Question MAF Sensor Problem

Ok my check engine light came on and it was throwing the 34 code which means my mass airflow sensor is bad.. ok so i go buy a new one and pop it in and then still the light comes back on after about 5mins of driving... also i think because of this my rpms drop to about 500 almost everytime i slow down to a stop and kinda bogs a lil when taking off when the car hasnt warmed up yet. anyone have any ideas?? should i try getting another one??? its under warranty

This question should be under FAQ's if you read any of the posts other than the ones on the first page you would see this question about 8 times maybe more. If you look back by the brake booster on the firewall you will see two relays that look like all of the other ones undre the hood. Go down to the auto store and buy two of them (should be around $20) and replace them ,reset your light,should be all better.

Go to www.thirdgen.org and do a search on Maf sensor relays.
Some good pictures showing location and what they look like.
A little effort but pictures are worth a thousand words.
