Car idles rough.. when driving down the road the rpms seem to jump.. everything that has been replaced: fuel filter, spark plugs and wires, cap and rotor, throttle body, and injectors were cleaned.
Get the ignition timing checked and corrected. Check and if needed replace the fuel filter.
You may want to have the throttle position sensor tested. You should be able to buy a Haynes or Chilton manual for directions. A new one TPS is only $60.00. Test before you replace.
SOURCE: engine idle? fuel filter or injectors?
Dont bother with the filter, its under your intake I believe, but Im sure its not the problem. yes, only use toyota plugs and wires
SOURCE: 22RE no power. 240K on body Rebuilt motor w/ 1k on it.
check to see if plug wires are cracked or burnt threw from laying on exhaust manifold
SOURCE: I have toyota camry that has an idle problem...i
did you check the vacumm hoses ? the one on the EGR, high idle means you have a vacumm leak
SOURCE: have an 1986 toyota pick up 22r efi here is what i
make sure you have the right fuel injectors &maf sensor and make sure the timeing is right and firing order is correct good luck
SOURCE: 1986 toyota truck 4x4, 4cyl,
The igniter interprets signals of time and position from the distributor, fits the efi ecu with information and then the ecu gets back to igniter to tell it when to fire specific cylinder, we used to have problems with the distributors and also igniters.

Hello.
The
following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
The
engine and the automatic transmission (transmission control is only
for automatics, engine is still computer controlled no matter the
transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM), which is very rarely the problem. Other
basic checks must be done as well such as mechanical problems with
the engine as well as engine state of tune and mileage on the engine.
The transmission can have mechanical issues as well such as no gear
engagement at all or a failed pump or other pressure related
problems. Also engine mechanical problems ca cause many
drive-ability related problem such as rough idle and other symptoms
