The truck is in my sig, now its hard to explain this because it only does it seems like when it wants to pi$$ me off , but any how it usually does this when I am pulling a hill or leaning into it semi hard, like pulling a hill or accelerating with a load it skips and hops some times not so bad but others its so unbearable I just wanna park the **** thing, now this has happened before and I was told to clean my map sensor and I did and it fixed it so when this started back up again I went to the map sensor right away and cleaned it and this time it did not fix the problem. Example, today for instance I was pulling a grade about 6% give or take and about 70 mph and if i remember correctly about between 15 and 20 psi of boost when it started doing it i mashed the skinny pedal and it seemed to have work its self out, now this does NOT do this all the time under the same conditions just every once in awhile. Can anyone explain this or has had similar problems?
Your help is much appreciated!!
Thanks again and Semper FI
