Well, you have already changed them, but you may have a circuit issue.

Do you have access to anyone with a diagnostics tool? 2nd best would be a mutlimeter if you can get a hold of one.

And first, can you pull the codes and list the actual code numbers you are seeing?

 

just for ha-ha's, check the o ring on ur maf sensor and make 100% sure that its seated correctly. if it happened to roll, kink, or become fubar in anyway, it would throw your readings off. and yes it will throw the p0172 rich code. i had this happen to me and it was driving nuts. if u cant tell right off the bat, spray some brake clean directly on the maf sensor and listen carefully for any changes in idle. if u hear it drop, than ull know right away that something isnt seated correctly. fyi, dont spray heavy with the brake clean, do lil 2 sec bursts.

 

Alright I have a mutlimeter now what? Also I got the code it is "p0172 system running rich bank 1"

 

ok I'll try that thanks.

 

did you reset the ecu after changing sensors? not just clearing the codes, i mean disconnecting the battery for 30 min.

 

Yea tried that.
