I installed the pulley 2 days ago and now have codes P0300 (random misfire) and a U0073 (CAN communication error) I tried to reset the KAM and VNRAM and these codes come back.

I don't want to remove the pulley because there are no signs of performance loss as this CEL only comes on at WOT after 6K.

As for a quick review of the pulley....VERY worth the money. The power in the mid rpms is def. more noticable. By far the best bang for the buck (minus the current CEL ) Also, this was mentioned on the boards before and believe it or not the exhaust sounds a bit different (a tad louder) with this pulley. I can't explain why though.

Any ideas with the CEL?? Thanks

 

Did you somehow remove or move that toothed crank positioning ring thingy that was right behind the pulley? That is the only thing I can think of that may cause your problems. Someone posted about a similar problem after installing the agency pulley about a week or so ago so if you do a search you may find the solution. I would provide the link but I suck at that kind of stuff.

thanks for the link staticlag. i've done that (20 brake presses in 8 seconds KAM reset) and for some reason the CEL doesn't turn off when I start the car. I see the oil needle sweep half way and back and then start the car right?? I went ahead and put the stock pulley back on and manually cleared the codes with my scan tool, but they came back just as before.

 

I ended up just unplugging the battery and putting the AP pulley back on to see if that would do the trick. sure enough the CEL hasn't come back after my test drive Is it normal my car doesn't respond to the KAM reset??

 

yes i have found also that to clear the kam you have to remove the batt cable... i have done this a couple of times to reset the ltft..

beers

 

Just installed AP pulley and performed the > 20 pedal stomp in 8 seconds. The oil pressure gauge did its sweep, but still have the flashing CEL on WOT > 6000 RPMs. I too will try the unplugging of the battery and depress brake pedal to reset the eccentric shaft profile.

Laters!

you have to clear the ECU memory, those in-car tricks won't do the complete trick

 

When I put my agency pulley on I got the same CEL as well,
all I did was used the brake tapping to reset. stayed on for a few days then
suddenly went away. I figured as it's learning ecu it'd juz get used to it
could be wrong,

 

Good read! just installed my AP Pulley tonight and that dam cell came on. I pulled over pulled out my Scangauge2 hit delete but it keeps coming back gerrr. Guess I'm going to unplugging my battery too. How long should I let it sit for?
Thanks!

 

Don't have to do it this long, but give it 15 minutes.

 

^Thanks man!

 

What have you guys felt with the new pulley? Any difference in power?

 

I honestly didn't feel a difference.

 

^^^Interesting.

 

I don't have the Agency, but rather the Unorthodox set and to be honest, probably only felt like there was a change for the better in throttle response. It was noticeable though.

 

Yup same here. Car moves after 5k rpms WOT! I love it. But hate that dam cell gerrr
