Default Hesitation on Acceleration

Hi I have a 2004 mazda 6 has 112k miles on it just got done replacing engine and I am having issues when accelerating when its below 2k rpm it has a hesitation when I step on the gas. its not throwing any codes and the idle sounds a little off. when i start it its at 1.2-1.5k when I step on the gas it will drop to 800-900 rpm and bounce back and forth. I have changed plugs and wires the guy that replaced the motor was a friend of a friends and might have messed with the timing Any suggestions?

Mannn. Iv got just about the same thing. Is it a MTX? Below 2k it feels like its bogged down. Iv checked for leaks and what not and still the same. I may have missed something though... Ive done plugs, cleaned MAF, new battery(mine tested bad) and new air filter. Next is wires. Any suggestions for wires/whats wrong with my car anyone??

Do you have the AC on? That sucks up some horses and causes a slight hesitation upon acceleration.

Hi, I bought an 04 mazda 6 IS 5-door in December and I noticed it had some acceleration problems and kinda felt like it was lugging at Lower speeds! Read several forums and ally of ppl said the throttle body, but what I tried, was replacing the 2 cam-shaft position sensors( about $35 for both and takes literally 10 mins to change yourself)! Car now runs amazing and gained about 7 mpg's! Try this and let me know if it helps please!

Where did you get the sensors? And could you put up a pic of where they are located? Now i remember A guy at autozone was tellin me something about that. I havent been gettin the greatest mpg either. Thatd be awesome if that 35 dollars does the trick.

actually mine is the 3.0, but im certain they are in the similer location, inline engine, so they would be on your left if youre facing the engine, one on the front cam and one on the rear, if you google your make and model and search for cam position sensor for ex. 2004 mazda 6 2.3 or 3.0, it'll show you where to find them. Nobody carries them, but they can get them overnight. Autozone actually showed me the location on the car, and which one i needed. If you stop by there, you can get your part in a day or so, and get it changed out in no time.. Very Very simple to change, one bolt and one wiring plug. i didn't have to remove any covers at all to get to.. Let me know if this helps you.

throwing parts at it like cam sensors hoping for something good sounds like an expensive proposition.

The cam sensor on the 2.3L is on the drivers side forward on the valve cover under the engine cover
