My 09 Mazda 3 got a code it was p2188

Good Afternoon, my name is \*\*\*\*\* \*\*\*\*\* ill be helping you. so sorry to hear about the issues here on the Mazda. Can i please have your VIN?

thank you, \*\*\*\*\* \*\*\*\*\* moment

this code indicates that you are running lean at idle. not rich. running lean would be caused by several issues but the most common is vacuum leaks. you would need to verify that there are no vacuum leaks, that fuel pressure is within spec and that the MAF is reading correctly since any of those 3 could cause a lean condition at idle.

how would I know if the is a vacuum leak

if theyre especially bad you can see or hear them, if nothing is obvious visually then you will need a smoke machine to narrow it down.

i know my Mazda as a probably with the evaporative emissions evap would that have anything to do with it

it could leak vacuum from there but its unlikely without any EVAP codes setting. we would still need to do a smoke test to pinpoint the vacuum leak

I have had evap codes on the car

ah okay good then its a possibility but we still need to do that smoke test to be sure.

I have took it to a shop more then once and was told it was find the code I got today said it was to Rich and I did put some fuel injector cleaner in it not to long ago

ah okay. no the code you have is for running lean off idle like i mentioned

I don't get it it was code p2188

if you want to rule out a rich at idle verify that your fuel injectors are not leaking or you have an issue with fuel pressure being higher than normal. you can also check for vacuum leaks after the fact like i described. get that done and let me know what we find out, thank you!
