1994 full size blazer 350 odd miss
 

I have a 94 blazer with 235k on it and owned it since 200. Ever since I have owned it it had a miss and would loose power and almost stall. This would only happen when you give it gas while turning. As soon as you would straighten up all power was back and running great. In the last 500 miles the miss now has came and gone but getting worse, tried all the normal issues plugs wires rotor noting has helped but I am convinced it has something to do with the turning issue? Any input would be great.
