So, took my 96 on a long drive last night, (about 95 miles) and during the last 5ish miles it started bucking and popping like it wasn't getting fuel or something, the speedometer would buck with it like going 60 each time it bucked the speedometer would either max out or almost max out. Any ideas what could cause that?
I started it up this morning and it is almost impossible to drive. Trailering it home now. I've recently replaced the fuel pump, filter, injectors.

 

Checking for codes is always helpfull in troubleshooting.
CPS ever been replaced?

If your fuel pressure is ok and your spark is ok (check these, don't assume), your CPS (frequent) or CAM(less frequent) sensor can give these symptoms when they fail.
Check your cap and rotor for any obvious mechanical issue.

Just a few possibilities

 

I agree with Roler that you should check the basics first. If you are still without a answer check your wiring harness from the throttle body (sensors) going back around the fuel rail. I found on my 96 that there was a short in the wiring bundle causing mine to buck. If I squeezed or moved the wire just the right way it would almost die. More prone once the wires heated up as well. The way I found it was to just grab the wiring bundle and squeeze it.
