2001 Mercury Couger V6 vacuum pipe from module under battery is not connected

I just bought this car, and while ideling, the engine races and then slows. I suspected a Vacuum problem, and on inspection found the pipe from the module under the battery is not connected at the other end. I can't see any place that it should connect to. One end goes to the module under the battery tray, where does the other one go?

Best suggestion is to get a Haynes repair manual that covers your car. There are vacuum diagrams in these books that should points you in the right direction. Given that it idles in a rather manic/depressive manner, I'd look to the carb/TBI/Fuel injector system for a vacuum nipple.

Petrol Car Engine OFF when Press Escilator

Have you checked the timing? It might be too advanced. I would try to retard it just a little. I would also check for vacuum leaks in any of the hoses going to the carburetor or the distributor.

My 1994 buick road master out of California get only 16 MPG. I had a 1992 buick roadmaster out of north carolina that averaged 28 MPG. How do I get the 1994 car to get better gas milage. My machanic say...

Things that can be wrong as long as the car rools fine are the timing chain and exhaust restrictions or leaks. Dirty or leaking fuel injectors can too if the car has good power and doesn't lag at off idel ( like a timing chain loose will do ) oil pressure or too heav oil or oil that hasn't been changed. low tire pressure is worth about 3 MPG Timing chain can be 10 easy as stopped up exhaust. the car runns stronger with the pipes unbolted from the engine then theres a converter or muffler problem. If the pipes are good it'll not make any different except it'll sound like a race car. ( might seem faster but it will be faster if the pipes are stopped up. Race cars go faster with open pipes as the engine has been modifed to run better with open pipes but an ordianry car will have little difference until it's revved up real high.

After starting, idle will not drop below 1500 rpm engine races. apparent vacuum leak. how do I locate this leak?

Easiest way to check for a vacuum leak is to spray some carb cleaner where you suspect a leak and engine idle will change.

I suspect your problem is with the IAC. Try changing if you can't find a vacuum leak. Cheaper to check for leak first.

Let our Experts solve your "when at idel rpms quikly drop and car stalls" Problem

Almost always a vacuum leak. Especially suspect is the vacuum "boss" located near the back of the engine. Make sure all those little hoses are on their nipples, and that the hoses themselves are not cracked, etc.
