So Im driving home tonight from my friends and it start to stutter, loses power to the point I can barely if at all accelerate, and the check engine like keeps going on and off. Then as I turn down my street I get full power back.
Now this has been a current problem for the past, oh month or so but nothing like this. It usually stutters then it will clear up and accelerate as normal or just have half the normal power at times. Since this problem started I changed the plugs and wires, air filter, fuel filter, and injecter cleaner to try and fix the problem, none of which worked. I researched the problem a but on the forum the only other thing suggested was TPS but a old Master Mazda Tech/rotary head checked it and said it was fine, which leads me to my question. Has my engine finally blowen? A local mechanic has a Mazda compression tester so Im going to take it to him to be sure just thought I would get some others thoughts on this problem.
Well thats all I guess, any help would be appreciated.

it's easy to tell if it's your motor... check the compression!

Btw if you have some power sometimes and lots of power at other times - it's probably not your motor. Generally you have almost no power, all the time.

YES the battery cable. Now that you mention it every once and awhile after I park it and come back it wont start because the cables not making a proper connection. So Im guessing thats happeneing now when Im driving. Thanks a lot guys.

i had the same problem, an incredible stutter at times. it was my negative battery terminal. stupid terminals.

Emery cloth on the terminals will work wonders.

Thanks guys that turned out to be the problem. I cleaned the terminals and connectors and tightend them down again and runs like normal now. Still feels slow though, curse of the stock N/A I guess :P
