any hot start problems? if so check pressure regulator vacume side for fuel . Any corsion on ignition coil towers.Check engine light? EGR?

Could be coils (actually going bad even though not corroded), or also might be Throttle Position Sensor.

if the trans was going bad i would think it would have a noticable rpm increase when the power is going away because it woudl be slipping...





when was the last time the car was tuned up? a throttle response issue could certainly be somewhere in the firing system...which a full tune up could fix.\


how long has it been doing this? just recently, like since the last fill up? it could be bad gas...Edited by: Patrick

Maybe an air intake clean may help. Juste shooting carb cleaning in the air intake butterfly often help a lot.
