hey that sucks, yeah its cold as ****, i just did an oil change in like -10 below. beeeerrr! A garage and heater are a must, this was a friends car we did. First what you need to do is get a damn compression test before you do anything else.

will a normal piston engine compression guage work or do i need a mazda only one? yes this does suck, i dont even really beat on my car either,lol damnit :bigthumg:

you can use a piston one, you just have to remove the schroeder(sp?) valve.

sweet casue i actually have one of those,lol thanks for the info man

i'd hate to do one in this weather, it's a bitch to reach the spark plugs let alone remove them and install the compression tester.



also make an effort to count the 'spikes' while you crank it over a known time period so you can calculate the RPM of your compression test. IIRC you take the # of spikes over 15 seconds, and multiply by 4 (to make it a minute) and thats your rpm.



rotor rotates 1/3 the eccentric shaft rate, 3 sides to the rotor, so each spike maps to 1 eccentric shaft rotation... since you are only checking one rotor at a time, so it's easy to just do it for 15 second long and count it, should be easy anyways, not blistering fast. The RPM greatly effects the expected #'s of your compression test.

:bigok: :bigthumg: https://www.nopistons.com/forums/pub...IR#>/boink.gif ok, i just got that, lol , i do understand it though, yes it gonna suck in this weather but my spark plugs are easy to get too, i have no power steering or air conditioning, i ripped all that out and the bracket they were attached too, i really appreciate all the time you people are taking to help me out, no one else around here could even remotely give me this much info you all did in the past hour, thank you, later and keep posting if you know something i dont or something that would help

rock on, I love working on my FC with no AC or PS :bigok:



my friends TurboII pisses me off whenever I have to touch it, no room to even put your hand somewhere.



good luck! don't freeze your nuts!

hey, how can i check the and recalibrate the TPS sensor? also in the haynes manual is the TPS sensor referred to as the pressure sensor, if im correct its the sensor located by the air flow meter on the passenger side? thanks again

Negative, the thing near the AFM is the MAP/Boost sensor.



The TPS == Throttle Position Sensor, it is on the throttle body.



There are a few ways to calibrate it, one involves a visit to radio shack and some LED's and connectors, the other involves a multimeter.

that explains the multimeter way, theres another article out there that explains the LED way, but I have to hurry up here at work and go home, wife is draggin me out. (shes my ride)

kewl, thanks man,piece :bigthumg:
