Guys I need your urgent assistance in resolving the issues with my Mazda millennia 2002. especially the p0505 error which is the IAC/PCM error.

 

you should go to the other site, mazdaworld.org. you will have to register, then go to the millenia section. look for yel-low, he is the resident transmission expert. the 3 digit codes are transmission codes. also, you will need to post which engine you have, 2.5 or 2.3, and what the car is doing. most of the time, if the trans is a problem, you also get tcs off/tcs lites on the dash. yel-low is also one of the 2.5 experts.

 

Thanks @keninn
