What's and MAF?... either way..had them both changed and car runs like a charm so far.....do the same, it's a common problem with these cars and toyota carolla.....hope ypu get it fixed. Good luck

Thanx for the feedback...did you get both of them fixed? and had the light gone back on?

hey...i'm no expert but.. my wife drives a suzuki..and she had the same problem...it so happens that there was rust inside where the brakes go(shoes) AND WHEN TURNING WITH ADDED PRESSURE FROM AN INCLINE it would scrape with another metal...i am not mechanically inclines but it sure does sound familiar.

there are two knock sensors, one for each bank. it might be the other one thats causing the light to come on. also you shoould have him check the harness that comes off the sensors, it gets connected to the main engine hearness around the thermostat housing area, just to be sure. Again this is based on the fact the engine is not knocking of course.. good luck Thanx so much for your feedback! i appreciate it! :D

Hello...i recently purchased a 2000 lexus rx300 with 84,000 km(not miles). Car was running great when i test drove it. However, after 4 days, the engine light came on. Immediately i noticed that the car lagged behind and would rev much higher to move than it did before. I got it checked out, and it ends up that the knock sensor was down. The certified Lexus mechanic told me to disconnect the battery for 2 seconds and see if the engine light turns off, and it did! The car was running back to normal.( no lagging or high reving) However, the day after the light came back on. Immediately i took the car back to the mechanic and he changed one of the knock sensors for about $500.00. Car ran great for two days and then engine light came back on. Got it checked and shows the knock sensor again. I don't know what to do now. Has anyone experienced this before and have any suggestions, please help! I'm also only getting about 390 km on a full tank because it is reving high. Thanking you in advance to anyone who can help.
