I know, I know, no CEL...

But it almost sounds as if the ECM has put the car into some type of limp mode.



Have you tried resetting the ECU or disconnecting the battery for 30 minutes?

Another W.A.G. from a 4 cyl guy:


Modern computer-controlled engines can be sensitive to a "clean" ground. (In fact, some auxiliary "earthing kits" are sold as performance enhancers.)

Have you verified a low resistance back to battery negative? Did Lotus still use a solitary earth braid from the RH motor mount on the V8s?

That's a great thought Atwell; even if Knut's problem is different; low, or unstable power to the ECU certainly could manifest in odd ways. Wonder what the current draw is on the ECU and how is it grounded.
:clap:

Actually, the theory is that good, clean ground paths provides stable and accurate readings from the various sensors, to the ECU.

Otherwise, it's GIGO. (Garbage In, Garbage Out) :shrug:

Wow, I'm used to the metal "honeycomb" type of catalytic matrix. I didn't know Hi Flow Cats used a "Swiffer" to clean the exhaust... :huh: :scratchhead:


Seriously, is that stuff as soft as it looks? If so, NO WONDER it moved around...
