SOURCE: I have a 2006 Ford Expedition. The Air

you have a vacuum loss to the ac control head, the motors that divert air are vacuum operated, if you loose vacuum the system goes to defrost for safety reasons, the vacuum comes from the engine, then goes o a plastic vacuum tank under the hook start there, it is a 3/16 id hose.

SOURCE: front heat works, but rear blows cold air only

With your front heat working the most likely cause for the rear heat not to work is that there is an obstruction in the line that is preventing the warm coolant to get to the rear heater core or the rear heater core itself is plugged and not circulating. Another possible cause could be low coolant level where the system has enough coolant to provide the front system with enought warm coolant but not the rear system. Hope this helps

First, check your engine coolant level. If it is low, you need to find out why. If the coolant level in the radiator is full, it could be many things including a bad thermostat, a clogged heater core, or a broken or damaged air temperature door or actuator.

I cleaned the injectors on 2006 yamaha vstar 650 got a little more power but when I open full throttle and release it some it is surging what could be making it surge now?


Hi, Peggy try running a can of fuel stabilizer (Sea Foam) in the gas tank otherwise the usual suspects are:
1. Extremely lean fuel mixture.
2. Dirt, rust, water, or ethanol sludge in the fuel system.
3. Sticky throttle cables.
4. Multiple carburetors not in synchronization.
5. TPS sensor out of adjustment or faulty.
6. Wrong spark plugs for the type of service.
7. Throttle bodies not in synchronization (FI)
8. Faulty O2 sensor.
9. Clogged, stuck, or faulty IAC valve.
10. Aftermarket components not compatible with ECM.

Front cylinder misfire at idle,then raise rpm's to 2000 area an it comes in an out popping thru exhaust.front cylinder cold to the touch when rear is hot, till it runs a couple of min. New plugs, good...


I am not sure if the bike is a 650 or 1100 but in either case it sounds like a fuel issue or and air leak. When the carbs were off for re-jetting did they get cleaned? The slow circuit controls to about 2000 rpm and it sounds similar to your problem.

The first thing to look at is the carb synchronization. If the front cylinder is lagging, it can give the same symptoms. I do not think that the exhaust is a factor because the front is cold when running.

Spray some WD 40 at all the intake manifold area when the bike is running and see if the idle changes. the idle will change and push some smoke out of the exhast if the intake is leaking.

If both of these check good I would pull the carbs back off and clean the slow circuits out completely. This is delicate work and shoud be done by and experienced tech.

If I can help some more just send message.

I hope that his helps. Steve

this symptom resembles an intake leak. Check to see if your intake seals are not leaking

Motorcycle running on one cylinder


First, determine which cylinder is bad. Touch the exhaust pipes to determine which is hotter.(the pipes get VERY hot so be quick or use a non-contact thermometer.)
Remove and look at the bad cylinder's plug, if ti's wet you are getting fuel, try replacing it. (Heck, replace it anyway.)
If there is no fuel on the plug the carburetor might be plugged or need cleaning.
