Bought this DB2 about a week ago and was just wondering on some tune up parts, being it is not OEM. The motor is orginal b17a and ys1 tranny. Has a 97 GSR head and skunk 2 pro manifold with some throttle body i dont know of in which ill take pics of tomorrow. My questions are which plugs should i run? 97gsr or 92-93 gsr plugs. This goes for wires to, it has some ungodly big “race” wires that i want to swap for some ngk blues. He claims to have a chipped:base mapped ecu but i havnet gone that far yet. My Issue is that sometimes (i mean once every other day if that) it feels sluggish or misses while highway driving. But, once i get on it it clears up. Note: the car was sitting forever cause the previous owner never drove it and needed a jump to get it going (no jumps ne more). Could it be impureities in the fuel system? Vehicle idles perfect, no starting problems fires up first time every time. Gimmie some input. soon as i get info on plug/wires ill start there.
