’03 3.3L XE- Gentle Idle Hiccup
At idle, there is a barely noticeable
bump/shudder/hiccup. The frequency between the bumps is
random. The intensity is stronger when in drive than in
neutral, and it doesn't always do it. I'm not sure how
else to describe it.
My check engine light is not on, and there are no pending
codes. The truck runs fine when not at idle, no
noticeable loss of power, but I think I might be getting
slightly worse gas mileage than normal.
It seems like an ignition problem to me, but the plugs
and wires are new. Not sure what else to suspect. Coil
Any ideas would be appreciated.
