After I drive the car for only several minutes, it starts shaking and stuttering when I try to accelerate. This doesn't stop at all once I start the car and the issue is the same no matter what the speed is. The car doesn't shut off but definitely hasn't gone normal speed. If I accelerate, the RPMs are not increasing normally. When I drive uphill, the issue gets worse. I had the spark plugs checked and found a couple of centimeters of clear oil, yellow in color. What should I do?
As I was reading this I was thinking spark plugs, but you said there was a couple CENTIMETERS of translucent yellow oil? I can’t even imagine what must be happening inside the engine to completely cover spark plugs. I would immediately pull all the spark plugs and compare them to a chart you can easily look up on the internet by searching for "spark plug chart". While the plugs are out of the engine, use a bright flashlight to look down into the cylinders. If you are seeing liquid, smell for gas. If it isn’t gas, then its either coolant or oil. I have a ball of cotton string, and in this situation, I would use it to figure out what fluid that is.. (you can use a shoelace if you have nothing else) feed some sort of absorbant but non-linty sting down into the cylinder to absorb some of the fluid.. pull it out. If it doesn’t smell like gas, and it isn’t oily, it’s coolant. If its coolant, the head gasket is blown. if its oil, there is likely piston ring failure. If there is no liquid in the cylinder, change the plugs and make sure they are gapped properly and give it another shot. If you find you are needing assistance with this, consider a certified technician from YourMechanic who can not only replace your spark plugs but also diagnose the leaking.
