So for a while now my car has been running like crap which I associated with bad cats. I always get the rotten egg smell when going up hills or accelarating hard plus the extreme loss of power. So I ordered QTP headers/ORY to get rid of the silly cats (if they ever come damn back order crap). The problem now is that code P0171 started to pop today which is "System running lean(bank 1)", and this is a couple days after I put in a new granatelli MAF. So my question is what should I do now? I already put the stock MAF back in and cleared the code to see if it would pop again..... and nothing yet. My main question is once I get the headers/ory and maf all in should i chance driving the thing if its going to be running lean (I was planning on getting it tuned right after), or should i get a tune now with the MAF only and then get it retuned after the headers/ory go in? I really don't want to mess the engine up because thats more money then I wish to spend at the moment
