I have a very random and intermittent miss noticed during consistent highway speed. The miss is very light, but noticeable. e.g. on an hour long trip, it may only occur 2-5 times.
maintanence in the last year or so (which hasn't effected the symptom being discussed).
-New plugs
-New wires
-Used lower mileage coil pack/module
-New FPR
-New fuel filter
-Cleaned EGR
-Random fuel treatment (~3x)
-Sea foam in spark plug holes, let sit for few hours.
-Cleaned TB as good as possible without removing it.
-Cleaned MAF
? Possible culprits ?
-Fuel pump
-injector
-vacuum leak (although it idles fine and shows no sign of this)
Please help!
Thanks for your time
