My truck is basically all stock except I have the deck plate mod and a K&N drop in filter. When my truck is warmed up, I stop at a light, and the engine reaches it's lowest idle speed, there is a weird feeling. My dad called it a miss. the engine will just kind of shake and the rpm needle will move ever so slightly. I don't really know how else to explain it. It happens randomly and I don't really know what causes it to happen more or less. It might happen 2 or 3 times when I'm stopped at a light. The truck runs perfectly normal at speeds. I guess it seems underpowered going up a steep hill but I always figured that was normal for the small truck (kind of bogs down). Anyone have any thoughts? seems like it could be just about anything. Milage is typical ~17MPG.
2001 V6 double cab
Plugs are fairly new, 30k miles maybe
drained gas and put in higher octane gas
Cleaned Filter (still need to clean MAF, but I did at last interval)
