How do i clean maf sensor and throttle body

Autozone, carquest ect. sell MAF sensor cleaner. Do not touch the sensor because it will most likely break. Pull the throttle body off and spray it down with the MAF cleaner. Brake cleaner is supposed to work but cannot verify that in all vehicles and sometimes carb clean will work depending on the vehicle.

I have a 2000 excursion and sometimes wen I accelerate it starts chocking out at 2000 rpm and won't go any higher

Mostly your MAF MASS AIR FLOW SENSOR needs cleaning.
1st Disconnect the battery ground cable
then open the engine air cleaner.
  • Disconnect the MAF sensor electrical connector.
  • Release the air cleaner clamp.
  • Separate the inlet side from the outlet side of the air cleaner.
  • Remove the MAF assembly.
  • Disconnect the MAF sensor electrical connector.
  • Remove the nuts and separate the MAF sensor from the MAF sensor plate.
As shown

then follow the steps in the video.

if that did not clear your engine chocking then make sure there is no Vacume leak.
hope that helps

OBDii code reads 0170 which is a fuel trim malfunction right bank 1998 mercedes c230 where would the MAFsencor be and how do I fix

The MAF Sensor (Mass Air Flow) is located in the air induction system between the air filter and the throttle body.

Be certain to inspect very well for any air or vacuum leaks in the air induction system or for any loose hose clamps or fasteners in the air induction system, especially between the MAF Sensor and the throttle body. There can be no un-metered air entering the engine or the engine performance will be effected and the check engine light, or MIL (Malfunction Indicator Light) will come on, and P0170 is only one DTC (Data Trouble Code) that un-metered air can cause.

Also, be certain to check for any obstuctions on the air velocity grid to the MAF Sensor, or in the air flow to the MAF Sensor such as a plugged up air filter, or something sucked up into the air intake for the air cleaner assembly.

The MAF Sensor can be removed from the MAF housing and cleaned using carburetor cleaner in a spray can to clean off the fine dust that often builds up on the air velocity sensor part of the MAF Sensor and causes poor performance from the MAF Sensor. (it will require a tamper resistant torx bit, and note the position that the MAF Sensor is positioned in the MAF housing so that it is installed back into the MAF housing properly)

Then clean off the MAF Sensor with the carburetor spray. (From a spray can only, and do not submerge the MAF sensor in any type of water, cleaner, or solvent, or the MAF Sensor will be damaged)

If cleaning the MAF Sensor does not solve the problem, then replace the MAF Sensor and be sure to install it with the air velocity grid facing the air filter, and be sure to tighten all the hose clamps or fasteners well.

Here are a few links to MAF Sensors for that vehicle, and an image to help assist you.

REPLACING mass air flow sensor

The mass flow sensor on the 1999 intrigue is along the intake tube right after the air filter intake housing. Loosen the two clamps that hold the MAF sensor between the Air filter box cover and air intake tube, disconnect the wire leads at the MAF sensor connection and remove the MAF. Note it's uncommon for the MAF sensor to go bad and 95% of the time, cleaning it with MAF sensor with MAF cleaner will fix any problem it may of had to trigger the DTC codes.
Start with trying to clean it first just by following the instruction on the MAF cleaner. This should save you time and money to get your Intrigue running 100% again soon.
Good luck and thank you for using Fixya.

My ford truck failed the smog test because bank 1 and 2 are to lean ( p0171 & p0174 )

possible solutions are, a dirty maf sensor. remove manifold air flow sensor and clean it with maf sensor cleaner. you can buy a can at any auto parts store to clean, take off and clean maf sensor, do not touch inside of sensor it is very fragil. when cleaning sensor be sure it is dry before installing it back on vehicle. also check for a vacuum hose leak downstream of maf sensor.make sure air filter is clean. this usually takes care of the problem. po171 and po174 are the same. you can use electrical cleaner to clean sensor also. also check for a dirty fuel filter and fuel pressure, if needbe.

MAF cleaning

According to almost every manufacturer, it's not recommended or even possible to clean the delicate wires. Of course, they're selling those sensors, so their motivation might be suspect. Try cleaning it first--what do you have to lose? I used to use aerosol carb cleaner, but CRC now makes MAF Sensor Cleaner it's new and less prone to dissolving other components in the MAF sensor. Do yourself a favor and remove the MAF sensor from the vehicle before attempting to clean it. Also, I'd make sure the air filter housing, air filter and all associated ducting are intact, clean inside and not leaking dirt. This will keep you from needing to clean or replace the MAF sensor anytime soon. You have to be gentle because the wires in the sensor are exrtremely fragile. If you poke it with the plastic spray guide you'll ruin it. Let it thoroughly dry before replacing it.
