industry standards for compression is no more than 10% between cylinders which makes the 90 lb/sq" should be 117 at worst.. If the head job was done properly then a replacement engine is indicated as there is a ring problem in the low cylinder. Rough idle is an indication of a vacuum leak and if the brake booster is not assisting I would be looking at a leaking hose connection between the manifold and the booster Idle rpm is around 900 for a mazda. Check for faulty pc valve allowing excessive air from the sump and not shutting off correctly.

Most likely your throttle position sensor is faulty. You could have a vacuum leak as well. Most probable cause is a bad sensor. Is your check engine light on? Have you checked your engine codes? You can go to autozone.com and register for full free online repair manual.

your probably feeling a rough idle of the engine. need a tune up?

in park the engine is not loaded down, just idling at a low rpm=rough
in drive with brake on you have put some load on motor also at low rpm=rough
in drive on the road engine is at higher rpm, = smoother

generally 4 cylinder motors idle a bit rough, especially if one spark plug is not firing right or fouled or one bad spark plug wire. tune up may fix it. if it is not stumbling real bad or stalling then you can live with it.
