Another new guy to the rotary scene looking for some help. I have 93 R1 single turbo with all the goodies that go with the conversion. My problem is that one day I was sleeping my brother decided to take my car for a drive and filled it with 87 octane fuel. Needless to say my car was running like crap. It was only driven a few miles and not hard. I drained the fuel out but it still runs terrible. Previously ran fine until this incident. When idleing it jumps back and forth between 1000 and 1500 rpms a few times and then dies out completely. It restarts no problem but does the same thing. When I rev the engine it just doesn't seem to have the same grunt. I was hoping one of you could give me some direction to start my trouble shooting. Any suggestions would be greatly appreciated!!

How much vacuum does it have? It sounds like your brother did more that put cheap gas in it.

Get a compression check on the engine...

Do you think in that little bit of time it could of toasted the engine?

rynberg

Yep.

Yes, I think your brother blew your motor.

I just started it, with me keeping rpm's around 1500 vacum is around 10. When I left off of the throttle vacum would go to 0 shake a bit and die out. There was also a lot of smoke from the exhaust.

Just get a compression test done first. If the compression check out fine, then you can troubleshoot other areas.
