEL. It turned back on right away but at idle it started missfiring again, I was about 5 miles from home so i just drove home like that. Probably about 20-30 minutes after i got home, i pulled the laptop and captured a cruise log around my block to see if i was able to capture what was going on and maybe have someone check it out. Unfortunately, the car drove fine and even did 2 small pulls and nothing, nothing out of the ordinary.
I have attached the cruise log to see if anybody can pin point my culprit or see if something is awfully wrong. I havent installed my wideband due to no time so im going off the AFR estimator.
Thanks.
