Okay so I am new to the rx7 community but I have gained an interest. I am thinking about buying a 1988 RX7 GXL and when I asked if there were any issues. The seller told me that it has trouble revving past 4k when driving but does fine in neutral or park. He said all it needs are new plugs and injectors which he has on hand but hasn't installed them. Does this sound accurate because if so I would be a buyer if I can get the car for a decent price.

 

Try searching the second gen section.

Here is one I did on the issue.

The FC is known to have a hesitation around 3800 rpm due to bad ecu grounding. AaronCake has an article that explains repairs in depth here, nothing too bad if that's the issue: https://www.aaroncake.net/RX-7/grounding.htm
Bad (specifically leaky) injectors usually lead to flooding, so I'd look for that as a symptom if the previous owner suspects something wrong with fuel delivery. I'm sure you know this, but definitely take it for a drive if possible after reading up on some of the common issues to look for when buying a S4 FC, I believe AaronCake has another article on this too that I used when buying mine. Good luck!

 

If it’s so simple and he’s so sure that’s all there is to the issue, tell him to install them and call you back when it’s running right. You’re not familiar with the engine or platform. Why do you want to buy someone else’s problem?

 

100% agree. Typical story. There's always something "so simple" and the parts are on hand, but it never adds up. He's the expert (in this case), not you. It's not a hard job, so let him put his money where his mouth is.
