A couple of weeks ago my RX7 started to hestitate mildly on light acceleration. This problem has got progressivley worse until now it almost puts you through the windscreen! The car idles perfectly and the problem is not evident under full throttle. There doesn't appear to be any particular rev range and the car runs perfectly first thing in the morning when it's stone cold..... as soon as it starts to come up to operating temperature the problem persists!

Any help on this matter would be gratefully appreciated.

 

This may be known as the 3k hesitation...I'm gonna have rotary power go through my damn car and repair it

 

You need to replace your O2 sensor, if not, check your TPS.

 

Change your plugs while your at it.

 

If someone figures it out, let me know. I have the same problem. I've fixed every ground and added several. Not the plugs. Could be the TPS I've not checked that. Only other ground I've not fixed is the fuel injection under the intake. I've heard from 1 person that this fixed the problem. I've also not sent the injectors to be cleaned. I still think it's the FI ground. I know, I know, buy a PFC and it'll fix it...

 

Yeah, the same thing happened to my TII and it turned out to be the O2 sensor.
