I just had these exact symptoms with a 2002 Vauxhall Astra. As well as the Crankshaft Sensor error (and the garage confirmed it had previously thrown out an O2 sensor error). Mine was the EGR valve, with fuels that use a lot of additives (here in the UK that's 'supermarket fuel') the valve quickly becomes caked in carbon. The EGR (exhaust gas ...

Checking a list of TSBs for this set of codes, this looks like a promising candidate: 01-028/04 MAZDA SPECIAL PROGRAM (MSP05) - 2004 MAZDA3 - O2 SENSOR DTC ERROR, P2195 / P2196 From what you describe, a problematic O2 sensor could easily lead to the idling, sputtering and smells that you describe. If the sensor is stuck reading full lean, it's highly ...

When discussing the Throttle Position Sensor You understand it's function electrically on a 5v reference. If you were to take the sensor off and look at the side that goes against the throttle body then you would notice the coil. The inductive loop works as follows. When the butterfly of the throttle body opens (up until wide open throttle) voltage ...

I have a 2005 Hyundai Elantra, and I was getting OBDII error codes: P2626 Hyundai - HO2S Pumping Current Trim Circuit/Open Bank 1 Sensor 1 .. and later, I also got P2196 Hyundai - HO2S Signal Stuck Rich Bank 1 Sensor 1 My car was sputtering, somewhat intermittently. It would intermittently lose power rather suddenly while accelerating. The egine was also ...

The Peugeot 207 petrols have a little bit of a reputation for clogging up on the throttle body. Using a tin of throttle body cleaner and a common bath room tooth brush, remove the hose to the throttle body. Spray in and around the throttle and clean off any 'dirt' with the tooth brush. Hold the throttle blade open and clean as much as possible in and around ...

In most cars, they are exactly the same between banks 1 & 2. In fact in a lot of cars, you could use the down stream sensors as the upstream sensors (this all assumes OBD2). So, yes, order exact for both sides. Secondly, the reason your car runs better when you pull the MAF is the same reason it runs the way it does in open loop. When you pull the MAF, ...

The 50 g/s max flow reading that you are getting is far lower than what merely altitude can explain. The chart above shows that at about 5,200 ft above sea level, the density of air is 83% of what it is at sea level (0.062 lb/cu.ft vs. .075 lb/cu.ft). So to account for the altitude, you should multiply your expected mass flow by 0.83. According to the ...

The fault code P0171 descriptor is Bank 1 running weak. The fault code P0174 descriptor is Bank 2 running weak. This means that your engine has too much air or not enough fuel for proper ignition. This can be a faulty MAF sensor as it is common to both banks. It can also mean that you have an air leak between the MAF sensor and the throttle body, a faulty ...

These motors were plagued by problematic cylinder heads. Usually the end result in cases like yours are replacement of the Cylinder Head. Most likely there is either a blown head gasket or burnt exhaust valve. If there are no vacuum leaks and MAF is good then you need you start looking deeper into the engine.

It could be caused by ignition cables, coils, plugs, I have had the same problem in my Skoda Octavia ยด00, in the morning it was like one of cylinders is not having a spark, combustion was very bad and power was reduces but only for max 5 minutes, then after engine got heated a bit it disapeared, also this problem is related to damaged gasket under the ...

I wish I had a clue or had watched this video before I spent over $600 way back in 2003 when my MAF went bad in my 2000 Sentra. The video should speak for itself: http://youtu.be/vPT8rL0noYg
