SOURCE: fuel mixture is too lean

many of the late model cars & trucks can't be
adjusted some of the carbs are preset some you can force and some don't have an adjusting screw for the jets if the carb is in good working order but needs a bit more fuel you u must adjust the float for more or less fuel check to make sure the float valve is clean free and not sticking ..

SOURCE: fans dont work and overheats 94 toyota tercel

Most systems work pretty much the same. First check the fans themselves by hot wiring them to the battery. If they work, you need to check the engine temp sensor (some vehicles use one for gauge and fans, others use a separate one for fans) relay, and of course any fuses.
You will help yourself a lot by getting either a chilton or haynes manual to show you how to do testing.

Sounds like the Oxygen Sensor could be faulty, or the fuel delivery system is going haywire for some reason (leaky or plugged injector on some cylinders).

The fuel delivery is controlled by the Oxygen sensor, though.

Good luck on this repair.

2006 Toyota Corolla Code P0171 What could be the problem?


po171 means the air fuel ratio is lean (not enough fuel) so you must check for anything that can do that a good example would be a vacuum leak that allows non metered air to enter the engine (more air same amount of fuel = lean mixture) or a clogged injector (same amount of air less fuel = lean mixture as well)

How to adjust fuel mixture 2 barrel carburater for


In the late 70's they mandated that the adjustment screws be capped over. If they haven't been exposed, there will be two plugs covering them on the baseplate. Air adjustment screws are always somewhere on the base of all carbs with the only exception being on Holley 4bbl carbs used on performance engines (definitely not yours)

Check Engine Light: Code 25 Lean Fuel/Air Mixture


if there is a miss when accelerating i would lean more to the injectors. but if you get the number to your toyota region office ask for an fts, or field tech, tell them what all is happening and that the dealer keeps jerking you around they will probably arrange for someone to look at it for at no charge. i work for a toyota dealer and they are really big on service like that.
