Remove the air cleaner and look into the throttle body and see if there is gas coming out both injectors.If only one is working then switch the wire connector from one injector to the other.This will tell you if the injector is bad or if it is not getting a signal.Check for good vacuum at a good vacuum port.Should be close to 20 inches of vac.If not then this could be a good sign of bad timing or plugged converter.Hope this helps.Good luck.

Sounds like you have a vacuum leak. When the engine is cold the leak is there but as the engine warms up the parts start to expand thus closing the gaps and sealing the leak. I had this problem on my personal vehicle and it turned out to be lower intake gaskets.

is the check engine on? are there any trouble codes? one posible cause would be a restricted fuel filter, a worn fuel pump, or a restricted exhaust system.
