Problem 1 sounds like maybe a TPS issue what does your tps voltage read when this happens? Does voltage rise and fall normally? Problem 2 needs a gasket and clean the surface til you can eat off it, and make sure the housing isn't cracked.
Revs Stick and Thermostat Leaks
OK well its the usually scenario, I just bought a 240 and there are problems. I don't mind them however as I knew this car would be a project.
Anyway, here's the deal, whenever I rev the engine it revs up and then the rpms stay at whatever it was accelerated to for about 3 seconds and then they drop back down again. Sometimes they even climb 200 rpms or so and then stay there 3-4 secs, then drop down again. I've searched around and I have some suspicions, and I'm working on those, but I just wanted to hear what you guys have to say. I cleaned the throttle body so that's not it.
Problem 2, I replaced my thermostat and used high temp rtv to seal it with no gasket. And it leaks right at the connection where you put the thermostat in. I did this 3 times thinking that I just sucked at it, or did it wrong but I think that one of those times I should have gotten it right. Do I need the gasket that the Chilton's manual says I should have? I didn't take a gasket off when I removed it the first time.
And I have been using the search function.
The short version
Rpms stick for 3 seconds, and even climb 200
Thermostat leaks at the connection point - gasket necessary?

I'll measure voltage and report back. What would you consider the normal rise and fall rate of voltage to be? Just a steady rate of rising when you hit the throttle and falling fast proportionately?
Ordered a gasket, should be here in 2 days (so says O'reilly), and I'll sand those surfaces with 400 or 1000 grit till they shine and check the housing first probably.
Thank you!
