Alright,
Got a fuel system problem on my 1991 Toyota 4Runner, 3L V6 (3VZ) Petrol.
Keen on hearing some opinions.
Recently went on a big 4wd touring trip and tackled some seriously steep, rocky hills. I pushed it hard up a hill, bouncing around everywhere and it started missing pretty badly. Turns out I stirred up all the **** from the bottom of the fuel tank, sucked it through the lines, clogged the filter, blocked the two center injectors fully and pushed it 250 k's home running on 4cylinders (thankfully no piston damage etc).
I took it to my mechanic when I got home who has done the following:
- Compression test, all A-ok (RHB 150/120/158, LHB 145/115/150)
- flushed all lines
- replaced fuel filter
- Cleaned/replaced seals/flow tested injectors
- Drained tank twice
Got it back and was running fine, not 100% as it was before, but back on 6 cylinders and on the whole quite smooth.
I've just run half a tank of 98 in it, and unfortunately in my haste, I ran the tank a bit too low and it just started slightly missing again.
So, I'm assuming there's still some **** in there. I'm planning on doing the following:
- Replace fuel filter
- Run some Injector cleaner through the tank OR; Nulon Petrol Injector Cleaner - 300mL - Supercheap Auto Australia
- Run this through Liqui-Moly Fuel System Cleaner/Conditioner - Supercheap Auto Australia
If that doesn't work, I'm thinking drop the tank, completely clean out and replace fuel pump.
Anyone have any suggestions of what else to do or confirm what I'm planning is sufficient?
Thanks
