sputtering between 2-5k rpm, low compression?
 

so i am just waiting for my next paycheck so i can go get a compression test. she started showing signs of a neccesary tune up about a month ago. the car was having long cranks to start, massive power loss and sputtering at about 6-8k rpm also moderate engine vibration.

after the tune up; the engine vibration is sorta there and she struggles to pass 2-3k rpm after 1st gear (also only when i drive sportier) if im cruising normally then she drives fine.

i havent checked my cat to see if it's clogged, but i doubt it is because it was replaced 30k miles ago. i have read that a compression test is a must for all 2004 models w/ 80k+ miles.

i want to be ready for the whole fight with mazda about the warranty in the event the motor is toast. i bought the car 6 mos ago with 78k from a private dealer, i recently had to change the water pump and i have done all my oil changes at firestone. in the event of the motor swap am i screwed?


also no check engine light

so the compression test is 98 dollars, is that about average?

That's cheap actually. It's what it should be. They aren't raping you there.


Most dealers charge $300+ for a compression test.
