My beater tends to stall when its cold right after start up unless i feather the throttle for 10 seconds…im afraid it may be worse when the cold kicks in which could be a bit of a issue/hastle. As im keeping the rpms up the second i let off the throttle the rpms drop insanely fast and it cuts almost instantly…Im thinking maybe its fuel related…filter possibly…i noticed recently a drop every 30 seconds or so infront of the tank which is prob coming from my FSU…but ive had that issue 10X worse on my summer car when i 1st got it and there was plenty gas to keep the car running great. The w/e u call it that keeps the idles up after startup does work…I have good spark plugs/wires/fuel filter…fuel pump…a lot of working crap that i upgraded on my summer car that i can use on this car. Any other ideas what it could possibly be? This cars got almost 290 on it…but it still hauls on the highway plenty of punch…recently noticed cracks in the intake after the MAFS…Hmm…? ---

it appears as if my TPS is working…or randomly kicking in…could this be the issue shortly after startup? ---

check your mafs, clean it with a qtip if the wire is dirty very carefully, check your cap and rotor, check your idler thing ---

It was just cracked intake piping bypassing the MAFS. Runs like a charm now. ---

it could easily be the battery or alternator, and a bad alt can kill a batt so possibly both ---
