check you vacuum lines
Where are the vacuum hoses on a 1995 ford thunderbird 4.6l engine?
You probably have a vacuum leak.
The hose going to the brake booster is a great place to test vacuum.
Front about 3.5 pints rear about 5 pints.
yes. you may end up with a wire or two that goes to nowhere but the basics are there and the vacuum lines are the same. i have a 91 with a 92 motor and there are at least 2 wires to nowhere but it doesn't affect the jeep at all. your check engine light may stay on but it is probably because of the wires that aren't connected. no big deal.
If it has square headlights and leaf spring suspension on the front end then it is a YJ

The vacuum switches for the AC vents on a 1995 GMC Safari all-wheel drive van are located underneath the dashboard. The vacuum lines are also located underneath the dashboard.
yes.
Check all vacuum lines for cracks or leaks, and replace as necessary. I would just replace all vacuum lines. Replace the plugs and plug wires if you have not done so.
On the firewall, in the center right above the valve cover. It has a vacuum line connected to it and a 3 pin weatherpack connector.
