if anyone knows... i installed bbk 70mm and stack racing plenum today.
car fired right up (as expected!) and seems to idle fine. after car completely warmed up and driven about some, idle rests nicely at about 750 in neutral. it does first drop to 1000, and then takes second or to to drop to all the way 750. (was wondering if this is normal or not?). NOTE i have not tried adjusting idle (YET).
i did think i smelled something like exhaust (or maybe unburned gas?)in cockpit during my ride, which may be my imagination, but i am pretty sensitive to this stuff. after i parked car, opened hood revved engine couple times, went about 1/2 way to WOT and sounded like i almost got a little backfire?! did i miss something, computer need time to adjust, or nothing to be alarmed about?
also note: i am quite certain everything is reconnected, and tightened. i do have a K&N caik and no other current mods although the exhaust and SCT tuner are next. any help appreciated-
