Re: What is this going into intake manifold?
so with that being cut in half that could be why my car is idling rough and will almost stall at heavy throttle?

You nailed it it's having trouble idling, and when you accelerate it stalls or pings really hard

Vacuum, just get a new line and you should be fine as long as that's the only problem.

warm the engine up and turn it off. Disconnect the est and restart the engine . Loosen and adjust the distributor while using a timing light. I believe the L03 is set to tdc . If your emissions tag is still present it will state the timing spec.

Re: What is this going into intake manifold?
so you cannot adjust the timing with the electronics hooked up to the back of the distributor?
