Intermittent Stuttering

[GIZMO]

I was wondering if you guys had any suggestions as to what could be causing an intermittent stuttering with the car. When it happens, the car stutters and lurches (very uneaven acceleration almost as if a spark plug wire was in the wrong spot) like mad. Last time this happened I threw a cell 41, I believe. We cleared up that cell and the car ran great. Then it came back the other day. I was thinking about trying a different set of injectors and checking the wires to see if there are any cracks and maybe even the transistor. Do you guys have any suggestions?

Have you done a boost leak test? Replace your spark plugs.

replace your plugs, check wires and everything that could be loose. i had the same problem a couple weeks ago. Changed out my spark plugs and it has gone away since.

test the coilpack too

The shop that built my engine said they put in all new plugs but I suppose I could check anyway. How do you test the coil pack?
