Engine Performance problem
1985 Pontiac 6000 6 cyl Two Wheel Drive Automatic 185000 miles

For the past couple of days, my engine has been making this knocking sound when I start to drive, it also keeps shutting off when Im at a red light. I took it to a mechanic and he told me I needed to get an air filter, rotor, spark plugs and distributor cap because it kept accelerating and wanting to cut off when Im also at stops or red lights. My obvious question is what's wrong with it. The mechanic didn't give me an answer he just said that I needed all of that. I need to know if it is my engine that is getting messed up and what I can do?

Do you
have the same problem?

If its knocking in the engine it will be there all the time or vanish as you increase speed and comes back when you decelerate- Now if its knocking only under hard acceleration could be pinging/detonating-due to engine overheating, an EGR valve that's not opening or the knock sensor is not retarding the ignition timing
