2187.

Discuss.

ur throwing a 2187 too lean at idle code

The fix?

Nothing? Your running the Cobb SRI I wouldn't worry about it. Just clear it and your fine if it keeps poppin up then i'd worry.

We reset it today, but it tripped again.

fucking weird... Um.... I'm not sure... email christian at cobb? Should be christian@cobbtuning.com or tech@cobbtuning.com

also make sure everythigns tight maybe remove the intake and disassemble and reassemble to make sure its all good

OK, thanks for the input. I'll have a gander tomorrow.

I think, but cant remember correctly that this problem/code is covered by a recent TSB.... i just cant remember.

TSB?

Technical Service Bulletin. Issued by Mazda North America. Its kind of like a recall but instead of a full blow recall, they are problems recognized by Mazda and are brought to the attention of dealers, so if a customer comes in with a said problem covered in a certain TSB, the dealer will know how to take care of it.

andrew, you are right, the P2177 and P2187 are both related to the recent TSB on the fuel pumps. Let Mazda know whats going on, they will put the pump through a series of tests, and determine if you are eligible for the new fuel pump..

Word up G!

Shane, found this info on another foum too:


Hi all,

The CEL was on last week and dealer told me they replaced "Purge Solenoid Valve" for the error code p0171/p0172/p0441/p0442/p0455/p0456/p2178/p2187/p2188. And now my car is running fine.

Awesome sauce. I'll call them shortly.
