RE: [DML] Anyone able to contact PJ Grady?

Hi Mike,


I haven't been avoiding you but I am extremely busy and can't easily answer
that question. The short answer is there is no one answer! There are many
different conditions or causes that could create idle fluctuation (vacuum
leaks, timing, CO adjustments, idle circuit issues, rich or lean fuel
mixture, bad gas, etc). Has anybody worked on the engine recently? You need
to have a good mechanic look at the engine and check all the basic settings
(Timing, vacuum hose routing, CO adjustment, emissions, fuel pressures, idle
and lambda circuit functions, etc). The answer lies in one of these areas
but which one is anybodies guess. Only God could nail it in an e-mail
without inspecting the car firsthand and I haven't been able to reach him
lately either ;-)


Rob Grady,
