today i turned on the my car and it was stalling and then i stopped. when i got out of work it happened again. I took the car to autozone and had them scan it to get the error codes and i got P300, P303. The guy said that it could be the "bad gas" or the ignition coil. I purchased the ignition coil and installed it. The car is stalling. Does this car have a fuel filter? I have never changed the fule filter since purchasing the car. Can it be something else?


Thanks

 

Yes and yes. It has a fuel filter but they are designed to last the life of the van eg., my 96 still has the original with 210K+ miles. It's above the fuel tank. Bad gas? Slim chance but wouldn't hurt to run a tank through it from another station. Maybe even a bottle of injector cleaner. Of the two codes the P0300, random misfire, is the primary concern. Something is effecting multiple cylinders and there are many possible causes. Vacuum leaks are at the top of the list. Could be from a cracked vacuum line or the EGR valve could be sticking open. Was any maintenance done recently that could have induced the stalling? Which engine? Is it stalling both hot and cold? Here's a little background info:
