fuel question
car runs smooth when cold and can get rpms to 3500 rpm. as the car warms up it starts to hesitate and have no power. when it get to operating temp it starts running rough then stalls almost like shes starving for gas. i pour some gas down the throttle and it runs perfect then stalls. if i just start the car and let it run it runs for a few minutes then drops idle and stalls. just before it stalls the fuel pump in the rear stops making that buzzing noise then right after that she stalls.
this is what i have done so far
timing belt , crank seal, idle pulley, new battery, slave cylinder.
i put 10 gal of fresh gas and added some fuel cleaner in the gas.
im thinking the fuel additive is causing my problem. my next step is to replace all the fuel lines and filter.but without any manuals im not going to attemp to take apart the fuel dist.
has anyone had this problem before.
