Running with cold temp, & loss of power.
Latly my n/a has been acting up. It has been running 'very' cold (making me worry). I don't smell gas, no 3800 hesitation, crappy throttle responce. Have checked everything I can think of. I have not tested my MAP sensor (not sure on how to, although i do have the values and instructions I dont have the tool to apply the vac pressure) Althuogh I did test my TPS, It was within tolerance (ohms) but when I goto adjust it with 2 digital multi meters I get 12V on one and cannot (no matter the adjusting) can get 12V on the other meter (only time i see the 2nd meter move is if it's 2500rpm or higher). Would that be a bad TPS sensor or could the signal of another sensor be making the TPS adjusment impossable.??

When you say you're running very cold, I assume you mean the temp gauge is not climbing up to where it's supposed to sit? If it is running cold, the ECU will be causing rich mixtures. This will give you crappy throttle response among other probs. This could be a stuck open thermostat. Check it and change it (genuine Mazda only) if it's not working properly. This should fix it.
