Does not accerlerate properly and shakes - 2004 Lincoln LS

I have a 2004 V8

You will have to give me more to go by

You will loose 1 or 2 COP Ignition Coils
a year,not at one time though

The EGR Valve will fail,you can unplug the vacuum
hoses,plug them & drive up a hill to test that

All your testing will be done hot & around 35 mph &
on a slight curve where your off & on the gas & up &
down some

For ignition issues drop down to 25 mph approaching
a hill & try easing up it increasing very slowly on gas
& the coils will misfire & set a PO300 Codes

At 100,000 miles you replace the front 2 (only)
O2 Sensors,as they get slow on the switching counts
New ones will make your car seem new again & instant
throttle response. Only the front sensors,leave the rear
monitor sensors alone,they stay

The Spark Plugs are special to the LS & get replaced every 3 years
not over 60 to 70,000 miles.

Have to use premium gas,or you get a knock,
you can not adjust out

Clean MAF Sensor with CRC MAF Cleaner.
