85 Toyota surging and throttle problems (help?)

[Mark m.]

Air bubble in cooling system

 

[codey4122]

My water temp sensor was unplugged and that took care of the surging along with a diff tps . I am wondering if the tps I am using is causing it to do the bog cause with my bad tps it does the surging but it let me rev it up. How could I get the air bubble out if thats what it is? I havent checked the valves yet. Ive checked the plugs they are burning just rightand ive changed the tps. and I have checked all sensors I got it to idle good now it just Boggs:/

did you adjust the tps or just throw a new one on there? just being a little bit out of spec on them and it will cause all kinds of problems.

Air in the cooling system will cause idle surge but not really the bogging. Is your MAF plugged in good?

 

[codey4122]

I have tried to adjust the tps all over the place and I havent really checked the maf I will do that next!

If you missed getting the tps tangs on the correct side of the throttle shaft ears, it will do exactly as you are describing...:awesomework:

Okay so now it says when I try to rev it up the codes come back and it says

its code 7 and 12 whichis either tps or knck sensor could the knock sensor cause this bogging?
