Surging, buck, & jerk
Ok I have read and searched as much I can so I figured I would start a post. This summer I have add a good amount of work done on the truck but something is still not right. This is what was done
Studs, Egr delete, 8 new injectors, Air dog II, Innovative stage 1 fuel lines, oil bypass, coolant bypass
So I got the the truck back from all this work it was hard starting and it bucked and jerked REALLY bad until it got completely warm. I took it back to the shop and got all sorts of injector codes. So replaced the FICM. Now it starts and idles butter smooth, even when its cold (25 degrees).
But when I drive it, it takes off just perfect with no hesitation but around 1500 rpm and above it gets this funny hesitation and its like I have a dead pedal. I can ease it up to speed but as soon as it gets into overdrive it has a pretty bad buck and jerk. There is a distinctive miss in the motor, it gets better when it warms up but does not disappear unless its been driven for 30+ minutes.
Any suggestions??? It seems odd to me it starts and idles so smooth, but still has this hesitation, and bucks and jerks in OD.
