Runs rough on 1995 GMC Jimmy

Starts but will not run smoothly, wants to shut off, cannot get over 30mph, was rear ended several months back, body is repaired but now doesn't want to run, struggling to get fuel?

look for any exhaust restrictions as that is usually the culprit.make sure the intake duct is clean inside and all clamps are tight.if that doesnt help you might be looking at a healthy tune up like plugs,cap,rotor and fuel filter.
