Rx7 fd3s idle pulsing 1992
So I just bought a Mazda rx7 1992 fd3s. The idle on it pulses between 1000-1500. It'll do it for 4 or 5 revs then it'll stop and go back down to 900/1000rpms. I was wondering what could cause this and how to fix it. I've read the tps. I was wondering if anyone knows how to check it and if that could be it. Also if I took it off would I need to replace any seals. Let me know your input. I was gonna post vids but it won't let me. Any help will help a ton! Thank you!

Follow these instructions and you should come to a more accurate conclusion of your problem. Either your TPS is bad or you need to adjust it.
