2000 Mercury Grand Marquis, 130.000 miles, added gas and it started running really rough and started chocking, service engine soon light came on. Has been running fine so far, could it be fuel filter? Please advice on what it could be as I have no way to repair it at the moment with a mechanic.

It wouldn't hurt to change the filter, but it sounds like you got a bad batch of gas, if it was running good before you got gas.
Get a bottle of dry gas and put it in the tank, if there is any water in the gas, that will clear it out, also it wouldn't hurt to put a bottle of fuel injector cleaner in the tank, I use that stuff all the time to keep the fuel system clean.

All of a sudden my 2004 mercury grand marquis with 55000 miles idles rough. Not really noticeable when driving but do believe there is a lack of power and mpg seems to have declined. Can u help???


The vehicle is 7 years old

The spark plugs should have been changed at 60,000
Gas filter every 3 years
Air Filter every 3 years or sooner
The MAF Sensor cleaned every year
By now the O2 Sensors are slow to respond
If they have 100,000 change the front 2 sensors
Check TPS Voltage
Check Fuel Pressure at the fuel rail
Egr Valve most likely bad
If you have COP Ignition Coils, they may be misfiring,
common ford problem

Unrelated--change trans and power steering fluids
every 3 years,never go over 30,000 miles on any vehicle
