Got my main fuel issue fixed (FD), car running pretty great now good idle, power and cold start. Do though, have an odd (quiet) popping thru exhaust only when... I'm in a lower gear and decelerating from up above 3000 or so RPM. Sounds like a lean miss on a motorcycle. Cap/rotor/wires/plugs have very few miles on them, wires are NGK cap rotor is german beru I think, plugs are "r" but have correct ones on the way. Not aware of any exhaust leaks but I guess it's possible, but didn't show up before this work was done. I'd think maybe my EHA (not leaking) needs a tweak but the thing is, it seems intermittent. Ignition parts? Thanks
