Very good information, only one question though, my truck will only run rough and misfire while throwing the P0103 code only after driving in rain or wet conditions. Any suggestions would help!

[@HVAC_Mechanic]

It will need to be diagnosed, but if it happens when wet, there is likely an exposed wire somewhere, or the intake is open, letting moisture in.

Thanks for the info. Experiencing this issue. Cleaned the MAF as recommended. Still shows the code, car stalls and hesitates. It's a 1996 volvo 850. Has 170,000 miles but well maintained. I'm looking at replacing the MAF but I see them range from $ 34 to $ 250 in price. Don't want to go cheap nor over pay...suggestions?

I also have a Volvo 850, but mine is 1995 instead of 1996, I would say if you're looking for parts I typically stick with FCP Euro or IPD. Their aftermarket parts are trusted and usually ship within 1-2 weeks depending if they have them in stock. I don't think you need to pay $250 for a MAF sensor, the one I bought was right in the middle around $150.

My Lexus died, just won’t start. I started with the battery, put a new one in, still won’t turn over. It read this code, so I bought the cleaner and cleaned it, still won’t start. Any advice?

Maybe you need a new ECM.

Very cheap to make a smoke machine or buy one.I have solved many of these problems with smoke.BMWs to Toyota Tacomas.
