I purchased a 91 Mazda 323 1600 sohc Auto, had to weld plates on rear shock towers for a safety , engine idles rough, replaced plugs and wires but found cap hold down screw was snapped, fixed with a c clamp but Still misses , will change cap and rotor soon, hope that's the prob, when I fix this problem I would like to get more power which it desperately needs, what should my first upgrade be?, or just get used to being tailgated a lot and getting unapproving facial expressions from considerate fellow motorists, car has 122000km ,
