1985 4Runner 22RE (injected / auto trans) has NO accelaration.
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.

are you having any difficulty putting it into gear, if is auto trans? Had a problem with no brake lights,2004 Aveo, there is a plunger switch that engages when you depress the brake pedal. if you get on floorboard under the steering wheel area, depress the brake pedal you will see the switch the brake pedal should be engaging. It is simple to remove, take to your auto parts store, they should have one in stock. Good Luck
Sounds like transmission fluid and filter needs changing. It's one of the most overlooked maintenance items. Trans fluid and filter should be done every 50k miles. If you tow a trailer should be done 30k. (I assuming this is an automatic transmission. You didn't say)
to reset the check oil light on your car. First put the accelarator pedal to the floor , then while holding down pedal turn the key to the run position without starting vehicle, now quickly pump the accelarator pedal 4 - 5 times and hold pedal to floor on 5th pump. Wait for check oil light to flash then turn off key and remove it . Repeat if neccecary
I have a jeep wrangler and to have it towed you are suppose to put the transverecase in neutral after you first depress brake pedal put trans in neutral then start engine shift auto trans into drive release brake pedal make sure there is no movement, shut engine off with key left in acc position shift auto trans into park, disconnect neg battery cable (damage can result in trans if shifted into park while transvere case is in neutral with engine running) you should refere to your owners manuel
1990 22re same problem surge when pedal was depressed thought it was booster or check valve still didnt fix it i even put a brand new booster on it just to make sure still no fix it finnally went away on its own for about a month now it does it just sitting at an idle with out the brake pedal depressed traced all vaccum lines no problem there and still have no clue
have fuel pressure checked if ok should be approx 60psi.if ok try disconnecting mass air flow sensor connector to see if problem is eliminated. this the computer in to a default mode.the sensor is a common problem.thanks from schleck
