My '93 Jeep Wrangler 4 cylinder has been running terrible. Missing badly. Changed plugs, wires, distributor and finally let my mechanic take a look. He has had the Jeep and was stumped for several days, checking all of the same stuff. Finally, he determined it was the timing chain. Repair will be $600-700 or more.
I have changed many of the parts including alternator, water pump, thermostat, belts, fan, etx. I consider myself semi-competent working on vehicles, and the 4 cylinder seems very straightforward. However, I have never changed a timing chain. Is the timing chain something I can handle? What are the pitfalls?
Knowledgeable advice and experience would be appreciated.
