1999 Toyota 4Runner Q&A
1999 Toyota 4Runner Question: My question is where do I get the conversion tables mentioned in the article?
In the article about "Fuel Syatem Too Rich" there is a section on determining if the MAF is faulty. Part way down the paragraph, the statement is made.... (These conversion tables will help.) The conversion table are for calculating Barometric Pressure for elevation. Where do I find these conversion tables? I need to evaluate the parameters of my MAF to see if it is faulty because I keep getting a P0171, Too lean code and I can not find any vacuum leaks. Thank you - DRMILLAN
WHILE MAF CAN CAUSE THIS, SO CAN A LOT MORE STUFF. MAP SENSOR,FUEL PRESSURE LOW, PCV VALVE, 02 SENSOR,INJECTOR(S) AS YOU MENTIONED VACUUM LEAK. DO YOU HAVE A SCAN TOOL THAT CAN STREAM LIVE DATA? AS FOR BARO. PRESS. READING CHECK THE WEATHER CHANEL, TYPE IN YOUR LOCATION. - pushrod
