Before i bought my RX7 i stubled across a place that told a bunch of ways that could fix the 3k stumble. Well now that i bought it, it has the stumble very bad. I've used the search function and i cannot find it at all again. Could someone please send me a link to it or post it here. Thanks, Russell

 

buy a power fc.... no more stumble

 

I did, and it is sitting right here in my living room waiting for the rain to stop so i can install it. I wasn't aware that it was a fix to the stumble problem. I guess i will give it a try. I still would like to know about the list of things that can be done to fix it. The only thing i remember is adding more grounding straps to the engine......Russell

 

Use "hesitation" as a keyword in search. There will be LOTS of posts on the subject.

 

PFC will fix. I don't think you can fix the 3k prob with simple fix its. Much easier and probably less expensive and time consuming to just install the PFC.
