Hey guys!

I de-greased my '76 123 200D's engine this morning using a commercial car engine degreaser.

Following the spray-on, soak for 10mins, then wash off with high water pressure directions, the engine appeared pretty clean!

Problem is, when I started the car, the idle speed suddenly increased (my model doesn't have a tachometer, but im guessing that it was at least a 300rpm increase!). Im kinda lost as to why this had happened. I then drove the car for about 2hrs in stop-and-go traffic, but still the engine idle speed wont drop to its previous level.

Was it because I sprayed too much water? Or maybe the degreaser or water got into some crevice or somethin? The engine was quite warm (not hot, you could actually 'tolerate the pain' if you would rest your hand on the engine) when I washed it, though it did 'steam'.

Also, I've been wanting to know what you would want to put into the hole with the red cap in the injector pump that says 'oel', and how often?

Sheeesshhh! Hope I didn't damage anything.

Thanks for the helpful advise!
