MAZDA 6 COMPRESSION PROBLEM

2005 Mazda 6 • 75,000 miles

MY MAZDA 6 MPS 2.3 TURBO RUNS FINE. WHEN ITS NOT MOVING YOU CAN PUT YOUR FOOT HARD DOWN WITHOUT A FLUTTER BUT WHEN YOU ACCELERATE HARD UNDER LOAD (MOVING) IT MISFIRES VERY BAD. COMPRESSION IS ABOUT 173 ON ALL FOUR, NMAZDA HAVENT A CLUE, DIAGNOSTICS JUST SAYS MULTIPLE RANDOM MISFIRE. CAN YOU HELP. PLUGS CHANGED

Use the scan tool to monitor the MAF, TPS and check the fuel pressure.
