rough idle, running rich

hmm what about engine dying when blocking that port?
Jay said or read it on another thread that it should not lower idle when it is block off when engine is warm
could be the stat has simply become stuck, in closed position, with a small leak to the open position? when was it or the throttle body itself last cleaned?
 
Hmm you have a point, I don’t think it has been cleaned before, any tips of how and with what to do so?
ofcourse. remove the entire Throttle body from the car,
grab yourself a toothbrush or similar implement, along with some degreaser, and go ham. Q tips work well for cleaning the vac ports, just be careful not to get it stuck in there :)

Would hazard a guess your valve is the issue if the book is to be believed.

pro tip. the waxstat gasket has no part number. so dont mess with it too much. or its cerealbox gasket time for you.

Cleaned the waxstat throughly, didn’t unscrew from throttle body though, but still no luck. There was gunk inside the coolant pipes but managed to remove it. Now when I block the port, the engine still dies. I guess waxstat is no good phhff.. any more help

how to know if a waxstat is good before purchasing..?

i'm getting throttle body from an auto 4efte. Is it the same as the manual one? I just need to swap to my tps. The assembly is the same right? Any opinions
Also will try to change my thermostat to see if that makes any changes

TPS on an auto is different, it's not just an on/off signal.

Can't remember if you can just swap the manual TPS across, will have a look at the weekend.

okay so I need to get some confirmation on some stuff
The 2 coolant ports on the waxstat, are they suppose to be free flow, meaning for example if I blow air in one port, it should come out the other? or should they hve no connection? same for the 2 vaccuum ports
