Yes the airflow meter is very easy, it is in the air intake hose to the engine from the air cleaner. Boy those Japanese car makers really take you to the cleaners on repairs, that repair on a GM car would have been 1/2 that amount.

chances are you don't have to replace the computer. the reason i tell you this is because you did not mention that the car is running lousy. no complaints of rough idle or missfire or hard starting. chances are that your engine speed sensor which sends the signal to the computer which then controls the transmission is most likely the culprit.. and it could just bhe that there is a loose connection between the two. if that is ok then your transmission control module is faulty. this is not the main computer, but the gobetween the trans and the ecm.. hope this helps please rate this...thanks(btw....the knock sensors control timing not the trans mission)
SOURCE: knock sensor
knock sensors are underneath the lower intake. replace the knock sensor harness as well

You replaced the wrong sensor. Here is a link that can further explain how to trouble shoot this problem http://us.lexusownersclub.com/forums/lofiversion/index.php/t14194.html
Check for Vacuum hose for leak,crack or blocked first then, Vacuum switch Valves for vapor pressure sensor next to the Evaporator Charcoal Canister rear of the fuel tank. Charcoal Canister crack or damage. But mostly likely Charcoal Canister and vapor pressure sensor replacment. Tell us the result.

Took the car to the dealership. $116.20 later after a computer system check. I have a knock sensor that is bad as well as a air flow meter problem. Knock sensor repair (cheapest pricing) was $684.91 for parts and labor. The air flow meter......my husband thinks he can fix so maybe just the price of the part.
