Marqman

Now that the cool weather is back, in the mornings the old Marq doesn't like running for the first 3 mintutes or so. it's a 93 with MANY miles. It's real hesitant and stalls and the idle will rev up and down for a few mintues be4 it smooths out.

Taking a WAG or two here.....

injectors partially clogged, leaning out the mixture until it warms up....

temp sensor intermit

some sort of enrichening injector or circuit issue????? I know some FI's had a seperate injector for whenst cold.... not sure about these things....

So far, ours starts same hot or cold!!! It's a good thing!

Keeping fingers crossed.....

I always recommend getting the factory shop manuals too!

Good luck!
