1998 4runner 240,000 miles. 3.4L automatic. I bought it 10000 miles ago and did all the maintenance, timing belt, water pump, PCV, fuel filter, spark plugs, wires, Coils fluids etc.
Ran great for 9000 miles ish
Drove to work 1 Morning and parked it. After work went to go get on the highway and had no power. Just about had to floor it to get over 40. Got off the highway right away and limped it home. Put a fuel pump in it and it seems pretty good but not as it was. Can run over 70 but struggles to maintain speed. Cleaned the mass air flow sensor, pulled all the plugs, photos below.
No codes
First spark plug is bank 2 and they all were similar, second pic is bank one and they all looked just like this
I think bank 2 is running lean
Could not find any Vacuum leaks
Thoughts? Any other info I can supply?
