97 dodge ram 1500 with 5.9l. Just did a tune up. Replaced the plugs, plug wires, distributor cap, and rotor button. Runs fine until I hit between 65 - 70. Then I get a sudden studder for a split second. Keeps studdering off and on as long as I am just pushing the gas hard enough to keep the truck at speed. If I press the gas down further it stops studdering and runs perfect. Was not doing this before I did tune up. I also am not getting any warning lights when this happens. Thanks for any help you can provide.
have the same problem?
