Hey, my car has been idling lean for a few days, we're talking like 17.0-18.0 AFR.
the code p0455 keeps coming up, which is a leak in the evap system.

The DIC told me to "check gas cap"
i got a new cap, and that didnt work.

not too long ago, i noticed the evap purge solenoid ticking kinda loudly... could this have died on me?

anyways...whats the part number on the evap purge solenoid?
any other common places i should check for leaks?

thanks

 

is it a constant 17-18afr or does it missfire and sit there for a while then correct itself?

 

constant with misfires too
haha

enough to throw a p0300

 

p0300 its not that big i have gotten it sometimes and my friend. he says its because of the 60lb injectots. now the being lean yea not cool

 

does anyone know?
help please
thanks

 

hm did you check your brake booster line, and your blow off line, actually all the vacuum lines and my hahn manifold the holes were a little loose around the two sensors, i had to get new gaskets for em to seal correctly...

sounds like a big leak

 

evap purge only works while at cruise so you can rule that out

 

thanks guys.
ill check all that hungry.
i noticed some of mine were a little loose too...

 

Im throwing a P0300 code after the install of the Hahn Stage V kit. Car idles like crap and I also am noticing a loud ticking from the evap hose and the module where the evap hose connects to if you feel it you can feel the clicking very loud. Anyone know anything about this??

PS. 60lb injectors by the way

 

the ticking is coming from either your injectors or your one way check ball in the pcv. they both make a loud clicking noise this is normal...

 

hey guys, i just seafoamed the car and it is running a little better, but it is still idling at 16.5-18+ afr.
i have checked all sensors on the intake mani, and all the hoses i could see, and used the propane method for checking for leaks.

hungry, does your hahn intake mani squeak or squeal?
Bryan (06black) says its because its sheet-metal and something in it resonates.

anyways, does anyone have any ideas?
i have my new plugs in it, gapped to .030 and its still misfiring like a **** at idle to.

thanks

 

update: it actually seems to be just cylinder 1 a great deal of the time
ideas?

 

Misfires at idle is normal with 60# injectors. Aside from that I can't really help as I've never looked at a turbo swap balt.

 

yeah i know, but it has never ever been this bad at all.
the extreme misfiring came with the lean idle...

 

bad injector in that hole?

have you done a compression test or leakdown test?

 

bout to run a compression.
gonna check the injector buckets and orings too.

 

Clean your MAF too if you're throwing a lean code. You may also need a retune.
