Hopefully someone has seen this before.
When the truck warms up to 140F the MAF drops to 5.12 and the turbo vanes close to the limit on the tables. The IAT takes a 60F jump.
The truck bucks and bursts during this time.
At 144F everything returns to normal. The problem ONLY exists in this range. I got a p102 MAF code once, but it has not returned. I removed and cleaned the MAF.
It seems to me that if it is a bad MAF, it would have problems continously.
Attached is a couple of logs of the event. Any input is helpful. This one's got me stumped.
Thanks,
Matt
