So I was out one weekend driving around and an evo came up on me, so we did some pulls and on the last one when I shifted from 4th to 5th my car seemed to not move it was weird. Then I noticed my car shacking and my rpms were at 0, so I rev'd and the car came up. I got it home having to hold the gas the whole time so the car wouldn't die. My buddy thought it could be a vacuum hose might have got blown off, so I took the IC off and looked at all of the hoses I could see and they all seem to be okay. I can start the car but it sounds like its sick. And like I said dies if I let off the gas. I am waiting for a jack to get under the car to look at the turbo and make sure everything around that looks to be in working order. The only other thing I can think to do is do a compression test and make sure I didn't blow a seal. And thing you guys can think of will be a life safer. My car is an 89 Rx-7 TII, stock turbo, racing beat exhaust. Thank you.

Sounds like a vacuum leak. A visual inspection doesn't hold any validity. You need to pressure test or smoke test.

And check for error codes. Car might be limp mode among other things.

Check your TPS!!! mine had an issue very similar to this, I found out by coincidence that it was my tps and when i fixed it everything was kosher again.

I would be checking again for vacuum leak IF it ran great until the very moment you rolled hard on the throttle. At that point you could have easily created a vacuum issue.

Sounds like you blew it up to me. I think you forgot to mention the hard misfire at full boost.

I think it is a vacuum leak my buddy had a leak on his car as well, found the hose put it back to where it goes and it was all good the next start.

Thanks for all the advice, I checked every single vacuum line I could think of and found nothing. I took my turbo off and found the bearings are done. I spin the blades and they don't spin freely. So I am getting the turbo upgrade from rotor sports racing.

The engine should still idle with the turbo bearings being bad i believe, i'm not a turbo guy so don't hold me to it

Check your compression before you spend any other money. Compression checkers are 20 bucks at O'Reilly. Don't say I didn't tell you so.

Your problem is a vacuum leak.

i would check for vacuum leaks first. Easy fix if it is. ZIPTIES!!!

POP Goes the weasel...sounds like you ate an apex seal

do a compression test the rotary way (3 bumps on the needle per rotation per a rotor) do a search, lots of info on compression testing rotaries with a standard compression tester

It is not the most accurate results but will show a dead rotor

watch the vid-

I already said that but im just a dumbass.
