I'm sorry, let me restate the issue. Once I let off the gas it temporarily spikes lean for no more than a second or so. During idle, it will bounce into and out of lean.

As for my injector fuel rate: the stock injectors were 22# (right for an L36?) at an 367 flow rate, the Siemans Deka injectors are rated at 65# per the ZZP site. My math was 22/65=.3385, 367*.3385=124.23

Isn't that correct?
