I have a 1984 Mazda B2000 2.0L 4 cyl 5 speed, 2wd truck. It has 120k miles.
Over all, it's in good shape and runs pretty well.
Lately, when I accelerate and press the gas down, in 3rd, 4th and 5th gears, 40 - 60mph it will start to diesel and chug and lose power when I press the gas to the floor to accerate. I have to back off the gas and hold my foot at 1/2 to 3/4 for it to regain it's composure and cruise at 55 - 60mph. It runs fine at lower speeds, 10 - 45 in 1rst - 4th gears.
Any ideas what might cause this? Bad wires? Sparkplugs? Gap? Or, could this me more involved?
any ideas, comments or suggestions for troubleshooting this would be a great help.
have the same problem?
