I would first start by changing trans fluid & filter. It should be done every 30k or 3 years.

Unfortunately the only was to get to the tank is to lift the car high enough to drop the tank down enough to unhook necessary lines and electrical connections to the pump. Once you lower the tank, a few rubber line connections and electrical plugs. Mechanical level 1 - 5, this would be a 3.5

Look at the plug. Is it full of oil? If so you have an oil ring problrm on that cylinder. More likely though you have an ignition problem on that cylinder. Check dist cap, rotor, and plug wire. If that fails, check compression in affected cylinder.

Newer cars can have the check engine light come on if the cap isn't on right or sealed properly. Start by getting a new gas cap. NAPA or most other parts stores would be able to get you exactly what you need.

The water pump is driven by the timing belt, so it is best to change that too. If I remember right the V8 has 4 cam shafts and uses a hydraulic tensioner. Since you have to precisely line up all the timing marks on the cams and the crankshaft, This job is best left to a person that has a good knowledge of this engine or a better than average skill level. failure to install the timing belt properly may result in extensive engine damage.

The procedure for timing belt removal is as follows: remove the accessory belt(s). turn the engine by hand so that cylinder #1 is at top dead center. You should have timing marks on the crankshaft ulley and the timing cover. remove the pulley. then remove the timing covers. You will have to support the engine from underneath as you need to remove the engine mount to take the belt off. INSURE that all the timing marks line up and rotate the engine as needed to achieve this. Take the belt off and then you can remove/replace the water pump. Install the timing belt and isure that all the marks line up after you reset the tensioner. Rotate the engine clockwise 2 full turns and check all the timing marks. If any are off then re install the belt again. After that put the timing cover back on and install the crankshaft pulley. then install the belt and fill the radiator. run the engine with the radiator cap off until tthe thermostat opens and add water to the right level.

If you haven't changed it in years it would be good to go ahead and do, it will likely save you many headaches down the road.

If you are unable to do it real soon and you haven't checked your transmission fluid level in a while, I would make sure it isn't running low. generally low fliud level can cause some slipping to occure.

I hope this helps you.

Probably time for a salvage engine swap after about 250,000 miles.
Having it rebuilt is an option because as long as you have not damaged the crankshaft, it should not cost more then $2000 to have it rebuilt to as good as new, by a reasonable shop.
But avoid dealers if possible.
Japanese engines with low miles are very inexpensive however, because of the high tax on cars over 5 years old in Japan.

If you are talking about the temp gauge, this could be due to an airlock in the cooling system, a blocked radiator, a work water pump or even a faulty gauge. You may also find that the voltage regulator (inside the instrument cluster) is faulty and giving a higher voltage to the gauges then required. This can also cause the gauge to read higher then normal.
Have these items checked by a qualified person.

Code 71 says EGR problem.
Clean the EGR modulator valve.
Replace the EGR temp sensor.
If this don't cure it check the EGR valve.

are u doing a brake job?..is it the calipers that are stuck?....try using a big C clamp to slowly push in the piston(s) if that is the case.

If they are completly rusted, u may need new calipers
