Default 99 ssei dtc P1676?

hi i have a dtc that i cant figure out the cause of it
i clear it and it takes about 75 miles for it to return
i have a zzp pcm with evap delete and rear o2 delete

i tryed swapping the purge solenoid no luck
also this happened right after i put my magnaflow cat on

what i dont get is that a driver 4 line 6 is in regards to a evap code?

zzp was supposed to delete those?

Email ZZP and ask them. We can't troubleshoot what'* not supposed to be there very well.

First off, please list the code description any time you list a trouble code. This ensures if you mistyped.. that the description is right.

Theft for fuel cutoff signal issue? That'* the code?

Gamover, I don't know where you got that from, but we need the code DESCRIPTION. I've never heard anything like that before. Sounds like you have some funky scantool.

Wow..how the heck did my tired eyes miss that.. (I actually looked BTW)

This is probably a flow when no flow is expected condition. Check all lines going to the evap soleniod behind the SC. Also check the connector.

I recently had one die after 170,000 good miles.. I replaced with a JY unit ... any 96+ will work.

But he stated ZZP deleted the Evap code from the PCM.

This is a ZZP PCM issue, not a troubleshooting game.

Ahhh correct a mundo (for once at least...lol)

Seems like they missed the boat on part of the PCM reprogram. You might want to check your receipt to ensure it was deleted.
