Clicking sound,low rpm idle, and

Get battery checked possible dead cell

if you have low compression the engine will need to be repaired, ie new rings possible more

Dwight, sounds like you are having some trouble with the torque converter. Check the fuild level and maybe even change the fluid and filter. When it does shift does it shift normal or hard?

sounds like its a different sensor causing problem. could be TPS SENSOR OR MAP SENSOR .

you should check timinh tensioner. thats probably the problem...

It sounds like a failed 'idle air control.' Your computer may be monitoring engine conditions so having it scanned at one of the chain auto parts stores may identify the problem. The scanning is (in my experience) free of charge but call first to confirm this.

i think you have a vacumm leak po 170 is a lean code look for leaks also check and clean mass air flow sensor and you may have to take to dealer for that throttle screw that does not adjust the idle speed take carb cleaner and carfully spray around engine when running listen for change becareful around coils and exaust.

here are a few problems to look out for:

Check-engine light: Check engine light comes on due to carbon buildup on the exhaust valves of 2.5L engine. (1995-02)

Engine noise: Some engines make a metallic tapping noise requiring a new friction-gear spring on the camshaft. (1995)

Headlights: The headlight drain hoses can get kinked by the aiming screws causing fogging. (1995-96)

Keys: It may be hard to turn the ignition key because the steering shaft is not positioned correctly. (1995)

Steering problems: The steering wheel may be off center requiring adjustment of the tie rods. (1995). You can also have a look at the following website where some owner have given their opinions on owning one. http://www.carsurvey.org/reviews/mazda/millenia/r68654/comments/

check the rubber air intake hose for cracks or breaks.

check engine light flashing usually means a misfire. i would have to to run a diagnostic check first. i would recommend getting it put on the computer at autozone (cause it's free) but i don't know for sure if they can run that year model. i know they run 96 and up. but you need to find out what cylinder is misfiring and i can almost bet you its a coil pack or injector. if autozone can't do it you'll have to call around to your local mechanic shops and find out who charges less to put it on a computer, usually $75 or more. i have one i would only charge you $50 but that doesn't do you any good lol.get back with me and let me know what you fid out.
