Question about 2004 Ford Focus
When car is hot problem starts you stop,go to pull out into traffic,will not speed up or rev up
TEDDY is right on Point. First if this is happening, YOU should not be driving it. YOU are a danger to yourself and those around you and I am sure you do not want to cause an accident or be in an accident.... with that said... I am 95% sure your issue is Transmission Related although Teddy is correct with the other issues that could cause it.
Limp Mode is designed to "GET YOU OFF THE ROAD SAFELY" (you know... Limp Home).... Now that you are home, you need to discover the issue and the vast majority of the time with the Focus is the Transmission Codes. Many of these "MAY" set a CEL but not always, once you start to Scan the vehicle with a Diagnostic Scanner, the issue may be plain to see. Majority of time it has to do with the TCC Solenoid (Torque Converter Clutch)... It could also be something as simple as a Clogged Fuel Filter, MAF Sensor, Clogged Converter are some issues that can cause it.
Scan the Car and you will get some more information.. Something like a P0191....
Let us know what you find out..

Dangerous situation if you pull out & misjudge
things & it goes flat or quits
I would never drive any vehicle like that
Check for OBD Codes,Google them,diagnose them & find a problem
Every vehicle only has about three reasons for LIMP Mode
On a ford it will be to protect the exhaust converter from cylinder
misfires or protect the transmission
Some abs brake systems & stability control systems have a reduced power mode
Do you EVER work on it,several times a year ?
ALL Vehicles require Preventative Maintenance,NOT break
down repairs & you have to look at scan tool data a couple times
a years, to see how thing are doing.

Model years 93 and 94 have the L.H. type fuel injection system. There is also e.z.l.(ignition),a.s.r.(acceleration slip regulation-traction)i.s.c.-c.c.-e.a.(idle speed control,cruise control and electronic acuater),d.m.(diagnostic mod.)and the base module. With a v-12 there is 2 of everything exept base and d.m.. the d.m. mod. overlooks the entire system and the base supplies voltage to the computers. This system is complicated and difficult to diag. Most likley one of your electronic acuaters is faulty. That is your throttle motor. These era vehicles have wire harness issues. Have the car ran for codes starting with the d.m.. at least this vehicle will store faults-the light does not have to be on to read the fault. More than likley you will find an e.a. code. You can have these motors rebuilt for about 1/4 the cost of a new one. Also never attempt to raise idle at one of the actuaters because if they are not both moved at the same time you will lose throttle synchronization and have to have the memmory cleared and resynch. motors. It will cause the exact symptoms like you described-also when the pigtail harness wires short and the modules lose the throttle synch. Good luck

Austrian assembled Cherokee's have a 5 cylinder 2.7 Mercedes motor. These are a serious piece of kit and put the US product to shame. Sadly they still suffer from the usual reliability issues . The worst of which is the habit of blowing the injector seals . As the engine is a tight fit and removing the rear two injectors require dropping the motor, this can be a very expensive problem and can happen as early as 40000kms. Still a great machine!!
