So when I'm driving it makes a squeaky sound like if something was loose. I checked all around where the tire does and it doesn't make any sounds. It seems just to be when I'm driving. And also when it touches i little dent in the road it sounds like if the tire is going to fall..I'm thinking it might be the lifters.. Can someone help me on this???

The fuel cut-off switch was activated by the impact. Had the same situation. I can provide you with mazda service manual in pdf if you wish.

Hi, Does the car have a problem changing gears? Does the RMP fluctuate rapidly? By the way, I have the same car. I encounter almost the same problem as you. The mechanic put the car under diagnostic and that I needed to change three sensors. Of course I did not agree to that because logically it did not make sense that all three sensor failed. I took the car to another shop, they said the same thing. I am very stubborn so I did not have them change the sensors. I know the problem could be from lack of oxygen or fuel. I decide to clean the MAP sensor. As soon as I clean the sensor, the car start to run like it was a brand new car. The HP increased, the pick up increased. All because the dust built-up blocked the sensor from given an acurate reading. Let me know if your RMP is fluctuate rapidly. Thanks, Mike

tappets dont squeak .. you want to hope the noise is coming from an ageing or loose fan belt .. if it is really coming from inside the valve cover then it could be a blocked oil passage that lubs the cam and its bearings ..this would soon cause a major engine failure .. other possibilities .. a bad bearing in the idler pully, water pump or alternator (a drop of oil on those can help identify the failing bearing) ... also at times the distributor can cause noise if its bearings run dry .. there is a really neat stethoscope like tool that allows you to listen to various parts and places to locat the problem .. but be careful playing around a running engine (no ties, long hair, necklaces .. if its the fan belt then it will likely make more noise as the engine is accelerating .. turning the lights on might increase or change the noise .. a leaky vacuum hose can cause a whistle like sound. .

Just took my car to the shop for the same appearent reason me also thinking it may be lifters. My mechanic said it spounds like a worn wrist pin ...... bad news for you if this is the case .......recomendations rebuild the engine or buy a new or remanufactured one. if the wrist pin lets go then you could throw a rod. If you must drive the car please be gentle
