I've notice my truck will act like its runnin on 6-7 cyl. when it hits the last shift, possibly when the converter locks up. Heres the deal though its not all the time, there is a slight hill leaving a red light about 2 miles from the house it does it in the same spot as im topin that little hill and i havent noticed it do it anywhere else. After bout half mile it seems fine the rest of the time driving. just got me wondering if its a coil pack. any ideas? been a off and on problem for a while and sunday it was really bad jerky it was missin so bad. I laid the pedal to the floor and it just didnt want to go cuz all the missin goin on.
i havent even looked, i had soo much bs goin on since it did it so bad yesterday i havent thought much bout it til now. But i was thinkin you told my you had just put new ones on it and changed the plugs.
Ill see if any codes show up with the edge tomorrow. I bet theres no way to check for a bad coil pack when they workin right.
