Thanks I'll give it a try. I changed the gas cap and check the hoses around the airbox. I did't notice any hoses disconnected. The code #'s are P0125, P01130 and P01135. I am going to try and check the hoses again and see if I see anyting.

Thanks I'll give it a try.

We had the check engine light come on on my wifes 99 rx. MPG started to drop and it will idle rough sometimes. She took it to the Toyota dealer and was told we need to replace the "mass air flow meter and a/f sensor" for $621.50. I first tried to clean the MAF. The light came back on. Next I replaced the MAF with one from Advance Auto and same thing the light came back on after 10 miles. She had Advance scan the car and it showed 3 different readings. 1. closed loop fuel control 2. insufficant coolant temp 3. fuel air meter I am at a lost on these 3 readings. any help would be greatly appreciated. Thanks Jake
