Hesitation At Acceleration
Last few months truck has been idling a little rough and then it'll smooth out. But most, not all, but most of the time when I'm accelerating from a stop or even while moving like an on-ramp, the engine sputters. I put new plugs in (took those worthless E-plugs out) and replaced the wires. I was having a problem last year with MAF and IAC so I cleaned them both very well with appropriate cleaner specific for the IAC and MAF. This past early spring I replaced the IAC with a new one. I changed the fuel filter and upon not seeing a lot of improvement I've put through 2 cans of Seafoam over the course of 3 tanks of gas. The truck is never off-road. We do drive it a lot. It's at 180K right now and we've put 24,200 miles on it since September of '09.
I'm thinking possibly one or more injectors not spraying properly due to the mileage. Does anyone concur with this and if so, how difficult is it to replace those?
