I have been getting the lean codes for Bank 1 and Bank 2. I clean and replaced MAF. I had previously replaced the famous vacuum elbow (and it's still good). I have had a smoke test done to find any other vacuum leaks. A small amount of smoke came from the EGR, replaced it.
The codes have come back yet again.
I would like to add that the engine occasionally has a bit of problem. When I start it, it may fire up fine, or may want to drop out briefly (or even die). Idle can be mildly rough anytime. I "think" that part may be a fuel delivery issue as it starts via remote (which turns ignition on for a couple seconds before crank), and if I do the same manually, I do not usually have the start issue (but still can have the idle issue). I have recently put injector cleaner in but may not have driven enough yet.
Please let me know what else it may be. I could ask for another smoke test but the EGR was the only leak found.
Thanks for any help.
