Engine misfireing
New distributor cap,rotor, fule filter,plugs and wires,pcv valve,checked all vacuum lines. Sputters the worst when taking off from stop and when shifting gears on transmission. Wondering if it could be fuel/oxygen ratio sensor? Any ideas? Seems worse in cold weather

Used Borg Warner dist cap and autolite wires and champion plugs. It made no difference at all. Exactly the same as it was before. Havent taken in for diagostics yet. This is the third distributor cap as I thought I might have got a bad one. I permatexed this one to make sure it has a good seal. After 3 of them I have ruled this out. Blazer will run down the road great at 60-70 mph. Its just low speeds putting around town. Thats why I was wondering if it could be an airflow problem or air/fuel mix? Some sensor perhaps. I guess the next step is diagnostics

Blazers are real tempermental coming to ignition parts they tend to only like A/C Delco plugs wires cap and rotor, that being said could be as simple as the rotor not sitting right, But from my experience Delco is what you should have put in
