hesitation and dying

[taker73044]

ok heres the problem when i first start my car i have to hold the gas for a min or so. then it will idle after i let off but it idles rough. After it warms up it smooths out.seems to still be a slit miss thoo. now when it is idling if i rev it you can barly hear it hesitate. have to listen real close to hear it. now when i get it on the street she drives fine but when i accell hard from a stop she spudders and dies
also if i accell hard while moving she spuders for a sec or to then picks up. if i power brake she will burn the meat off rims lol but when i let off she dies. i have re droped the dis. tons of times to make sure i had it right and i do droped it at 0 tdc pointing at #1 also tried what chiltons man. said that was to set it tdc then move it to my timing mark 10 btdc then line up the stator in the dis. and piont at #1 so i know its not the timing.


Note: no backfiring has been noticed

is the car with you right now? if your able go pull the air filter off real quick and start it up...see if it is just getting starved for air. sounds to me liek to much gas is getting dumped into the cylinders.

 

[taker73044]

brb got to go get wife at work.

 

[ryan218]

she idles at 1200

maybe knock it down to 1,000 and see how the throttle response is from there when you get on it....im starting to run out of ideas lol

 

[taker73044]

knocked it to 1000 still same even with no air cleaner
