Morning !!

I have noticed some hesitation & stumbling @ steady speeds - around 45MPH or so - & decided a tune up was in order. Cap, rotor, wires, plugs , air filter, & fuel filter have been changed. The plugs, wires, cap, & rotor where a no brainer as they were pretty well worn - the fuel & air filters were "iffy" , but I changed 'em anyway.

The mileage has gone up, so I know I am doing something right , but the stumble is still there.

Coil ? Fuel pump ?

Any help is appreciated !!

Oh, the car is a F.I. '90 Nissan Sentra w/ a 3 speed auto tranny - I posted here 'cuz some of the 3rd Gens had 4 cylinders in them.


Thanks !!!!

Britt
