MCU?
Have a 88 yj with 4.2, standard.. Rins roughon cold start and excessive
crank on hot start. Dealer service says metering pins are not moving in and
out to regulate air and fuel.. Says the mechanic metered the MCU and it is
faulty. New part is $800.
Are they on the right track or are they trying to pull one?
Trying to get ready for the ontario E-Test. Will it pass the e-test with
out replacement?

New? It probably just needs rebuilt.
Dealers charge way too much. $800 is a pure ripoff.
For example, the rebuild kit for a 72-90 Weber Carb (which I think is the one in your jeep) Please make sure before you buy any
rebuild kit.
A full rebuilt carb from Napa is only $324
An OEM carb from chryslerpartsdirect.com is $251.10
The Factory overhaul kit is #30.38
Any decent mechanic can do the work for you and probably for $100 + parts.

And actually with the current exchange rate those prices will be better.
(I priced US$)
As for passing the e-test up in Ontario.. I don't have a clue. Might get
by with some carb cleaner.

MCU = Microprocessor Control Unit. He's talking computer, not carb.

doh.
I got stuck on pins and fuel/air.
Isn't that the carb they do the nutter bypass on?
Either way, the ECM is US$294
And I still wonder if the metering pins are not a part of the cause
as they can also stick.

That's the one. Mike would know if the Nutter bypass is cool to do in
Ontario. I would think so. Google "Nutter bypass".
