For VW Golf TDI:
If the car goes in "limp mode"!!!
After scan the EDC-15P engine control module with a VAG-COM or BOSCH KTS diagnostic tool connected to the data link connector of the car, (placed on central console under A/C controls behind a plastic cover), you will find this: Fault code: P1557-Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increase too much and ECM (engine control module) go in "limp mode" = engine protection software. As a result the "limp mode" engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault still remain in ECM memory!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.

A problem my 2003 Altima runs but has lost power car is manual and shifts into gear but no power


You are most correct. Chances are a slipping or stripped clutch disc.

Tip

Loss in engine power, sluggish responses, low top speed, etc.


If your car has
  1. Poor fuel responses
  2. Lost its "power"
  3. Low RPM
  4. Lower top speed
  5. Burns a lot of fuel
Then it could be because of carbon build-ups in your engine's combustion chamber. This is left behind with unburned fuel. It causes poor acceleration, a loss in power, lower top speed, and burns more fuel than it really has too. Not to mention causes smoke belching.

The best way to get rid of that would be to have a carbon ridding solution injected into the combustion chamber. The solution will liquify the carbon and other build-ups, which would then restore the "power" of your car. You'll get better acceleration, higher rpm and top speed, save fuel, etc. have a mechanic do it for you. It's alot cheaper and faster than having the engine overhauled (overhaul could trigger "loose compression").

Check engine fan operation and make sure radiators not packed with dirt and debris.When your on the highway you have the speed you are traveling at air cooling the radiator.

all gas engines.
1: lost 12vdc power to EFI system.

3: lost spark.
4: bad fueling, flooding stalls or lean stalls.
there are simple test for each and takes tools, got tools, ?

Vehicle drive smooth then all of a sudden the wheels starting to tighten car slow down.


what makes you thing the tires/wheels tighten (felt by hand off ground?)
my guess , you meant it seems. like???
1: lost engine power?
2: transmission not up shifting?

is this a auto A/T or manual M/T tranny,
if A/T , you need to look at the engine RPM when you lose
power (acceleration on demand)

RPM rises, car dont move faster ,this is tranny slip.
RPM fails to increase, and speed, up hills. this is called lost engine power.
lost engine power can be caused by , bad spark (tuneups skipped?)
or weak fueling.
weak fueling too can be cause by skipping the fuel filter step in the tune up list.
