I have 2006 Ford Ranger manual 4 x 4 sport, with 160,000 km (100,000 miles) that I bought back in August. It had brand new spark plugs and wires done recently. It ran well until yesterday. I drove a few blocks when I noticed when I accelerated there was little power, and it was idling rough. I drove it back home and noticed there was this black soot coming out of the exhaust. I had a friend who borrowed a code reader and it showed the codes P0300 P0301 P0305. I don't have a lot of money, so want to have a little knowledge of what it could possibly be before I take it to a shop.

 

P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0305 Cylinder 5 Misfire Detected
A random misfire code usually means the air/fuel mixture is running lean. But the cause might be anything from a hard-to-find vacuum leak to dirty fuel injectors, low fuel pressure, a weak ignition coil, bad plug wires, or compression problems. Even a dirty MAF sensor can cause a lean code and/or misfire to occur.

 

Since this happened a few months ago, can you update us if you fixed it?
