Should my car idle fine....I just put in a 355 with Comp cams XE 224/230 112lsa cam, 1.6 RR, Ported and polished heads with bigger valves, deleted Air pump (smog) and AC...It idles fine when its cold but as soon as the motor warms up it dies and right before it stalls the rpms are bouncing around.....Do i just need a tune or is their something else im missing? Any help would be appreciated...thanks
