    Default Engine miss on Chevy 6.0 V8

    My 2006 6.0 v8 Chevy express has engine miss noticeable at idle and acceleration. My mechanic has identified #1 and #4 as the problem. Mechanic has replaced injectors, replaced intake gasket, swapped coils from known good cylinders to bad cylinders and did a compression test on all cylinders showing above 170 on all. The engine continues to miss on #1 and #4.

    The miss is always there 99% of the time, more pronounced at times....Rarely the miss will go away or at least not be noticeable to me for a few miles and then go right back to a continuous miss.

    Can anyone help me with this mystery

    Tell your mech to check grounds on ecm ..injectors may have a bad corroded ground.
    Ask him to look up service bulletin ..on this.
    Try cleaning the maf sensor.
