Truck Misses At Low RPM
I have a 99 ford f150 and when it is in low rpm it jumps and misses. When i put in nutruel it is fine, but when it attempts to go at a slope it misses. I had the intake gasket changed and the spark plugs. When we opened it up it had water/oil where the spark plugs were. We think it could be a cracked head or head gaskets.. i just needed some f150 pros opinions before we pulled the motor..

Did you make sure all the plugs are good? I know there new but so were mine and one of them failed(dont buy champion) Check the injectors to see if there working. Put a long flat screwdriver on the end and put your ear on the handle to see if its clicking. Also one of your coils could be shot. switch the coil around or unplug it see if the problem gets worse or stays the same. that will narrow down the cylinder
