The first generation of the Lexus RX300 luxury sedan SUV crossover.

My 1999 rx300 takes alot to start and loses power

Very hard to get started and loses acceleration fairly often while driving . It's intermittent but then after feathering the peddling gas it comes back. What is the cause of this?

Have you scanned the car for any trouble codes? When I had a similar issue on my '99 VW New Beetle, it turned out to be a failing MAF, or Mass Air Flow meter. An OBD-II scan showed a code for that issue and replacing it fixed the problem.

Yes codes say bank one too lean . And something about bank 2 ac sensor. Idk what they are . Have new plugs and wires , new mass air flow sensor, new 02 sensor . Still having issues not sure what else to do from here.

@davidreza24695 Can you give us the specific codes you retrieved? That may help pin down what's going on.
