I was doing some aggressive driving then I noticed the check engine light came on , read the code with the accessport , says purge evap valve emissions , anyone ran into this code before and what should be my next move ?
Clear it with your AP.
See if it comes back. That is one of those codes that appears, and never to be seen again.
While you are there, do a KAM reset. Actually that is good to do on occasion.
Ok cleared the code started up just fine , went back to reset the KAM and when I started it up it stuttered a little bit then started up , is that normal . . ?
Yes. It hiccups a bit. What you are doing is clearing the keep alive memory.
So if you drive like a granny, it learns granny driving.
Clearing it every once in a while keeps it more "alive"
In the Helm manual it says it will run a little rough when you first start it after a KAM reset. It says something about letting it idle with the AC on for a couple minutes before driving.
You don't need to retune after a KAM. See if you can notice a difference after a reset.
Ill bet you feel a much sharper throttle response.
Let us know if the code returns......
Had a P144A-EVAP Emission System Purge Vapor Line restricted or blocked.
Came about after piking the car up from the dealer the day before for my second AC repair. They did replace a part if it mattered. I'm on the stock tune, never been tuned.
Exhaust issues so soon could mean another underlying issue. Like too much gas is escaping into the exhaust and igniting after it leaves the engine because you are running too rich or the spark is not hot enough to ignite the fuel.
Well I did just replace the spark plugs about 2 weeks ago , not sure what could be wrong with the exhaust , I have Borla ATAK Catbacks installed . . haven't had any issues until I replaced the plugs just recently
Check to make sure the harness is fully plugged in on the purge valve. The purge valve is the little canister on top of the intake manifold on the driver's side. It's about dead center on the manifold there, with a little metal bracket holding it up off the intake manifold. There's a harness jumping to it from the spark plug portion of the harness. It may have come disconnected at some point during your installation of the spark plugs, as you're working in that area a considerable amount when swapping them.
Also, make sure that the line coming off of that valve (and going into the top of the throttle body) is plugged all the way in and the little red clip is holding it into place.
