I would pull the fuel filter loacted on the frame and blow through it. If it has any resistance, it is plugged and this is the cause of your problems. Let me know what you find.

When my 2002 grand marquis hits about 40-45 it starts to ****. I thought it might be water in the gas but I have put in seafoam and dry gas with no change. You don't feel it when you are accelerating...

Waste of money to add ANYTHING TO FUEL TANK
Non of those products are necessary or do much

The spark plugs get changed every 3 years or a little
more & not more than 60,000 to 70,000 miles on them

You could have ignition misfires, very common on all
ford products (not from the spark plugs)

I would be disconnecting any vacuum hoses to the
EGR Valve,plug them & see if the problem goes away
If so,replace egr valve. (another ford problem)

The front 2 -- O2 Sensors (ones closest to engine,before
or in the inlet of exhaust converter,get replaced every 100,000
miles. (not all 4-just front two)

Clean MAF Sensor --- in inlet air ducting (between air filter &
throttle body (CRC MAF Cleaner)

While changing Trans Fluid ---fixes nothing --- it should be done on
ALL Vehicles, every 3 years & NEVER over 30,000 miles

Do Power Steering at same time (do flush)

What does a major tune up for a 2004 chevy impala consist of? What should be done and needs to be done?

New spark plugs, oil and oil filter, transmission flush and fill, fuel filter, air filter, coolant flush and fill, clean throttle body plate and bore, clean the MAF sensor, replace any loose or cracked vacuum lines, PCV valve, new air filter, new battery.

99% of the time all you should ever need for a tune up is new spark plugs, and a clean air filter and throttle body. But since your inquiry indicated "major" I gave it more critical thought.

We changed the oil and oil filter, changed the air filter, changed the fuel filter, changed the spark plugs, and put injection cleaner in our 1994 Ford Explorer Limited and we are getting horrible fuel...

Clean the throttle plate-CRC Throttle Body Cleaner
Clean the MAF Sensor--CRC MAF Cleaner

Have the O2 Sensors tested

If it is 10 years old, the exhaust
converter may be plugged,that's
not good and shouldn't happen

Check for vacuum leaks
A leak causes the O2 Sensors to add fuel,
to account for extra air

Make sure the air filter box and ALL
Ducting to throttle is air tight

Excessive cranking before it starts sometimes

Check fuel pressure at the rail

Surely, you have changed spark plugs at 60,000 miles
Air Filter and Gas Filter every 3 years
Cleaned Throttle Plate and MAF Sensor

Everyone does that, when changing their trans
and power steering fluids, at 30,000 miles intervals
