well, the wifes' 4runner threw a 0171 code.
i had the same problem in my 99 es300 a while back and i had the maf sensor replaced and solved the problem.

so i used my maf in her truck and no problems. so i need to see if the part # in my car is the same as hers

i searched and couldnt find it. i was also wondering if a cardone one from autozone/advanced auto would be an acceptable substitute instead of the toyota one, esp at 30-$50 cheaper

thanks

 

for anything i like that i wouldnt trust aftermarket brands, oem rocks.

theres plenty on ebay, search for "4runner maf"

 

Try cleaning it with brake cleaner and reset the ECU by pulling the neg batt terminal.
If it comes back again, then replace.

 

i did clean it and the light came back on. she was having problems accelerating heavily and it felt like it was lagging. she still has my maf in her truck and no problems.

i have hers in my es300. i was calling a few dealers for the part. i was quoted 168-185. but we also have quite a few salvage yards in the area and can prob get one for like $30 or so, but if i had the part # i could search the part # on teh net

 

call the yota dealership

 

Brand new on eBay:

i did see that this morning, not new, but most def cheaper than new.

oh yeah i did have a k&n filter in there. i replaced it this weekend with a purolator one to solve that problem.

there is a pretty decent recycled parts place nearby, so i will check with them too

 

You're right, I stand corrected.
