Soo here is a couple problems I need help solving

I have an early 89 base model hatch with a 5speed swap done by a shop, still has auto ecu, and the first sensor on tranny is not hooked up (I think it's the 5th/reverse sensor)
bone stock And I bought it from the original owner who was in his 60's
It's also at 180,xxx miles
Regular maintenance always done on time

1)Soo recently I've been getting a throttle problem, I open my throttle and notice my rpms going down and then it goes up, it does this while I'm driving also, can't figure out how to fix it

And sometimes when I turn my car off it doesn't start, it cranks an I smell gas but it doesn't start, and sometimes when it does starts, it struggles then dies again

When my car is on, I slightly move/turn (spin) my injectors and the motor shakes, then I turn it back and it's ok

My car idles at 1500rpms when I turn it on sometimes, and goes from that to below 1000rpms after a bit, but sometimes it does thy reverse, goes from low to high, I've seen it at 2000rpms once at idle

My check engine comes on and off every Soo often, it will be on the off within 10-20 minutes while I'm driving

I think it might be a broken maf but not sure also, or maybe my injectors need servicing, an maybe I need new o-rings, or could it be my ecu? I don't know, I'm new to the Ka


2)My gas light on my cluster doesn't Come on at all,
I drive for at least 50miles once it hit the E and still no gas light on, the gas light doesn't work when my key is in either, I've checked the bulb, it's still new and I tried replacing it, same problem
My open door lights on my cluster is the same problem

3)My speedo moves when I'm just parked and rev a little, it moves with my rev, on the highway I'm going 60 and it will move and show 110, and sometimes it jumps to over 120 and stays at the end but sometimes it stays at 0.
Would a broken speed sensor do this? Or a broken cluster?

Anything would help... I'm new to the Ka but I learn quick and can do any of the motor work myself

How about you split that up into questions and number them.
Also group the problems you think are related together.

1. As far as screeching belts go, check the belts and make sure they are tensioned properly, if not adjust the tensioners (google "s13 fsm" to find the factory service manual)

2. Your problem when accelerating with rpm's dropping and then regaining could be a few things. It could be your throttle position temp has gone bad, or it could be a bad MAF.

3. What do you mean about "turning" your injectors? You mean spinning them? You shouldn't be able to do that easily, maybe tighten them up?

Updated with the numbers and I will try this, anything else fellow zilvians?

And did you mean throttle position sensor (tps)? I'm not finding anything about a throttle position temp, will check this

And I thought top feed injectors can spin easily like that? It maybe not good for the motor though, they only mount top ring and bottom ring?
