Restricted performance light came on after emissions testing and the car cannot be driven at speeds above 45 MPH without lurching. Do you know what happened with testing? Thanks. Walt Drubka

Check out the videos. Also drop a bottle of Fuel System Cleaner to a quarter tank of gas.

limited info generic answer ---wont complete the test ??? need more clarification --is the obdll not communicating --or is it failing do to not ready conditions --as to the way you wording your question would suspect some kind of ecu failure or harness

You must perform an OBD2 drive cycle to make ready for testing.
Toyota Drive Cycle for Setting Smog Check Readiness Monitors

• Fuel tank at 1/2.
• Engine cold start idle for 10 minutes.
• Drive at highway speed 55-60 mph with steady throttle for 16 minutes.
• Return to idle for three minutes with engine running in park.
• Drive again at medium speed 40 mph for eight minutes.
• Return to idle for three minutes.
• Repeat next day.

Take extra caution while performing dirve cycles on public roadways. Drive cycles can be difficult to follow under normal driving conditions. Begin by: - Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on. - Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. - Hold at a steady speed of 55 mph for three minutes. - Decelerate (coast down) to 20 mph without braking or depressing the clutch. - Accelerate back to 55 to 60 mph at ¾ throttle. - Hold at a steady speed of 55 to 60 mph for five minutes. - Decelerate (coast down) to a stop without braking. If all other emissions systems are functioning properly, completing the drive cycle above will set the "readiness flags" required to pass the smog check. It will not hurt to perform the drive cycle 2 or 3 times before the smog test.

If I'm not mistaken this is an old car? The answer may be in a good service and clean up of all the emission control valves and hoses?

you should not have to worry about it with the age of your car. nothing is wrong take it somewhere else to be tested

After checking and adjusting the tire pressures, The vehicle must be driven at speeds above 28 Mph (45 km/h) for approximately 20 minutes for the TPMS to receive the updated information from the tire pressure sensors in the tires. It will then reset itself.

If you have driven the vehicle, and the indicator will still not go off, then you need to take your car in for service so the malfunction in the TPMS system can be properly diagnosed.

if you are failing emmissions test your evaporator canister is expired replace it and then you and your car will get a green light

Wasting your time driving it
Check for codes
Look at all data
Find a problem & repair

Have exhaust gas reading taken in a repair
shop, & use that to diagnose and repair

Some vehicles require very specific drive cycles (called "drive traces" if you perform them on a road simulator or dyno) to activate certain self-checks like the catalyst and EVAP monitors. As a general rule, doing some stop-and-go driving around town at speeds up to about 30 mph followed by five to seven minutes of steady 55 mph highway speed driving will usually set most or all of the monitors. Consequently, if you're checking an OBD II system and discover that one or more of the monitors have not run, it may be necessary to test drive the vehicle to set the remaining monitors.

You should talk to a good emission tec, if this is not throwing a code, it is hard to say if that one of the components could be bad. O2,pump,convert, HeO2, every part of the emission system.

With a 1000 miles, and doing what is says above just before the test, and ending driving at the test
should be plenty. If it is not, you will have to have each emission part checked, or when the computer
is plugged in it might show a code that did not trip dash light.
