Default hesitant 1986

I have a 1986 with 160,000 miles which has a couple problems.

1. During cold weather, I have to use starting fluid to get it started. Starter fluid isn't necessary during warm weather (50 degrees and above).
2. Under load, the vehicle gets bogged down and can't get out of its' own way.

Anybody have any idea what the problem is.

Hmmm.... I can't imagine how you're spraying the starter fluid in there, but anyway....

Let me start you in the right direction and maybe someone else can give you more info:

On the driver's side of the engine, you'll see the fuel injectors - 4 of them. But there's an extra one that appears out of place - somewhere between the 3rd and 4th ones. That's the Cold Start injector.

Ok - now someone that's worked on this can take it from here.
