Folks —
I have a 2005 Elise with ~34,700 miles on it that I recently purchased from an LT member (first owner) who bought it from, and had it serviced religiously by, Lotus of Atlanta.
I am concerned that the second cam may not be functioning properly. The reason for my concern is that (after the engine is nicely warmed up) as I accelerate past 6,000RPM and on toward 7,000RPM, the power seems nice and strong, but with no real “kick” as I get up to ~6,500RPM or so. When I drove another Elise a few months ago (prior to buying mine), I noticed a strong “kick” as I passed ~6,000 - 6,500 or so, kind of like the mechanical secondaries of a 4bbl carb opening up.
In reading through the archives, I saw a post that seemed to say that if I could rev beyond ~6,200RPM then the second cam was working. Is this correct?
As to symptoms, I have not noticed any strange noises and the MIL is off, so I am not sure that I have a problem (the MIL worked fine when I had it smog checked a couple of months ago). The PPI was performed (including checking the cams) by Lotus of Atlanta at ~31,600 miles (April) and it passed with flying colors.
Thoughts, suggestions?
Thanks!
