My a/c stopped working. a/c coil bad. replaced w new coil, new pulley w bearing, new clutch plate w (old) spaces, new a/c stretch belt.
drove it about 5 miles, a/c stopped working. Clutch plate turned intermittent. installed (new) spacers which were thinner than old ones. heard noise when a/c turned on. replaced spacers again ( one new, one old) noise stopped, clutch engaged. let a/c run for 20 minutes, but a/c clutch and compressor stays on continuously....afraid pressure will continue building up and rupture a/c hose.

My Mazda takes a while to pick up speed if I try to hit the gas to go fast the rpm revs up. My clutch goes in to gear just fine it just takes time to pick up speed. And on an incline its worse. The rpms just rev up.

Still idling ruff. Can't get a code to check engine codes. The car ran good until the battery died. What can I do to fix it?

When I drive over a speed hump, even very slowly, or just small bumps, I get a strong groaning noise when the car rises and settles. When on smooth roads, no problem. The car is a 2009 Mazda 3 with 38,000 miles. All service has been through the dealer.
