why does my engine sputter

[scoobs]

I have a 258 6cyl 3 spd...has been sputtering through the gears. Replaced the plugs, plug wires, and distributor cap. Still sputters. Any suggestions?

Are you getting enough fuel? Too much fuel? Do you smell gas? Timing off? Tell us some more.

I suggest that you pick up and hook up a vacuum gauge. Reference to this link will most likely help in diagnosing your issue.

Bobcat:
Hummm...timing sounds like a winner...not sure about a vacuum guage as was also suggested.....don't smell gas...however, the little spongy filter in the air filter was soaked with gas....what could that mean?

 

[bobcat481]

Means your flooding out some how. Does it back-fire any? I don't know the 258's well, is there any vac or return lines near the filter that the fuel could be getting in from? Have you messed with the distributor any other than changing the rotor? Is there much play in the rotor (meaning worn dist. gear causing a timing issue)?

Will check these items out...thanks!

Id look at the fuel pressure..

#1 fuel pump going out

#2 a chunk of dirt in the line

#3 fuel filter dirty causing low fuel pressure

Low fuel PSI makes a motor run like crap.

#4 water in the gas
