Saftey feature. Don't be in a hurry.

Can be several things. I want to say spark knock. Don't remember if your engine came with a Knock sensor. Also stretched timing chain or weak timing chain tensioner. Another term to look at is "valve rattle". This would give you closer to a machine gun sound than other things.

HAVE YOU REPLACED THE IDLE SPEED CONTROL VALVE?

bad fuel pressure regulator or possibly the fuel pump

Have a vehicle lift?Easiest way.Have to drain tank,disconnect wiring at tank, remove fill timber,disconnect emission tubes on both sides of car by frame rails,disconnect tank straps and lower gas tank out of car. When reinstalling tank,start the studs for the fuel tank straps by only a few threads so you'll be able to start the nuts when putting the straps back on. Replacing the pump with the tank out is easy. Take the 6 bolts that hold the pump to the tank out,remembering where the outlet on the pump points before removing it from tank. The new pump comes with all new wiring. Just install the new pump and tighten the 6 bolts. Use common sense in tightening them. Having a lift is the easiest way,super dirty,dusty job. Wear safety glasses!

You need to replace the timing chain guides/tensioners. 200-2003 crown vics are prone to that problem. 2004 and up are all okay (with new modified design.)

ac drain pipes are on the passenger side front floor area (just about where your feet go) under car when cars heater core gets a hole in it lots of times antifreeze will leak inside car on floor try to get a small sample of fluid thats leaking out with a tissue or something (white In color) see what color fluid is ,see if fluid is slippery like oil or not (rub it between fingers) Antifreeze= orange or green in color Transmission oil = red or brown motor oil = brown to black washer fluid = Blue or drk orange ac condesate= clear water (cold)

The 1401 code is for a DPFE switch or connector that is not sending the correct signal the PCM expects. The 1288 code is for a temperature sensor which may be showing a higher cylinder head temperature due to low coolant levels, blockage of water flow or bad thermostat.The DPFE gives readings of the mix of exhaust gas returning into the intake manifold to be burned again to lower emissions.The combination of these 2 codes can mean that too much exhaust gas is too frequently going into the intake manifold and is overheating the cylinder head causing the 1288 code. So fixing the DPFE may eliminate this secondary error which may reset itself after the first problem is fixed.

im having the same problem on my 2001 corwn vic pi

Check for EVAP codesMay be a bad evap vent solenoid
