I recently purchased a super charger conversion kit for my 2003 monte carlo ss 3.8 from ZZP. I bought everything according to zzp that I needed. The kit works great, I have a lot more power, but I am getting the code 0170, system too lean. The mechanic insists that it is the pcm, because he can not find any vaccum leaks, the tb is good, Maf is good, and the O2 is normal. Any suggestions? ZZP will not send a new pcm, I have had problems with them sending the wrong parts for my kit before, and I want to diagnose this before any damage occurs. Thanks for the help!

 

Did you upgrade the fuel injectors with the kit?

Perhaps you will just need to change the fuel filter.

 

yes I upgraded the injectors to GM 33#

 

Can you post a scan at all?

 

I am new to this, I just made my profile today, I dont know how to post it but I can try and put it on my profile pictures

You have to host the pictures to a website, we don't have access to your C:/ drive like you do

(try photobucket)

 

Just a suggestion...make sure all sensors around the TB are sealed good.

 

i dont know too much on this topic but, i had a buddy that turbo'd his car and he was getting the code saying system too lean. But all he needed was a high flow fuel filter. Good luch though. For sure try the fuel filter before you spend big money on other things youre not sure of.
