Question about 1989 Ford F 150
Is there a way to rebuild the EGR valve???????????
You can try to clean it. Remove the valve, and clean between the valve and it's seat. After cleaning it, pour a solvent (gas works well) and see if the gas leaks past the valve. If it does, replace the valve.
A rough idle when cold may also be caused by dirty fuel injectors. First step to clean the injectors is to add Chevron Techron fuel injection cleaner to the fuel. Use double the strength listed on the bottle. Don't waste money on other brands, they don't work well.
