Disconnect the actuator and see if the problem goes away. If it does, replace the actuator. If the problem persists then look at MAP sensor as the possible culprit

SOURCE: 1995 nissan maxima bogging

My 95 did this exactly to a Tee. After trying several things, like cleaning/replacing MAF, fuel injection cleaner to no avail, I ended up unplugging my battery overnight to reset the ECU. The next morning, I put cleaned old MAF and put it back on. Then hooked up battery. Started up, no bogging at 2000 rpms, no stalling, etc. The new MAF was an aftermarket that I bought on Ebay for $86. My car didn't like the aftermarket MAF, so I wouldn't recommend. Anyway, that was 2 weeks ago, and everything is still running good. Hope this helps.

What might be the problem when a bmw 335 e90 loses power while driving even on takeoff


Possible problems could be weak high pressure pump, weak turbos or vacuum control problems for turbos, carbon on intake valves, worn spark plugs, or even restricted air filter.

My car 's engine is searching an it strugle's to rev up or while I drive when I apply accelerator the car loses its power


This can be related to a couple of issues, the most common of which are:
1. Fuel delivery problem (e.g. the fuel pump produces too low fuel pressure or the fuel pressure regulator can be shot or the injector(s) may be clogged). When you step on it, it leans out and has no power.
2. Air delivery problem or air metering problem:
- a clog in the air intake (I've once had a mechanic leave a rag in the air filter box and the car wouldn't want to accelerate)
- airflow sensor
- map sensor
- throttle position sensor
3. plus, the searching can be a symptom of a shot idle air control motor (stepper motor), but this won't fix the loss of power so I'd suggest leaving it for later, after the loss of power problem's fixed.

What causes the manufacture control fuel air metering to go bad?


Please check:
- Fuel pump pressure. (38-44 psi)
- Check fuel regulator.
- Fuel filter.
- Sedimentation filter in the fuel tank.
- Fuel injectors.
- Water contamination in the fuel tank.
- PCV valve for open or clogged.
- Vacuum leaks in the intake manifold or vacuum pipes.
- Ignition system.
- Brakes for partial engaged.
- Reset ECM.
If problem persists, pull up the live data with scan tool and interpret the results.

Intake noise


has it always done it? do you have an aftermarket cold air intake on it? if it has always done it...i think u r talking bout the vacuum relief of the intake manifold. no big deal

Po108 service code


Hi,
OBD II Fault Code
  • OBD II P0108
Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor converts the Intake Manifold air pressure into a voltage that is high when the Intake Manifold air pressure is high and low when the Intake Manifold air pressure drops to a vacuum. The P0108 code indicates a high voltage input from the Manifold Absolute Pressure Sensor/Barometric Pressure Sensor to the Power Train Control Module.
Symptoms
  • Check Engine Light will illuminate
  • In many cases, no abnormal symptoms may be noticed
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • In some cases, noticeably poor engine performance may occur
Common Problems That Trigger the P0108 Code
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  • Intake Manifold vacuum leaks
  • Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections
Common Misdiagnoses
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
  • Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

My 1992 corvette does not blow hot air. I can control air flow.


Is the inlet and outlet heater hoses hot and if so you have a seperate acuator for your hot/cold door.Check for vacuum there if you have vacuum to the acuator then it must be a faulty acuator or jambed door.

Car loses power when it gets to about 80Mph


the boost controller works by vaccum pressure on some turbo engines and if it loses vaccum to the controller it dumps all turbo pressure out exhaust instead of intake. I would check that if it were me. It could be the mass air flow though it is located in the breather tubing somewhere between filter and the intake manifold.
