Hi guys,
I'm currently fighting a very lean idle on my 5.3 swapped vehicle. The current setup is as follows:
2003 (I think) 5.3 out of a Silverado 1500 DBW
Stock GM truck MAF
Stock GM truck DBW throttle body
Stock 5.3 truck injectors
2000 LS1 intake manifold
228/230 .585 .585 112lsa camshaft
PAC1218 valve springs
Long tube headers
TH350
3000rpm stall
It has new o2 sensors, and new plugs. The LTFTs are pegged, although bank 2 sometimes falls back down, only to rise again. The plugs show a very lean condition.
The vehicle has been swapped and running for about 4 years now, but this spring I did the cam swap. The current tune is a mail order deal. I went that route before I decided to pick up Hp Tuners. Is there anything that stands out to you guys in the tune or log? Hopefully they post, it's my first time uploading something like this.
This post is in no way blaming the tuner. If anything I probably screwed something up and I'm just overlooking it, but I figured another set of eyes on whats going on could help me.
Thank you guys!
