Check engine light came on. vehicle will sometimes shut off after first started for the day when I go to pull forward or reverse, doesn't want to go above 25 MPH. lags on takeoff and acceleration. Doesn't appear to be caused be sticking brake (I state this because I have a small brake fluid leak, but keep fluid checked and filled regularly). Just bought new ignition wire set and got first 3 installed no problem. So my question is, is it easy to remove and then replace the top back part of engine to replace the last 3 wires? And other than fuel filter what may be causing this performance issue?

Hello.

Firstly you need to get the car scanned to see why the check engine light came on ? most car spare stores will do this for you.

This video explains how to do the rear 3 spark plugs. and I've added a couple of diagrams below also:
