I have a 2001 Ford Ranger XLT. 3.0 liter V-6 Automatic w/overdrive. 133,000 miles. I have had no problems with this truck until recently. Other day was driving to work & check engine light came on and engine started running rough. There seems to be a vibration in the motor. It doesn't die, there is just a noticeable vibration when the engine is running. I have made a visual inspection of engine & see nothing out of the ordinary. I also replaced the spark plugs. Nothing changed. I understand the most logical thing to do would go have the codes pulled rather than continuing with this system of elimination, but until then, what does this sound like to you? Also, the speedo needle has been jumping when at idle between 10-15 mph. Not all the time, but this started when the engine started running rough. Any ideas?
