Please bear with me, a relatively new owner, but willing to invest the time to do the fixes correctly.

I am trying to get all material together to replace all vacume lines on My 928. I do have many vac leaks, since the PO was nice enough to have a seriously shody mechanic work on it. I have alot of work in the future to do. Right now there are 2 styles of vac lines on it, rubber and plastic. Not my doing..

Also curious what connectors are recommended, plastic or brass for long term life.

Question #2, My car rough idles, like it's missing or dropped cylinders when idling. As well as pick up is not adequate, very sluggish. Is there a tool or test that I can buy or do to check for bad plug wires? No, there are no sparks at night under the hood eminating from the wires.

Thx

One way to read the condition of your engine is to read your spark plugs .the condition of the electrode on the plugs tells the story, rich, hot, oil, etc. any Haynes manual has a spark plug chart. A in line ignition spark checker is the tool you need, never ground the plug to ck for spark. You can also ck spark plug wires with a DVOM; typical measuremements are 1000ohm per inch.

You engine performance could be related to vacuum leaks. Start repairing the vacuum leaks and then see how the engine performs.

I found one open vacuum line which made a dramatic improvement in idling once I repaired it.

Good luck.

 

Appreciate the hint about the DVOM. Started last night with the vac lines. Still curious, should I replace the vac lines with plastic, or rubber, or should I use high performance interior braided vac lines. Seeing the amount of time I am spending, some are PITA. Have a leak under the FI manifold, off it comes.
