91 s13 Acceleration Problem

[zfortune]

So when I first bought this car in Sept it ran really good. No problems accelerating or anything. Once I brought it home I did oil change and fuel filter change. Checked the plugs and what not and they're all in good condition. Then I took it out again and it ran really good still. But it's been sitting since then because I was doing body work and some interior work. I just tried to drive it right now and when I tried to full throttle it, it will not go at all. It'll red line easy in neutral but under load it doesn't do jack. Ka24de, manual swapped tranny, not by me but previous owner.
Any ideas on what the problem could be?

My first thought is vacuum leak, check all your hoses. Manual swap should have nothing to do with this.

Does it move at all or does it act like your ebrake is stuck?

oh and it haves AEM intake. Alright I'll check that tomorrow morning and recheck all my spark plugs and wires.

Yes it moves.. It's not ebrake. I just drove around for a couple miles and its just when I give it full throttle under load it doesn't want to pick up and go. Of course if I press the gas the normal way it'll run fine just not full throttle :(

When I went to check spark plugs and wires again I found out the distributor was loose. I made some quick adjustment to it and the car ran a bit better. Just have to re-time it properly tomorrow and see how it turns out.

Edit - My rpm stays at 1500, when I rev it a little bit, for like 3-5 seconds then drops back down to 800-900
