Maybe a spark or cam timing issue, or srticking intake valves.
With the mileage on the vehicle, it's time for a new cam belt & with the mileage, intake valve carbon deposits also belong on your suspect list, especially if it's using some oil.
So maybe begin with a cyl balance test, followed by a compression check on at least the & suspect cyl's the balance test has flagged, if not on all 4 cyl's.
Let us know what you find.

Thanks for the replies guys. I haven't done anything with it yet but I'll look into the tests you guys mention.
Two other things:
1) It has had like 2 periods where it sat outside for 6 months straight without being started. Maybe even a year one time.
2) If I pump the gas peddle, I can get it to accelerate higher without bogging down. I have to finesse it really. Pump the peddle slightly until it starts to bog, let go, pump a little more... and each time you can increase the RPM until eventually it's high enough to put into gear.
When it was stored, was fuel stabilizer added at the pump, before filling up & was the engine run long enough to distribute the stabilizer through out the fuel system????

No, nothing of the sort. And come to think of it, it ran fine before the periods it sat. It sat through winter too. But I'm here in FL, so maybe not too bad?
