Check Engine Light Problem
 
I installed a Steeda throttle body spacer a couple of months ago. Now about every 2 weeks give or take I get a P0171 code (System Too Lean Bank 1). Everything is tight and installed the way it is suppose to be. Anyone have any ideas? It is tuned by FSWerks I wonder if that makes a difference?

Moved to "General Technical Chat". It could be a vacuum leak or your first o2 sensor has gone bad. You might want to see if removing the TB spacer will help.

vacuum leak would be a very likely thing to check for.

Have to agree with a Vac leak , take the spacer off it doesnt help and as you can see is more trouble then its worth

You list a xcal3 use it to datalog and see what the problem is , if you want to email me a datalog I dont charge to look them over and tell you what I see wrong

We can take a look at it on Saturday if you want.

There is no vacuum leak already check for that. I don't think the O2 is bad since this only happened once I put the spacer on. I think I will just take it off and see what happens.

I could datalog it but that is kind of pain to deal with.
