I've been lurking around here for awhile trying to self diagnose a CEL and trac off prob... It gives code of P0171 Bank one lean, I started with cleaning the MAS with TB cleaner and drying it out..Disconnecting battery for 15 mins to clear CEL.. Car has no power at first but will start to regain its old self after a few miles... I think this is the result of the MAS being cleaned.. The CEL and trac light came on again.. Does this mean that the MAS is garbage get a new one since cleaning it didnt fix it? and to buy a new one for $250 ish? If so what is a good internet store for them? How do I discern that it is the MAS and not one of the three O2 sensors? I looked around the bay for loose hoses for a vac. leak but I really dont think that is the prob Should I buy a new MAF and hope that fixes it or should I go the O2 route first and replace those? Thanks for the input 99 RX300 126000 miles 2wd Transmission strong as ever :) B

My 99 Rx Passenger front door doesnt register when it is opened. Lights do not come on, nor does the door open icon on the dash register. Where is the switch (usually located on the door frame, or door) located? Any one else ever hear of this Begvis

How difficult is it to do a oil change on a 99 Rx. I just bought the car and heard some difficulties in removing the filter. I wont have jack stands/ramps, but can prolly get a foot of clearance under the car. Also, Mobil 1 syn will be the oil, got a filter sug? thx in advance beg
