XJ Ask the Question Thread
There's a layer of oil and gunk built up on the underside of my engine. I'd like to clean it off to see where I'm leaking. Since there's a lot, should I use something harsher than normal degreaser, or should I just stick with it?

Use standard degreaser such as purple power. Cover all electrical components and accessories such as alternator, battery, etc. Spray the degreaser and soak it down and wait for it to dry before starting it again.

I just bought a 2001 Cherokee sport and I replaced the spark plugs. After that the car began to shake upon starting. Then I put old spark plugs (in good condition) back in and it ran fine. Next day I drove it around for about 20 miles then took it to "u pull it." It drove perfect. When I attempted to leave the car wouldn't start and when it finally did it cut off like it couldn't get power. I spoke with a mechanic they said it could be the coil pack?! What do you think
