Remove the plastic coil cover from the middle of each valve cover. Remove the coils. Unscrew and remove the spark plugs. Installation is the reverse....

If you have wires, you have three coils and not six and you've actually got wires. To remove one end of a wire, first twist, then pull. If it won't twist, use spray silicone lubricant.

You may have a large plastic beauty cover over the top of your engine. If it's in the way, remove the four nuts and the cover.

thanks.

I got a 97 vision 3.5. i have bad gas mileage (about 8-10 mpg) what all can i do to help improve that?car also overheats only when idling anyone know causes for this?


When is the last time you had a tune up? Have you changed the spark plugs lately? An often overlooked item is the air cleaner. A plugged air cleaner can take 3 or 4 miles a gallon off your average. You can purchase a K&N cold air induction or a cheaper brand, this includes the cleanable air filter and chrome air intake hose, replacing the stock. This should improve your gas milage by 4 or 5 miles per gallon.

Location of the EGR valve/DPFE pressure sensor


What engine? It won't cause any running problem but gas milage will be effected just because the light is on. Ford computers change parameters when the light is on and mileage will drop 1-2 miles per gallon.

1987 cadillac gas milage went from 15 miles around town to 8.5


this is what I would do. I have the 1993 model and get 22.5 to 23 miles per gallon.
I would change the plugs, change the plug wires, change the fuel filter, change the air filter.
if you have done this lately then one overlooked item would be the coolant thermostat.

when you first crank the car and the engine is not warmed up, it runs in a "closed loop" mode and it gets bad mileage. the computer doesnt care about mileage at that point, it just wants it to run good.
after the coolant gets up to temperature, there is a coolant temperature sensor ( should be located screwed into radiator somewhere) that alerts the computer it is up to operating temperature. the computer then goes into a "open loop" mode and the computer then constantly changes the air fuel mixture to make the best out of emissions ,milage, and power,...
so, it it is not getting up to temperature it could be the coolant thermostat is stuck open. if you cant remember when the last time its been replaced then you may want to go ahead and do it.
if that dont work, it could be the coolant temperature sensor itself.
When I was carpooling in my caddi I drove 7 miles down the road to catch my ride. I get 15 miles to the gallon. and spend more on gas then if I just drove by myself. when I drive to work my self (35 miles) I get 23 miles to the gallon with stop and go averaging speed of 50

Lost gas mileage please


Lost gas mileage. I would have to assume that you are not getting the require mile per gallon. For example If the car book say 32 miles per gallon. You are getting about 20 to 25 miles per gallon.
If you want to improve the your gas mileage then you have to do the required maintenance
Oil change every 3000 mile
tune up as required
Air filter
If the wiring spark plug wire is old and crack then it need to be replace.
If you park out side and the batteries is about 5 years old have it check
If you buy the car new, you will have a car book follow the maintenance routine.
If you have done all the maintenance and the gas mileage is low than recommended then take it to a shop to figure out if some thing is wrong or not preforming as it should.
I do hope this help you.

Wide tires make less gas millage, get narrow wheels, let the car accomplish speed slowly from 0 to 30, look at air filter,if shortly replaced, oxygen censor, 15 miles is normal 16 miles per gallon is good for a V8

Check the torque on your plugs, should be around 15 - 19 lbs - consult spark plug manufacturer on the torque - if you did not torque them enough, they may have become loose. Also check coil packs - make sure all plug wires are snug.
