89 4Runner shutting off when coming to a stop

Hi there. I just picked up an 89 4runner, 22re, manual two days ago.
The truck basically sat for 9 years. It only has 296000 KMs. It has been working well for something that hasn't touched pavement in a long time.

BUT. I am having an issue with it shutting off when I come to a stop. I have figured out that if I give it a little shot of gas every few seconds it will remain running, and it idles a little rough. I have already adjusted the throttle cable, fixed my battery terminals, I put some fuel stabilizer in it before I even drove it home. My last guess is my fuel filter but I am no mechanic. Has anyone else had this problem and what would be the best way to access the fuel filter?

Second question. It quite obviously needs its oil changed, but the filter seems to be in a tricky spot. Any tips for getting to that?

Thank you, cheers!

 

There is a "hatch" under the rear seat, on the passenger side, for accessing the fuel pump.

For the oil filter, the easiest way is the large screwdriver method.

 

You might want to look at the plugs & or wires. The plugs might be rubbing the header or be close enough it melted the outside?? Good luck.
