You also have a deceleration valve, throttle switch, air flow sensor switch, frequency valve, acceleration enrichment control unit, Lambda Emission Control, and a pile more sensors on your engine.
Shocking, isn't it?

Get the Bentley SC Repair Manual, you'll love it.
It explains how these components function.

Find yourself a mentor on this forum. List your location. I'm sure a fellow Pelican can help you.

It's impressive and shocking...thanks guys for taking the time!

Let's not forget about the ICV (Idle control valve)

No ICV.
He has an SC with CIS, not a Carrera with DME. :)

Point taken.
I posted this because a few Carrera guys have chimed in with the same problem. I should have been more specific.
I'll be taking my 86 Carrera in for a CO check etc to Tuesday and will keep everyone posted.
Thanks
Rod
