Hi and thank you for your question. My name is ***** ***** I'll do my best to help. Can you explain to me what you experienced? Did the vehicle suddenly stall, run rough, or just lose power? What makes you think the vacuum lines are the issue?

Customer: replied 10 months ago.
The vehicle ran just fine. My son was with me and he finally found a active vacuum line that made the transfer case kick in.
Customer: replied 10 months ago.
I'm a little broke if you don't mind.
Expert:  TODD RUZICKA replied 10 months ago.

ok, I don't think the line you are referring to could cause the engine to stall...did it just stall or run rough first?

Customer: replied 10 months ago.
It ran fine. Just noticed that the front tires did not move.
Expert:  TODD RUZICKA replied 10 months ago.

Did they not move while driving straight or turning?

Customer: replied 10 months ago.
No they did not turn at all.
Expert:  TODD RUZICKA replied 10 months ago.

Sounds like the vacuum line leak has actually caused the 4WD to engage...has the vacuum line been repaired?

Expert:  TODD RUZICKA replied 10 months ago.

The 4WD system on that vehicle is controlled via vacuum.

Customer: replied 10 months ago.
No I need to get under the hood and fix the vacuum lined.
Expert:  TODD RUZICKA replied 10 months ago.

ok, once you fix the line let me know how it operates, ok?

Customer: replied 10 months ago.
Ok
