Tons of SR timing problems!!!

[caall99]

at idle, when warm, my blacktop sits around 800 to 1000 rpm. it chooses between those two randomly (???). i tried adjusting my timing, by unplugging the TPS, reving the engine and then shooting the light. when i unplug the TPS my idle raises to 1500 and it won't settle down (reving the engine after unplugging didn't help either). i tried timing it at this new high idle, and trying to "mickey mouse" it until i could get the timing right when the TPS was plugged in. i got it to 15 deg advance with the first cylinder, but after going for a drive and experiencing all sorts of bogging and hesitation at 3000 rpm and 4500 rpm, i checked the timing again... for some reason the timing went to 5 deg advance! :hammer: i am totally lost. i can't seem to get my idle right, nor my timing. could the TPS be bad? or could a dead coil pack be the culprit here??

anyone know a more "overriding" method of timing? then again i should probably fix the high idle problem first..

any help would be sweet
