p2187 is back after a purge valve change

[gskills]

So I got the p2187 code a few weeks ago... after some reasearching i was told it was most likley the purge valve... well it came back a week after the purge valve was changed .... what else could it be ?

any mazda techs? any thoughts ....

I just picked up a knock off gas cap (Stant) for 20 bucks new...


can a gas cap throw that code.....
anyone....

A faulty gas cap can throw a code. I'm not sure what kind of code it would throw though.

how about the MAF ????
Im taken shots in the dark here

if so can I clean it with this this throttle body cleaner i used to clean my throttle last year when it was caked with carbon ect....

could be the maf or its wiring
check for vacuum leaks too

ok so i just picked up a bottle of gunk maf cleaner, just took it off and im going to give it a spray.....


I also stuck my head in the engine with the engine cover off and lising for a leak and i could not hear one... but What do I know....

I checked the connections on the purge valve and of the blue tubes beside it. I made sure my airbox and such was tight to the throttle body and Im going to tighten my throttle body as well *i had that off last year to clean up all the carbon that gave me a rough idle*

What I know so far
-I dont have a rough idle
-never had problems starting on emtpy or full
- the gas mileage seems to be ok ( im going to document it now)
-Im also making a car log of how many times I stop and start - warm/cold and how many times I crack the gas cap....

what a pain in the ass

Why don't you just take it to Jimmy and see what he thinks?

Since purge valve was replaced and still same issue it sounds like an oxygen sensor. I'm sure Jimmy will tell you the same thing.

I wish i could take it to Jimmy but Im a few provinces away :)



It was a nice day today, I took my cover off and stuck my head in the engine bay and I could not see/hear a air leak. I used a tiny wd 40 bottle and sprayed around the intake and various pipes seeing if the engine would bog down or see stuff get sucked in... nothing

I cleaned the MAF with the right cleaner - it was pretty clean I also re-cleaned throttle body (it was getting dirty after only 15,000km)
I also checked the gasket on the throttle body but i could not see anything...

what a pain in the ass ill feel better once i put another few tanks of gas in the car and dont get that code...

on a side note the 2 screws that hold the MAF in place one of them just spins and does not seem to make a great seal. the other one is nice and snug....
Can I use a slightly larger screw, they look like wood screws to begin with ....

[TheMAN]

sounds like you found your problem
you can try to use a bigger screw, but if it were me, I'd just fill the screw hole with glue, let dry, then put the screw back in

[gskills]

ok i was about 2 mins away from putting a slightly larger screw in....

Ill try the glue idea first... but what kind of glue ? super glue ? Will I be able to take out the maf if I have a problem agian.....

thanks

[gskills]

bah i just used a slighty larger screw and it is super snug now..

i hope that screw was causing the 2187 but who knows
