Hi everybody on the forum, sorry it took so long to respond back with a problem I had with codes PO171 & 174. The info you guys shared was great but, it didn't solve my problem. I ended up digging deeper, to make a long story short I when back to square one, I went to the Halltech website & there was some problems with the old halltech stingers with the so mention codes and I call them & come to find mone after talking to Jim Hall @ Halltech the MAF sensor didnt come with the honeycombe inlet on the frt of the MAF & it was flowing too much air causing it to run lean.
Jim ended sending me the honeycombe insert to add to the MAF sensor so far no more check engine light or PO171 or 174 guys if ur having a problem with those codes contact Jim Hall @ Halltech.
Also I'm getting better gas mileage & cooler engine temps.
Thnx,
