Well getting off the highway tonight I jumped on it hard and here is the first problem. When I get on it I get like a bad pulsing like it fuels hard and then gets none. That or like it builds boost and then the wastegate opens and lets off all the boost?? I dont think its the turbo though because when it does it the is no smoke between the shudder. Also when I got to the light at the off ramp the truck was running like crap. Missing and shaking real bad at the light stopped. I put it in neutral and gave it a little fuel and it went away after like 4 or 5 seconds. What could this be. I am leaning to the VP with one foot in the grave and on on a banana peal. What do you guys think, thanks in advance.

 

any codes? apps?(i'd bet on this, may not throw a code right away)... crank sensor?

 

No CEL or codes. How would I determine the apps or rule it out
