CEL and surgeing

I have a H/C all the bolt ons 00 T/A The cam is a comp XER281HR The car surges at idle occasionally and throws a lean code on bank one. PCM was done by pcm4less. Haven't been able to find any vacuum leaks.

Probably need a better tune. Can you scan the oxygen sensor to see if its working properly?

When I got the scanner hooked up it was @ operating temp and working properly, but it may be lazy from a cold start.

What about header/exhaust leaks? Do you have clamps or is the setup welded? When was the last time you checked the drivers side (Bank 1) header bolts? Something on the driver's side. If the problem tends to be in one bank then I would look at the exhaust system before I focused too heavily on the tune.
