You have to be desperate to go to all the effort of removing the dash to replace it with that garbage.

Lean codes are mostly vacuum leaks on these engines so you need to start with a pressurized smoke test, waste of time imo trying to find leaks without one. You can DIY one easy enough with hardware store etc parts and most people have an air compressor. Test is pretty simple - Remove airbox and ducting, remove the MAF and install a airtight zip lock bag etc on the front on it and re-install it. You can then either remove the F connector from the intake boot in front of the maf and pump smoke in there, or you can use the rubber capped intake ports at the back of the intake manifold (which can leak). This requires removing the cabin filter, housing and side of the ecu box which is straight forward but gives you even more room to see any possible smoke.
