I just bought a 85 Mr2 with 93,000 miles engine has no leaks but tried to get it smogged everything passed accept timing, went to get my timing done and after it was set correctly i lost power i couldnt rev match nothing happens when i hit the gas as i down shift and when i push in clutch it goes to 0 rpms and car dies.. so i set timing back high and everthing works again. I checked my Spark plugs and wires there old and cracked and spark plugs are all black looking so what im wondering is, if i replace them think that would clear up the problem? any help would be appreciated i dont have tons of money right now
