thanx for all of your help fellas, turned out to be a combination of things. me and my buddy replaced the 24x crank sensor. MIL went off for 5 min. and flashed back on, indicting a misfire. so i drove right to "the zone" and had the code scanned. came up, i believe p0306(pretty close to being the same as other code) I had replaced the spark plugs after doing the head. well, the plug on the #6 cylinder had a crack in the porcelain!! rushed right to parts store, got a replacement plug, and boom baby! also cleaned throttle body out, so now she runs better than ever!! my need for speed is now fulfilled once more! still have a new fuel filter and plug wires to put on anyways. now i'm once again focusing on mods (air intake, perf. exhaust). thanx again!
