From what you descibe I think it is the air mass sensor in the air intake pipe after the aircleaner. try unplugging it and then driving the car, if this make differance to the performance then thats that but it could also be the exhaust thats blocked.

leaks out where the resivore or lines or the steering box which ever it maybe you will have to replace.

If your var has 55 fitted as standard then it is very possible that you have a fuse problem. In a lot of vehicles to run such high wattage bulbs create a lot of heat and as some refelectors are covered plastic they tend to melt. If how ever you have good refelectors and still wish to run 100 the I suggest you put a relay in the system and take the load off the circuit. Use the exexting head light wire to activate the relay and run directly from the battery( use a fuse in this wire)

There are two sensors. One is called the pre-cat sensor part# 0015406017 and the other the after-cat sensor part #0015403717.I don't know where you live so can't tell you any specific websites. But the o2 sensors list for about $248 from the dealer. You can buy these aftermarket for about $50 for a Bosch sensor.

Check your power steering fluid. Screeching will come from the fluid being too low and would affect the steering. It will also burn out the pump if you don't keep it full.
