I have a manual transmission 1994 Mazda B2300 truck. It has been having an issue with fuel delivery as it will idle well sometimes and sometimes not. When I am driving, sometimes the engine will run smoothly and the gears will change smoothly. Other times the engine has a muted kind of a sound and the gears are rough. Sometimes the check engine light will come on during this but will go out after a couple of miles.
Recently, I was pulling away from a traffic light and when I changed into 4th gear, the engine revved very fast, as though the accelerator was pushed to the floor, and wouldn't idle down again. I re-cranked the truck three times over about 15 minutes and each time the engine revved very high and wouldn't idle down. When I went back to the truck more than 2 hours later, it cranked and idled down as it should. I don't know what would cause that to happen and would appreciate any help or advice.
