P0171 Lean 1
P0174 Lean 2

I noticed or it seemed to happen at idle or moving very very slowly (i sit in traffic to/from work)

It happened last week sometime (actually this last weekend) and again last night.

I plugged in the x2 while driving home in traffic and reset them on the fly and then tossed the x2 on the seat and continued home.

I tried to tap off all the wire on my TB this last weekend for hte nitrous TPS switch but thats been disconnected and all wires wrapped in electrical tape. Don't know if that had anything to do with it.

I flashed the nitrous tune in my car and then in the morning (sunday) put it back to my 91 octane tune from Doug.

Car runs fine with these codes and doens't go into limp mode.

Doesnt worry me too much but i do have some concern considering i'm about to finish my nitrous install once i get some help from a guy local to me.

Any ideas or suggestions?

thanks,
jake

You know something... I think the vacume tube on my intake is loose and If i remember correctly I needed to tighten it one day.. It's probably the culprit.

i'll check.. but thanks freebass55, this helps a lot !!!!
