Loss of power for short times

I have a 92' DX and it seems to have a prob. It has been sitting out, not working for a year. I finally got it running but not like it was. When i'm driving and then shift, after i let off the clutch and give it alittle gas it bogs down. I have a cat-back and when it happens it sounds like the exhaust is stuttering. It only last for a few seconds and then the car will accelerate normaly. This happens half the time im driving. Please help. Thanx.

Sounds like water in the gas or bad gas. Try draining the gas and refill with fresh gas and drive it around for about 20 mins and see if that helps

could be your throttle position sensor. give that a check.

Ok, Ill Try those but i also found some kind of liquid on the spark plugs in the valve cover. Could that also be a reason?????

What does the liquid look like? Oil? Water?
