ok so i have a AP and i got a protune recently, all my codes are turned off that are needed too, but for some reason with the dreaded P0300 code turned off it still pops up at random times...anyone ave any ideas...??

 

Wish I had an answer. I too have been protuned and the PO300 pops up from time to time. Sometimes it just clears itself, other times I have to reflash...basically no rhyme or reason to it. For me it tends to happen when I'm cruising at highway speeds.

 

hmm same here, its weird cause i thought if the code is turned off in the AP it wont pop up anymore....wonder if cobb can pop in and give there .02

 

raiceboi697,

I'm assuming your vehicle is a 2003 Evo?

Thank you,
Rob

 

rob,

close i got a 2004. im also one of the lucky folks who get this phantom code. the only other solution i have heard is if i get a COP ignition system it will go away, but a grand for a possible solution is a bit steep.

Can you email me your map that should have the P0300 DTC disabled?

Thanks,

 

i can rob can you PM me your e mail address, sorry its taken to long to get back to you i have been driving across the US

 

Rob, any chance you could look at my tune and also turn off the PO300?

 

rob sent me some revised tunes last night, im gonna check them out and report back to see if this issue went away

 

You certainly can, but I would ask that you wait until raiceboi697 reports back.

Thanks,

 

drove the car today and the issue again popped up.... this time more freaquently then before...

 

Looks like something is amiss with the 2003-2004 misfire codes. I'll have to take a look.

Thanks guys,

 

thanks rob, hopefully we can get this figured out soon for everyone that has had this issue and not sid anything about it

 

a update to everyone, been talking with Robb @ Cobb and we are trying to work out a solution to this to help everybody.

 

Have we found a solution to this problem yet? I've been having this problem as well and my tuner guy turned off the po300 code on an accessport custom tuner map.
