I can think of a few things that may be happening.

  • The electronic throttle modules (ETM) are problematic. There is a software upgrade that addresses some of the issues, and replacement of the ETM may also be needed. Volvo has an extended warranty on the ETM, so this may be of no charge to you
  • The MAF sensor also fails and causes idle as well as acceleration issues
  • Volvo often comes out with software upgrades for the engine and transmission control modules that address all sorts of issues
  • Also, make sure that the trouble codes are checked and recorded before any work is done
  • Check the transmission fluid and flush the entire system if the fluid is dark or has a burnt smell
Good Luck,
Bret

SOURCE: lack of power

for starters: check clogged fuel filter, check fuel pressure, check for dirty air filter, and check for spark in spark plugs.

SOURCE: My 1990 volvo will not start

1) The fuel pump could be dead.
2) The fuel pump relay (LH models it is located on the driver's side), Regina systems it is located on the coolant expansion tank. Test as follows: turn key to ON and listen for a whirring sound. NG, check the fuse, then check the relay by substitution.
3) Inside the car, the fuel injection relay could also be suspect, but unlikely. Again, check by substitution.

Remember that the fuel pump relay can sometimes fail because of the solder joints making it intermittent. Do not attempt to short across it without the pinouts for the relay - it could destroy the computer outputs along with the computer itself.

You should see a brief stream of gas doing the key test - along with a click of the relay as well with the fuel pump filter disconnected. If all tests good, remove the cover (sedan models) and check the connections in the trunk. On wagon models it is accessed by way of the foldout in the trunk area, then remove the inspection cover, if needed.

black smoke describes poor engine piston rings or worn valve seals in the head cylinders
that will reduce power as well
check your engines oil level daily if driving this way

F22a engine produces strange noise most obvious at 2000 rpm, what could the problem be?


Without a general description of what the noice sounds like, squeal as compared to knocking, it is impossible to help you. Engines make a lot of different noises, so try and help by describing noise. I would suspect it is belt related, or tension pulley related as these are RPM variable noises, belts tend to slip when you accelerate and can be quite loud with a serpentine belt as example.

You have a mechanical bind. Disconnect the main linkage and work it all by hand. Everything should be free and slopy. Aerosol carb cleaner will help, but only when the engine is not running.

- TP sensor not seated properly.
- Faulty Throttle Position (TP) sensor.
- Dirty throttle body
When is the code detected? The Powertrain Control Module (PCM) monitors operation rationality check by comparing sensed throttle position to mass air flow readings
P0068 DODGE Description The Powertrain Control Module (PCM) monitors a vehicle operation rationality check by comparing Throttle Position (TP) to Mass Air Flow (MAF) readings. If, during a self-test, the comparison of the TP sensor and MAF sensor readings are not consistent with the calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
