^ I needed to know that. Cool. I didn't want to take that risk which is why I was asking about manual EVR actuation.
1st off the intake will get pulled off and thoroughly cleaned. If by chance that doesn't fix it then I'll verify the solenoid actuation to try to rule it out. If the solenoid is good, then I will have to check the grounding of the EVR during a driving cycle. I'll let this one rest for now until I can get the truck. I'll be owe'n you some lunch dinner and a 12 pack after this.
Thanks Jody. I'll be letting you know.
