While first starting out it hesitates, it chugs and misfires under load like when it first goes
in to overdrive at lower r.p.m.s , when asking for power, seems to lessen at times, or
worst with mosture.wondering if coil or ingniter, module?
How long since air filter, fuel filter, plugs, plug wires, ect., ect., ect,. Have been changed?
Fuel pump, wires plugs cap rotor all newer this has been on going for awhile l had a wire short out on me awhile a go it was sometime before I figure it out , I still think it is eletrical or sensor,im still wondering if the coil or module? would it act this way?
Possibly. Is the check engine light on? Have codes read this will give us clues as to what's going on with it. Auto zone will do this for free.
Post the codes back on here.
