Being electronic ignition, the timing should not be out.
It is more likely there is tight valve clearances, this will cause backfire and poor fuel economy and poor idle. also if it is not corrected it can burn valves and seats.
solution
full tune and service with valve adjustment.

2016 Harley Davidson Electra Glide Ultra Classic is getting poor gas mileage


Hi, Jack my email address is at the end of this novella you can elaborate there. The following tips are low cost easy to apply/install and guaranteed to give you better gas mileage and a smoother running bike. The average motorcycle gets 35-40 MPG. saving .2 gallon of gas could save you a 6-mile walk. 125cc scooters have been known to get 115 plus MPG
1. Proper tire inflation as per MFG. specifications wheels should be balanced and spokes tight.
2. Oil and coolant levels maintained at full marks, low levels produce excessive heat that causes the engine to work harder and reduces efficiency.
3. Keep extra weight to a minimum.
4. Take off from a dead stop should be smooth and easy throttle applied avoid excessive throttle snaps.
5. Smaller windshields get better MPH than large ones, wind resistance increases as a square of the speed at which you're traveling. For example, at 70 mph, wind resistance is double what it is at 50 mph (70 squared is almost twice as much as 50 squared). That will dramatically reduce your mileage. Keep that in mind while biking.
6. Keep idle time to a bare minimum or turn off the engine.
7. Re-jet carburetor with a smaller main and mid-range jet.
8. Keep chain/belt properly adjusted.
9. Avoid quick braking, hasty acceleration, high-speed driving, try driving the speed limit and keep a constant speed.
10. On long trips use freeways or flat straight stretches of highways rather than city or rural routes avoid hills and mountains when possible.
11. Keep your engine clean, dirt and grease/oil hold in heat.
12. A full-face helmet is more aerodynamic than other types of helmets. Any other clothing that decreases your aerodynamic should be reconsidered.
13. Any unnecessary bling on your bike is going to decrease fuel efficiency.
14. Use high-quality fuel using low-quality fuel can cause sludge in your fuel injectors.
15. Keep warm up time to a minimum get off the choke ASAP.
16. Motorcycles run best when their engines are maintained, and that includes making sure the air filter is clean, the spark plugs are fresh, the fuel filter is free, and the timing/valves are adjusted.

I have a 95 f150 and it has a tendency to idle at 1100 rpms in park. i clean the idle position sensor and that didnt help. also it seems like it has no power when i drive it and i'm not getting very good...


symtoms of a bad coolant sensor. poor idle, stalling, rich mixture, retarded timing, low idle speed, cold hesitation or stumble, poor fuel milage. ( will also ****** timing ). in some cases you can unplug sensor and the pcm will compensate by running a default air/fuel ratio and in some cases allowing car to run without the sensor.Id just replace it !! if light is on, get vehicle scanned to find problem code. most all auto parts stores will scan for free, auto-zone etc. have a good day !!

What grade of fuel are you using? There are many conditions that effect gas mileage. The way a vehicle is driven, is it shifting correctly, flooring it to get up to speed from dead stop also known as Jack Rabbit starts, driving with the defroster on when it isn't needed or the setting just above that can be used. Back in the 90's most car manufacturers made a change to their heating.cooling system that caused the AC compressor to kick in when the selector was set to defrost. This puts drag on teh motor and decreases gas mileage. Build up on valves and low compression in the firing cylinders will cause you to lose gas mileage as well. Do a compression check on the motor to make sure you don't have abnormally high compression or low compression on cylinders and use a bottle of gas treatment in your fuel to clean some of the carbon build up from injectors and valves. Also start using the Mid grade fuel. Not the High Octane in your area. In Texas we typically have 3 choices 87, 89 and 93 to choose from. Low grade is enough to run the vehicle but performance is low as well as mileage. I use the 89 octane for better performance and better mileage. The High Octane or 93 isn't really good as it leads to higher carbon build up on the valves. Also check your oil often and make sure your changing it every 4000 miles at the longest. All of this along with making sure you change the Air Filter every 5000 miles will increase your mileage.

Ford fusion 3 1600 diesel cam belt mileage change


75,000 miles for heavy urban city driving.
100,000 miles if you drive a lot of freeway.
Mix driving should be under 90,000 miles.
If your the timing guide (on the side of the timing belt cover) making noise then you should change it ASAP.
A loose timing belt will offset timing on the injector and decrease mileage.
