wait a minute. YOU DO NOT CLEAN THE MAF. everytime i hear someone say they cleaned the maf it is followed by 'my car wont start'. you will probably need to replace the sensor. the lexus upgrade is possible because it uses the same electronics, but it is 25% larger, allowing 25% more air. to balance the fuel mixture, larger injectors are used, specificly 550's because they are 25% larger then the stock 440's. replace the sensor and your car should be fine, or get the lexus maf, 550's and a wideband gauge to moniter your a/f's.
