my van won,t star after driving locally, i will go to a couple of stoes and it runs great, but if i go to a 3rd place she won,t start, I have put fuel injector cleaner and gas and she starts up , (most of the time ) i took it to auto zone and they diagnose it as spark pluggs and wires ?

That sounds nothing like spark plugs and wires especailly since you said it runs great otherwise.So when it wont start what does it do when you try to start it?Also have you checked for trouble codes in the computer?If not please do that and let me know what the exact code numbers are if you have any not the code descriptions.

Why does the code mean clogged up injectors i have never heard that codemeans you have clogged up injectors.A random missfire could mean a lot of things plugs wires dirty injectors.How long ago has it been since you replaced the plugs and wires?

P0300 is normally caused by vacuum leaks and contaminated fuel
