car having hard time going past 3k rpm and overheated
hi im new to the forum and need some help here, i just got my 86 rx7 fc na 2 weeks ago and started loving it, but problems just kept comming up, and right now i have a major problem
its having a bad time starting, it wont go past 3rpm it sputters i think and just vibrates, so i parked it kept the engine on tried pressing the gas once in a while to see if its good to go, so it made it past 3rpm in idle for 10minutes staying on the side, i drove it back home which was just about 5 minutes away to where i was parked, and i just noticed water temp was at 220 and just rised a little while making it closer to home, then right when i parked it it got to about 240, and steam came out of the hose that connects to the radiator,
when i got it i drove it home which was a 2 hour drive and made it back perfectly with a temp of about 160-180, and after 2 weeks of using it as my dd it never had any problems till last night, wont go above 3rpm

Check your grounds:

Make sure the pressure/boost sensor is plugged in (passenger shock tower).
Don't overheat the engine like that. You can easily damage the water o-rings, requiring a rebuild.
Check your cooling system as well:
