|Just hopped in to make a quick run to the corner store (beer run) and immediately noticed rough running. Like missing a cylinder.
Gonna go through the normal "coil pulls until you find the one that doesn't change idle" but I'm a little perplexed as to how it could go from running great to missing in the space of an hour w/o touching anything... ? Only difference being the motor being totally warmed up.
Background: Changed injectors, injector connectors, coil connectors, whole top-of-motor fuel system, PCVs, plugs re-gapped to .035 (they all looked uniform and perfect) plenum TB bypass, and ECU.
Note: I also feel like I heard a bit more noise from the fuel pump than usual. Might be a totally different issue, as I think I had noticed that once or twice before.
Former Stage V addict... off the wagon.
