My dilemma is, switch out the oil, then spark plugs wires etc next week or so.

orrrr wait and do the oil change after.

whats better?

 

Do the plugs and wires while the oil is draining

 

If it was me,and i just got a vehicle. Id buy cheap oil,and a bottle of seafoam and run it until you get the tune up that next week,then change it again with good oil and filter.

 

Well i decided to change the oil today. spent like $22 bucks or something, but its better than before. i noticed my overall oil pressure went down a little, (used to be at halfway mark), now its a quarter or above. But i can tell you its not running too well right now. It bogs and sputters whenever i accellerate sometimes, and when im cruisin a solid 40-50, i can feel my engine sputtering/bucking almost.

Think it could be the fuel pump or filter? Im also wondering if the carb needs a sweet tuneup or a new one in general.

 

Is it carbed or tbi?

If its bucking,if its carbed id definitely have it rebuilt by a reputable builder. It'll help weither it be the issue or not.

 

Plug or wires is my guess
