Fuel injector mystery and manual recommendations Options

[Robson51]

In the process of running down one thing after another, took the ‘74 2.0 out for a drive. Had a miss, so pulled the plugs. This car has spent a lot of the last 9 years sitting, so gas tank has been cleaned and fuel lines changed.

#2 showed where a plug wire was barely attached which was quickly fixed, but the #3 plug was white. I mean really white. Like zero fuel lean.

After looking at the connection to the injector, I saw the boot was ripped and the connection was pretty dirty, so I took i apart and sprayed electrical cleaner in it

Drove it a couple miles, still had a miss, but when I pulled the #3 plug now it was black. Did I wake something up?

Pulling the engine soon to fix oil leaks, so is it worth it to pull all the injectors and get them rebuilt? I have no idea what’s going on here.

On another note, what’s the best manual for a 914 2.0?

TIA

Rob

After you check for a short to #3 injector that might explain the change from lean to rich, it's probably a good idea to have the injectors ultrasonically cleaned after sitting for 9 years.

I use the Haynes manual and Tech Tips from Atlanta Automobile - they both have unique strengths.
