QuestionTed, The 5SFE Calif. engine has no "Air Flow meter". Instead it has:
Electronic control parts:
Intake Air Temp. Sensor, Vacuum Sensor, EGR Gas Temp. sensor, EGR VSV, Water Temp. Sensor, Cold Start Injector Time Switch, Main Oxygen Sensor(exhaust system),Sub-Oxygen sensor,(exh. Syst.), EFI Main Relay, Vehicle Speed Sensor,and ECU.
On the Throttle Body it also has a: Throttle Position Sensor, Idle Speed Control Valve, Auxiliary Air Valve, and a Throttle opener.
It seems, the 5SFE Calif. engine performs the same functions that the "Air Flow Meter" would, but in a different way using different components. Can you tell me which of the components that it has are relivant? P.S., I also got some additional improvement by replacing the Air Filter box lid inorder to get a new Intake Air Temperature Sensor Seal that only comes with it and the PCV hose.-------------------------

1990 Toyota Celica GT., 2.2, 5SFE Cal.Eng.. Follow up Question: Car pulsates on aceleration and deceleration and will self energize into severe bucking when at minimum throttle above idle and minimum load. Previously, I changed: plugs, plug wires, cap, rotor, air & fuel filters.
I got a 75% inprovement after performing your recommendations. I replaced the cracked air cleaner hose, upgraded the wire hose clamps to strap clamps, checked the filter box for cracks, snugged up the filter box mount/seals and repaired the air leak at the coupling on the intake side of the air filter box. Now the problem is much less severe, but the car will still self initiate a self-energizing pulsation that will increse into severe bucking at minimum throttle above idle when under minimum load. It will now smooth out if I take my foot off the throttle or disengage the clutch. Also, 6 mo. ago, I had new eng. mounts installed. What do you suggest next?
Answer -
You may have to replace the airflow meter to correct this problem.
AnswerYou must have a late 1990 or 1991 model because according to the factory manual the '90 had an air flow meter.
Remove the distributor cap and then the rotor and the coil cover, check the coil for any cracks or burned areas, it's the only other thing I can think of that won't turn the check engine light on.
