Hi guys
I have Mazda 6 , 2003 , 2.0 Engine
Today I checked spark plugs
while engine was running I removed plug wire one by one. (mean remove 1 and check then put it back then remove 2nd put back,.............................)
so the result was:
1 plug wire remove engine loss power but running
2 plug wire remove engine loss power but running
3 plug wire remove engine loss power but running
4 plug wire remove engine loss too much power near to stall

What does it mean ??
Are 1 2 3 plugs are faulty?

any Idea !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Have you ever changed the plugs yet? When was the last time they were changed. The car is old. Change all of them.

change all the plugs. when buying used..my practice is..

-oil change
-plugs
-air filter
-fuel filter

thats a minimum. and if its an auto, i actually do a flush and refill. that way i know its done.

+10 except the fuel filter state side is kind of unservicable. such none sense.

ya i think so no need of changing fuel filter
