I have been browsing and checking the site since I got an 89 Golf CLi A/T last week and I have some questions. Hope you could help me

1. Acceleration - Its slow in acceleration, at the start. Is this normal?

2. There is a kick when you put it in drive, much like when a train starts, is this normal or I need to replace an engine support? When the engine is cold also, there is a strong vibration when you slowly accelerate. When the engine is hot it hardly vibrates

3. I need to replace speedo cable, I read in another forum that you just remove the clips and use a universal speedo cable and re-attach the clips since the part is not manufactured anymore and hard to find. Has anyone done this already?

4. Is it okay to have the headlights cleaned? I'm afraid the glass might break if they open it.

5. How many amps is the alternator have? I believe I still have the stock one. If I want a higher ampere, where could I find one?

6. Is it safe to have it engine washed? The previous owner never had it washed. Its a K-Jetronic engine

7. On my way to out of town yesterday, my oil indicator light up and alarmed when I was slowing down, I revved it up and it was gone. It happened 3 times. I'm not sure if its because I ran an average of 3.2K RPM (my speedo is busted) for 25 kms straight on the highway. I checked the oil before we left and it was max level. I just check it this morning and its still the same. Also I'm also hearing an revving RC toy sound when I rev up beyond 3k rpm

Can I assume that the oil indicator is also the check engine light (CEL)? Thanks!
