About 3 months ago, I replaced the spark plugs on my 1999 Jeep Wrangler with a set of Bosch Platinum Plus plugs. The engine shortly after started to tick loudly whenever the engine was under load (going up a hill, pressing on the gas in 5th gear). I replaced the Bosch plugs with Champions, and found the Bosch plugs were scorched and burned on the ceramic part of the plug. I replaced the spark plug wires as well. I haven't replaced the coil or distributer cap yet. Any ideas?

Start with the basics...meaning check the spark plug wires and spark plugs. While under the hood, inspect all hoses for a vacuum leak(s). Then turn the ignition key on-off-on-off- on...leave in the on position and write down the number of flashes the check engine light indicates....2 flashes = #2....pause.....3 flashes = #3.
Let start from here. Are you able to perform engine repairs or diagnostics???
Ticking is generally associated with a valvetrain problem but may be caused by low oil level or pressure. Noise is in the upper half of the engine. Knocking is from low oil pressure and is caused by worn bearings causing pressure loss. Knocking is the worse of both conditions (means overhaul or engine replacement.) Ticking needs to be checked for it's cause...if cause is low oil pressure, remember...oil pumps don't cause low oil pressure, pressure will lost if bearings are worn or pump inlet screen is plugged with carbon.
Amelia, we just bought one off a lease 5 weeks ago (purchased from a dealer). We are having the same symptoms, suddenly, as you describe.
Took it back to the dealership. After a bit of drama, they agreed to foot the repair bill ($1000). It was a broken distributer cap and wiring which should have been replaced before it was resold to us. What a pain.
I would do a complete tune up before I did anything else. Some times on chryslers just a bad spark plug can cause a lot of greef. I would start with replacing the plugs (using the bosch platinum plus 2) , wires, distributor cap and rotor. See if this works for you. If not write me back and I can tell you more info..
Also if this doesn't work for you I need to know what motor you have 4 or 6 cylinder engine.
