Okay I have a 94 fd rx7 with a turbo back exhaust and power fc stock twins stock fuel. While driving to work car went from normal to sounding like a chopper with no power like a switch got flipped. So got it home figuring the engine blew up. Car starts up easy holds idle just sounds like a Subaru and zero power. So figured Id compression check it and give myself a reason to finally get a rebuild and go single. so stated the car up let it get to operating temps, shut it off pulled the trailing plugs pulled the egi fuse held throttle open did the rear first got 97-100-101 front got 180-182-178. Both these numbers was corrected at alt and rpm on the RCT v5.2. The front rotor confused me so I did them both again and got almost exactly the same numbers. So I took a few days searching and couldn't find anything related the the type of numbers I had on the front rotor being so high. So I figured id check my ignition system while I kept searching for an answer on here and found the ignition Harness had a Broken ground fixed that continuity checked the rest the harness checked out fine got everything back checked for spark everything seemed fine. Soo started it back up seemed like it help my idle seem more steady but still sounded like a chopper and no power. I also replaced the spark plugs at this time and checked the ohms on the plug wires and they checked out good. I was starting to wonder if I had a fuel injector issue but the high compression numbers on the front are confusing me. Any advice on why the front was reading so high and any ideas on the issues with the weird idle and lack of power. Front rotor Rear rotor

I would contact Steve the person that makes the compression tester. I've never seen compression that high before. The most I've ever seen was 125psi in a 13b REW.
Thank you I just sent him an email about the issue Ill see what he says and I'll update. I'm baffled at this point I started it up last night just thinking maybe I did something wrong and I got the same results.
