You may check out your intake valves and try to clean them up if they are caked with deposits. I scrubbed them with acetone but did not get as much off as I would like. A walnut media blaster is likely the way to go and I will probably do this when I try and do it again. CorkSport sells one for a decent price but some people make their own. If your generation Mazda is port injected then this is probably a waste but I would still inspect them.
