very informational Im currently having this problem with my 2000 mazda
millenia i already changed the plugs and it didnt help much i tightened the
belt and a lot of the time it acts like it doesnt want to start but I will
check my cam shaft timing and hopefully it will fix the problem
How rough was your idle? I noticed my car has a similar problem, the idle
seems rough, but not too bad. I had my engine replaced a few months back.
the idle seemes rough then too. I wonder if it could just be my plugs?
The idle was a little rough but the p0300 code would pop up minutes into a
test drive after clearing the code. If you don’t have codes then check for
dirty throttle body, plugs, and vacuum leaks before you proceed any futher.
Also these engines are known for carbon build up on the intake valves. You
may want to perform a carbon blast (induction service) as well. Thanks for
the comment and good luck!
Cool, hopefully this helps. This car drove me crazy for awhile till I found
the problem. Thats why I wanted to share it with others. Take care friend!
Sorry, I’m in NC. That might be a little to far away to travel. Try to find
a good Mazda tech in your area. I’m sure they will be able to check your
timing marks to determine if your car has the same problem. Thanks for the
comment and take care.
please are you anywhere close to chicago ohio and kentucky,i have had this
problem with my 02 2.5L and the dealers have been ripping me off with no
success
That give me something to think about.
