Today I cleaned the throttle body with a bottle of carborator. I also removed and cleaned the front of the sensor which has the idle speed adjusting screw on it.

But when I took it to a test drive, some smoke came out of the hood. And I found out the coolant begins to leak fast from a hose.

What could cause this? What should I do now? Did I put the sensor back in a wrong way? I noticed it has a hexagon tip.

THanks.

 

You put a hole in something = coolant leak
cleaning solvent is burning off = smoke


Just a guess. There is almost no way to tell you the problem over the web. Next time, use a real throttle body cleaner.

 

I've never seen that at the local kragen. who makes it?

I've seen several brands at PepBoys, the stuff I used was called "air intake cleaner"

 

Does the three step intake cleaner that they do at Valvoline include a throttle body cleaner?
