I usually (never) post here because I usually dont have engin problems like this. Car in question is a 1997 Acura TL 3.2 (V6), ran great until one day it didn't
Quick backstory: Got it from a friend, mechanic checked it out ok, did all my "usual" maintenance stuff (fluids (inc oil filter), belts, bulbs, filters, plugs & wires, PCV...ect. 155,xxx miles.
Car will start fine but idle low, I had it turn off completely twice while sitting at a light. Started right up again and it had been on a while so everything was up to temp. In neutral it will rev freely till redline, no issues. While driving it is very sluggish in 1st up to about 2800RPM then a hard shift into second and all is fine, up to and including 5th gear, rides perfect at highway speeds (70ish). I would really like to get this running right, I just put new plugs in it yesterday, but that did nothing.
