I have an 04 mt 57k miles, took it in for rough idle, and I had a compression test done. Mazda says it's fine. But I have seen too many stories of what mazda says is "fine". I think the numbers are low. But so are my rpm.(time for an updated starter soon)

R1 199 rpm

6.5
6.8
6.8

R2 201 rpm

6.7
7.1
7.1

 

This cold or hot?

B

 

I am pretty positive cold

 

should the numbers be higher when cold or hot?

 

Absolutely higher when hot.

B

 

thats what I thought, but wasn't 100%. I am pretty sure they said they "had to" let it sit for a few hours before running the test.

 

ROFL ? sit a few hours b4 running the test ?


they suppose to test this at hot/warm. Not when its dead cold.

 

they do def look alittle low as do ur rpm's

 

what he said. Mazda did mine cold and warm for the same price where did you get it done

 

Milam mazda in puyallup. It was no cost to me.
