A '72 Djet question, Ug a Uhg a Ug a Options

[Michael J]

Have had my 914 for a couple of weeks now. It's a stock 1.7. It's in the garage getting a few little details taken care of but I need your collective wisdom. The car starts at the touch of the key. It idles at about 2 grand and once its' warm and I drive off it surges all the time. The car has sat for quite a while so I put fresh gas in and some gas dryer. The PO says it ran ok a couple of years ago. He had 18 cars and probably didn't pay much attention. I have been checking all the vacum hoses and they look ok but can't tell for sure if there are leaks.
Your Thoughts?

Change the damn fuel lines in the engine compartment and at the fuel pump ASAP before it catches fire. Old cracked lines spray gas on hot engine parts which burns the car to the ground.

Now, sounds like the AAR valve is stuck open so get sum PB Blaster and spray it into it alot. Let sit, do it again. This should free it up as it rust inside the rotary valve.
Surging driving around hmm, I would guess its old TPS that needs changing. This is evident off idle between 2500-3000 rpms as the car kinda bucks as you step on the gas. The TPS has metal traces that wear out so you get this poor idle to crusin effect.
