This could be a really silly question, but...
Went out for a drive a while back with Brant and used his wideband air/fuel tester to get a base line on how my 76 2.0 air/fuel mixture looks. Edit: Totally Stock Djet 2.0 We were getting readings close to at about 13.3 to about 14-14.5 at cruising/load. I know that is a little lean, but my smog pump is working, so wouldn't that trick the readings, and my actual is richer than whats read at the tailpipe? Does my logic make any sense? Ferg |
