We have a 2001 Mazda 626 with check engine light on. It has a slight hesitation when starting and then sitting at a stop light for a little bit it starts acting like it wants to die. But then revs up again.
When using my code reader it says 3 things. 1. Cylinder-3 misfire, 2. Bank-1 is too rich, 3. Cylinder-2 misfire.
I changed the plugs and wires. When removing the Cylinder 3 spark plug it had some oil on it. I don't know if that is normal. Anyway after changing the plugs and wires I have the same problem.
I would like to know how to check for a vacuum leak. I don't know what hose to check for leaks.
Please if you give me an answer that includes certain car parts, explain where they are and maybe give me a link to a picture so that I can see what it looks like.
Thank you.
It is a 4 cylinder engine. Whoever gave an answer about vacuum leak, I mentioned in my explanation that I would need photos. I do not know what the items are that you are speaking of.
