Unsteady idle and clatter on hard acceleration
Engine clatters when I get down on it and thing always idles rough/unsteady. It's been doing this since I bought it at 11,000 mi and now has 154,000. I quit running ethanol in it which amazingly enough, it wouldn't clatter when I ran E85. Still idled rough though. I try to use Shell or Chevron when possible. Mileage isn't too bad. Also, it only does this when motor is warm/hot not in morning when cold.
Why don't one of you nice chaps come straighten this out for me I'm in Spring, TX and need a mechanic I can trust anyway.
Edit: I noticed yesterday it does it even under normal acceleration but weird thing is not all the time it seems. Sometimes barely audible.
