SOURCE: having problems with my 96 chevy tahoe mass air flow

The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.

SOURCE: Cleaning the Mass Air Flow Sensor

i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.

SOURCE: 000 NISSAN Xterra -- after warming up, loses RPM by 500-1000..... have replaced ignition wires and distributor, checked mass air flow sensor and OK.....

I had a problem on my Nissan Xterra 2000. Symptons sound similar. In my case, it ran fine for a while and then suddenly the engine starts to stumble and lose output. At one point it did not even have enough HP to move. Irregular idling too. Thought it was water in my fuel. Bought water remover from the store and added to gas tank. Problem did not go away. Instead, "Service Engine Soon" light came on. Had to have it towed to the dealer as there was no way the engine could keep up with traffic. Dealer replaced the "Crank Position Sensor" today. Parts $33.00, Labor: $300 (about 3 hrs worth of work). Seems to work fine now but I will wait and see. Dealer also stated that Distributor bearing appears to be noisy and will need to be replaced sooner or later. I will wait for it to go before I fix that.

SOURCE: CODE PO102 after Mass Air Flow Sensor replaced

Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........

P0103
Mass Air Flow Sensor Circuit High Input
Possible causes
Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection
Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
possible symptoms Engine Light ON (or Service Engine Soon Warning Light)
- Engine stall
- Engine running rough
- Excessive fuel consumption
- Excessive smoke
the code is generated when An excessively high voltage from the sensor is sent to Engine Control Module (ECM).

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.

98 SW wagon starts fine but stalls out when put into drive or reverse. Code P0743 comes up after diagnostic check. Says Torque Converter Circuit is open. How do I go about fixing this?

I was definitely gonna say your torque converter. The fix is to replace your torque converter. The convertor basically transfers the moving motion from the engine to the non moving motion of your transmission smoothly. When it goes bad it will usually make the motor run rough in gear or stall the motor when it's completely bad. It will be a fairly expensive cost since the torque convertor sits between the engine and transmission. It also could be faulty wiring as well. You would have to have it physically diagnosed by a mechanic to confirm if its electrical or the actual torque convertor.

P0101 Mass Air Flow, P0300 random misfire, Your problem is the Mass air flow, the P300 is the result of the mass air flow range, Mass air flow is a hot wire sensor they fail when contaiminated, as for the P300 that the engine detecting the condition when the mass airflow range is out, but here is another problem 1998 Buick used a back up its called a map sensor its on the top of intake plenum, make sure its seated and wire connection are there, Now you are going to fix the problem yourself if you ever taken out ,a airfilter and replaced it, then all you need to do is purchase a MAF cleaner mass airflow cleaner or brake cleaner or electrical cleaner clean the inside of your mass airflow you dont have to replace it the code is range performance the hot wire cant clean itself, so someone has to do it

98 ford explorer running to lean, replaced fuel pump, mass air flow sensor and checked for vaccuum leaks. Any suggestions? we are at a complete loss at this point. Please help

spray carb/choke cleaner under intake on mating surface to lower intake. go around the whole intake, dont be shy but spray it.(motor running) does rpm change? if bad seal Usually rpm raises. if so replace intake gaskets, $22.00 parts. Is check eng light on? if yes code check it.although it will only read lean as it cannot detect air leaks. if no code or light carb cleaner is the way to check for air leaks. NOT STARTING FLUID!! I just finished this repair on my 98 tonight, 1-6-11 it runs great, idles also.

Good Day,

Code P0102 indicates MAF(Mass Air Flow) sensor circuit, low frequency detected

Code P0300 indicates Random Cylider miss fire, meaning missfire in more than one cylinder

The misfire could be a result of the mas air flow sensor being faulty.

Hope this helps for now

Let me know what size motor and if it's 2wd or 4wd and I can get detailed instructions for replacing
