I bought my 1999 Rx300 in March 06, it had 86 K on it for $14000. It now has 106K. it has been problem free until now. I have the check engine light on, code P1135, i believe it is air flow sensor, cost is $170 for the part, my friend will instal it for free. He says that it doesnt effect your car except for emission. But no harm to the engine.
I havent done any work to it. when i first bought it the transmission fluid wasvery dark so i had them change it for free (nissan dealership in middlebury, CT). My friend installed a radiator for the transmission, cost was $40 for parts, labor free. Since then the transmission fluid is still pink and clean...
Any idea of the best way to solve code P1135 ? Does the air flow sensor before the car impact the engine ?
Thank you for all your help, it is greatly appreciated.
