My car seems to be running very lean at idle and cruising while under 2k rpms. What paramaeters would I modify to increse the fuel under those conditions?

We need a bit more info on the engine combo, what Operating System (GM or Custom EFILive), MAF or Speed Density?
Cheers,

Are you running stock exhaust?
You might have an exhaust leak. Have you done any tuning or just logging so far?

No FAST intake. I thought I had an intake leak and replaced the intake and all seals.. I do not have a WB 02 but my ltft are +15 +20 during those ranges. The seem to be fine at the higher RPM though.. I can provide some logs if anyone is intrested.

have you tried spraying starter or carb cleaning fluid around the intake? What you are describing sounds very similar to the leaky manifold problems I am having. I to have replaced every gasket several times and cannot seem to get it to seal up. Just a thought.
