What is your question?
i have a 98 3 door 4.3 On start up she runs great when she warms up she idols with a slight miss but no codes. it has 215k on it. During slag acceleration she starts bucking after warm up. I have changed Mass air, head to intake gaskets, water pump,
complete tune up done 2 months ago ( 1200 miles ) plugs wires cap rotor and coil. I test drove truck (it is wives truck) and it bucks at slow acceleration and slag. if I stomp it it is fine till I let off the gas. I am thinking bad wire. Is there a way of telling what one is bad?
