RE: Trouble codes
I already answered you via PM, but this is good general info for the forum. Your car has a crank position sensor, linked to a computer that sends a "fire" sgnal to eight individual coils, one on each cylinder. No rotor, distributor cap, points, ect. Your S500 has two 02 sensors, each located on the lt/rt manifold pipes.
Cars that sit for extended periods develop three problems that can be easily remedied:
1. oil goes bad, water condenses ito it.
2. fuel goes bad, water condenses into it and octane levels drop.
3 fuel injectors can stick either open or closed.
For a car that has sat for months, drain and change the oil, drain and refill the fuel tank and add a dryer to the new fuel. The worst part is when the engine first starts, no oil film on the bearing surfaces. If you can, disable the crank sensor pickup (not for the novice), then the engine will only crank via the starter, pump oil through out the engine.
As for the injectors, buy a fuel additive and use it for the first three or four tank fulls.
O2 sensors don't fail that often, and when they do it doesn't really effect the performance of the engine, especially missing. You might run a bit lean is all, and have the "check engine" lamp on.
By the way .. if the battery is dead, never, ever use a booster. Trickle charge it at best and if over 8 hours the car won't start, get a new battery. Boost voltage can be as high as 18 volts, can really fry some unprotected systems such as the starter.
