I have a 1994 honda del sol.... about one month ago i started to get a stutter in it.... it only happens for the first 10-15 min it runs.. while im accelerating.. if im decelerating or in neutral it doesn't make any sort of sputter. and no matter how long i let it warm up i have to be driving for 10-15 min  I've checked to see if it's an exhaust leak and it's not.... currently i have dc headers, AEM CAI, GReddy cat back and Ngk ground kit. and also performance roto, dist. cap,spark plugs and wires.... please someone help.... and just to let you know it started sputtering before i put these parts on but any know how about problems with the parts to would help...
