Question about 1985 Toyota 4Runner
Problem appeared over-night (about 2 months ago). Regular pedal depression yields almost no acceleration. Floor-boarding it or nearly so, gets very slow acceleration to about 12-15 mph, then it acts like it is in passing gear. Must let off pedal at about 25-28 mph to avoid over-reving engine. Letting off, it shifts, and speed starts to drop. Then have to nearly floor again it for it to slowly (again like it is in a lower gear) accelerate to 35 to 38 mph. Letting up, it will shift to high, but speed holds or starts to drop slowly. Need to nearly floorboard it again to get over 40 mph and again it feels /sounds like it has shifted to a lower (passing?) gear. Sometime it reaches high 40s mph downhill. Generally 38-42 is top end.
A shop tweaked idle (air?) mixture for this injected engine and said it was OK now, after road test. He advised replacing fuel and air filters. I replaced the Air Filter & found old one was clean. Have a new frame mounted fuel filter, but cannot find old filter on vehicle to change it out. On-line search suggests there may not be one on vehicle. It is consuming lots of gas driving like this.
Some VW friends suspect it may be the transmission - which neither of us can afford to repair.
Any ideas please?
From minor problem to major problem. Try to replace your spark plug wires, rotor cap and the spark plugs, also it can be the injectors, plus if possible, try to replace the fuel filter which is located low under your EFI unit. If problem not solved, then it will probably be your A/T trans.
