Hi all, I have just hit a severe dilemer with my 1994 Series 6 RX7. After having a recent service changing plugs, oil filter and oil, I had to replace my clutch. After doing this, my car returned to the road going fantastically. However, a week later it started to have a severe miss at higher revs. It has now got to the point where I am not feeling the second turbo come on, I am peaking at about 0.5bar boost pressure and it generally runs like a bag of ****. I have removed the plugs and checked these, they looked o.k. I have remove every possible hose/intercooler/turbo piping and everything seems o.k. Could it be an O2 Sensor problem or even a temp sensor problem???? Help, I am running out of ideas fast!!!

 

does it only cut out under lots of boost or cut out regardless of what boost you are making?

 

It seems to be only when the second turbo is starting to produce boost that it goes funny. I can still feel the first turbo come onto boost, and then the second one just doesn't follow. Then once into high rev's the miss begins!
