2000 Eclipse acceleration problem

I have a completely stock 2000 Mitsubishi Eclipse GT with the 3.0L v6. Recently I bought the car from someone who said it just died on the highway and wouldn't start. After getting it home I looked it over tested the fuel pump and it was fine. Later I found a severed wire going to the crank position sensor. After getting it reconnected it started just fine replaced the distributor cap and rotor too. New I'm noticing it has very slow horrible acceleration. It runs a little rough at idol and doesn't sound bad during acceleration. What could the problem be?

My first thought when an eclipse "dies on the highway" is timing belt. Thinking that, I would have gone snooping around the timing cover area and like you, found the CAS wires disconnected. Plug it back in and it starts :scratch:

So why'd it come unplugged? My bet is the timing belt managed to grab the wires and sling them around a sprocket, pulling the plug out and, at least, damaging a wire or three and at worst, (since it still runs) caused the timing to skip a tooth or two. The GT WILL run slightly out of time, but will present the symptoms you report.

But start small. Anything that you had to touch to get to the cap/rotor, I'd recheck. Connection of the intake to the throttle body, PCV hose plugged back into the intake, MAF plugged back in, etc.
