STABILTRAK AND AFM MISSFIRE


Recommended Posts

I have a 2015 Silverado Ltz 4x4 afm oil lifter manifold is causing #7 to miss if I tune out afm and turn it off will that solve it? Biggest issue is stabiltrak I attached a video gauges jump up and down lights will flash temperature on radio unit goes to a low temp or no temp at all none of my digital gauges work this goes off and on all day any takers? I looked up and looked around at everything possible it also will kill my power steering sometimes and shifts very hard or won’t shift at all. Wheel speed sensor maybe?

If the AFM system is causing cylinder 7 misfire then just tuning it out is likely not going to fix anything. There is a actual problem with that cylinder, usually a lifter problem.

 

The whole electrical freak out problem, that is tough to say without digging into it. Could be wiring, bad grounds, dirty connections somewhere.
