OK,
Guys. Here's another chance for your valued remote diagnosis
input.
After
2 months hiatus my engine now starts reliably and runs
consistently....just very very badly. In all the time
I've had the engine running, with various problems of mixture and
tuning it has NEVER run this rough. It shakes, and max rpm is about 2100.
Each plug seems to have a good spark but today I installed new plugs anyway and
checked the voltage on all coils and injectors. It runs exactly the same as it
did yesterday. The plugs are black and the engine blows a bit of blue
smoke.
It IS
running rich, so I tried changing the overall range with mode 3. As I lowered
the mixture with 7 or 8 pushes the rpm came up a bit, then started to slow down
again. At the best rpm the EC2 is showing slightly higher than center on the
mixture. I tried switching off either set of coils and felt a degradation with
either off. Disabling secondary injectors killed the engine. Primaries
didn't make much difference. I checked compression. 105# on each
rotor.
My
next thought is to check that cold start is operating properly, but I'm pretty
sure it is because the engine slowed down when I tried switching it on.
I spoke with Tracy and he suspects fuel, possibly a bad
connection in the injector wiring, so tomorrow I'll rewire the entire injector
circuit if necessary.
I'm so glad Rusty still doesn't have power. I'm not in any
mood for jokes :(
Thoughts anyone???
