I'm currently looking at a fc turbo 2 parked for 6 years due to a electrical peoblem. Im getting more information on it via email and depending on what common problem fits may make or break the deal. Im an auto tech so im atleast good with electronics. The car is over 3 hours away and i dont want to truck up there blind.

 

Ok i know double posting isnt very accepted. The one im looking at when it was run last before it was parked. When it warms up it would sputter at idle. And thats why it was parked. My thoughts are a bad o2 sensor sending bad signals after closed loop. Possibly bad spark plugs or timing. Atleast thats what i would look at first if it was my pickup. Anyone else have a similer problem? Solutions? Is this a common problem. Input would be helpful before this one gets sold from under me.

 

I am having a similar issue, car I bought sat for 3 years and I got it to the house, deleted emissions, re set timing, took out the rats nest and new plugs, wires, filter and it starts, idles, and runs great until it sees closed loop then it falls on its face, just a heads up I have not figured what it is yet.

 

Here is something I figured out that might help Proper RX-7 Grounding Procedures
