Try changing the ignition control module IF replacing the cranksensor doesn't fix the problem. If the problem still persists check the injectors. They should test at 12V or higher. If they test lower... they need to be replaced. Newer injectors usually sit at around 14V. But start with the crank sensor...sounds stupid and little but it plays a major role in how well the engine runs.

Misfire,stumbles,brake pedal gets like a brick!!! 2.5liter V6 mercury cougar 2000yr


I have ran in to this before as an engine performance and emmission technician.
Sounds like the problem is in the brake booster area is leaking vacuum (air) in to the engine causing a major missfire due to a lean condition. The best way to check this with the engine off and cool so you dont burn your hands. Remove the big vacum hose that goes up to the brake booster and plug the vacum port to the engine. Make sure you get a good seal on the plug and no air is sucking down when engine is running. After that start the engine and make sure it is running smoothly, apply the brakes and see if the engine remains running smoothly. 99.999% of the times the issie is with booster tht when you apply the brakes you allowing vacuum to leak in to engine.
Replace booster and hose with new, do not go to junk yard . By tge way the brake pedal will be stiff because it needs vacuum to make smooth so dont alarm your sekf while testing it.
Good luck and let me know what happens.

Runs rough under load ,stalls and won,t free rev over 4000 rpm. Acts like rev limiter kicks on.


Hi

one of 3 faults

1 MAF sensor also Known as air mass sensor
2 EGR valve, this is most common with the 4000 rev limit and a top speed of say 50 mph
3 air leaks or tears in air pipes or poor seals.

I would be tempted to clean both the EGR and MAF sensor before spending any money though, these parts ofetn work much lonegr when clean

If the engine seems to run fine over 1450 RPM maybe there is a vacuum hose leaking or EGR valve is slightly stuck open. Any help from the OBD II trouble codes? Or is there simply no MIL and no stored information in the OBD II computer read at the local parts store through the connector by the drivers knee?

Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..
