Hey guys, as a lot of you know I have been chasing down a random stall out issue for the last 2 years or so on the truck and it has gotten progressively worse as time has gone on. See that thread here. I have tested everything I can to no avail and checked what I can with the data logging on the tech II still with no hard evidence of anything, well... crapping out. It still only stalls in the summer when it is hot out but it used to only be once or twice a year in the beginning. It then went to once a month then to almost a daily occurrence at some points and I couldn't catch it. Whenever I had the tool logging it behaved. Even when I could duplicate the issue 3 times in a row when plugging in the tech 2 it would behave. It was at the point where I could start the truck walk in a backyard and come back out to it not running. It would just die idling. The easiest way to get it to do it is a decently hard acceleration on a hot day to around 55 followed by a coast to a stoplight and then sitting there at an idle for a few minutes. That is the most consistent duplication I can create. And it always happens as the light turns green lol. I am restating a lot of what is in that other thread but some new issues have arisen.
Now on the highway I am starting to get a random flash of the CEL, usually coasting onto an on (or off) ramp and just bliping the throttle (idle to maybe 1000 rpms). I am going to go on a limb and say it is related but no one wants to do a ride along so I can data log unless it's their vehicle. It's kind of hard to run the tech II and drive at the same time on the highway... Well okay, I just don't want a ticket or anything, I can do it but it makes me uncomfortable if you get what I mean. When the cel comes on, or well flashes, you feel the truck lose power for like a split second, almost like the motor is killed for a second, everything goes stalled mode for a flash of a light. I think it's getting worse as today it happened a few times in town and I am just worried it's going to start dying on me on the highway. If anyone has some tests I can look into that are easy to run myself, they would be greatly appreciated. Thanks in advance.
