Help! Everything I do makes it worse.
I have a 99 F350 with 130k. It does not get used much. It is serviced reguraly.
After driving about 5 miles it started running rough. I accelerated and the service engine soon light came on briefly. I limped home. Upon removing the air filter I found it extremely dirty. I cleaned and reoiled it (K&N) and reinstalled it. No real difference, still running rough. I disconneted both batteries and changed the fuel filter. Reconnected batteries, started truck. It idled fine, very smooth. As I started to test drive it, it began running rough. When turning around to return (about 1/4 mile) it died and will not restart. I checked the fuel filter installation and found nothing wrong.
Any advise, other than to let someone that knows what they are doing work on it?
Also, I do not have access to a scanner.
All help and advice appreciated.
