Is your car feeling abit slugish, idle feels abit shaky, midrange power dont seem to feel like it use to be (or how it should feel like from factory for those of you who bought the car used), your automatic gearbox seem to search for gears on the highway?? plagued by the occational dreaded Check Engine Light (CEL) or Transprogram Error (EGS) or the LIMP mode coming on? Try cleaning your sensors... my car felt fine and smooth but the OCD in me just had to try it. so I ordered a can of dedicated CRC MAF cleaner from the NET and a electronic contact cleaner from ACE a few week back. since i was free last last weekend, i decided to take some time pampering the car, started with removing the MAF from the car, then I blasted the hell out of my MAF along with some q-tip fingering, be VERY gentle as the wire/film is very delicate and fragile, do this at your own risk. you may skip this step if you wish. i was amazed how black and dirty the tiny sensor is even though its only been a year plus old since replacement. after that, just let it dry throughly and install it. started the car, it felt a world of difference. the engine felt and sound smoother, took it for a spin on the highway, the difference in engine responds in apparent on all gears. on the way back i remembered i had kept the old MAF (was changed coz of a MAF out of range fault code), first tried pluging it into the car, started it, but it felt like crap, so clean it with the MAF cleaner and try it again... wow its CURED, it felt like the new maf ..haha ..a spare maf in hand. test drive the car with a full tank of fuel. recorded the mileage as a guide for both MAF.this weekend i decided to clean the Inlet Air Temperature (IAT) Sensor as well. (This task is quite tough so its not recommended to those unfamiliar with your engine.) first remove the wire harness from the sensor then remove the IAT from beneath manifold. my sensor was covered with oil and vanish. wipe off the excess oil from it with a cloth. then dip the sensor in some kerosene (if you have any) or spray liberally with WD40 to disolve any remaining engine oil from its tip. wipe dry. then spray the sensor with the electrical contact cleaner to remove all traces of oil&solvent, let dry. Reinstall. remember to replug the wire harness. started the car, engine felt the same on idle. took it out for a test drive on the highway, the result is a much better responds across the rpm all the way to redline. tested car with a full tank of fuel and mileage recorded. improvement as follows based on a full tank of fuel and usual driving styleost MAF cleaning +30km additional mileage, rpm rev up faster n smootherPost IAT cleaning minimal/neglegible mileage change but the car felt more responsive, possibly due to better ignition timing with the proper IAT readings.spare some time to do the maintenance and feel the difference, you engine will thank you for it. Do note! for m54 and newer engines, your IAT is incorporated in the MAF housing as a single unit. so you wont have to do the second part. parts required as follow:-crc MAF cleaner crc electrical contact cleaner screw driver + - rag total diy expenditure > RM 80....Disclaimer:the above is only recommended for knowledgeble DIY gurus. i am not liable for any misfortune you may encounter due to your own stupidity. those who are too pampered and wussy about doing this kinda thing to your car, or cant even be bother getting your hands dirty, dont even think about it. to those who dont even know what are the parts in your car, its functions etc. .. stay far away and go seek professional help. and to those with nothing good to contribute to this post..SHUT UP!
