could be the drive gear inside the gearbox, it may just be worn and need replacing. cheers!

low pressure in the tranny, did you check the oil level in park? if so you might have to check it in gear with someone holding it on the brakes, then re-check... hopefully it isn;t the pressure solenoid.... $$$$$$.... they can be expensive, cheers!

Pull the distributor out & examine the o-ring that is at the base of the dist where it slides into the cyl head. If the o-ring is compromised, oil will leak there.

It's a common problem called 'hunting'. It rev's on it's own yes ?

You will have air in the coolant system, it's quite a long process to bleed properly and you must get it right. My advise is have a look on my club www.imoc.co.uk, we have a mk1 section and some fantastic how to's. All your problem's will be covered. check your expansion tank cap for sign's of cracking as well. Mine has just gone on me and has caused the hunting as it allow's air to be sucked into the coolant causing bubble's to pass the temp sensor and give the ECU a false reading wich adjust's the fuel injected.
We are a very freindly bunch with a lot of experience and will be able to help you.

Could be a Fuse or relay

have you checked the fuses?

will be the switch have had to replace for a mate on his

yes

Most likely the fan itself or the fuse or the fan relay, or the fan switch located close to the bottom of the radiator. I would start by jumpering the fan relay. that will confirm the fuse and fan are good.

Its possible that you need to visit some autoshop with scanner or reader codes, they can read the trouble code that was set when the P/S warning was on just by hooking up their scantool, maybe they'd do that for you without having to leave it and they'd know whether there is a bigger problem and schedule it for service at a more convenient time.

Additionally, check fluid level and test pressure from steering pump.

I would suspect a defective positive battery cable.

Get ECU error codes read at your favorite auto parts store (ask nicely). That should give you a starting point. This is the first thing a dealer would do.

if rear wheel drive check the prop-shaft the universal joints may be loose.

ALL auto parts & spark plug mfg sites-- have the gap next to the picture of the plug All plugs come pre-gapped I check mine- but they claim it is not necessary The gap is in your owners manual It may be on the label under the hood
