Answer 1
Is the transmission slipping? What does the timing read, this car has a Distributor. Does the timing advance? Does the car misfire? Are the mechanical injectors flowing properly? How is the Fuel Distributor? Is there rust or contamination inside of it? here is a link to a site with repair manual info for your vehicle, there is a small fee but it is well worth it. http://bit.ly/mitchell_repair_manuals_online -

Sorry i was on vacation.1 trans is OK, 2 no misfire, 3 fuel distributor has been changed, 4 dont know what the timing read. The car starts up on the first turn and runs just as smooth as heck you can driven it but when you press the pedal it bogs. and thanks for your reply -
