Throttle Body Removal Question

[MNJack]

Service manual says drain engine coolant before removing throttle body. Haynes manual says plug the hoses to prevent coolant leakage. How much coolant is going to leak out if I don't drain the engine coolant? I started to remove one of the bypass hoses and coolant started leaking out and I didn't have a good method of plugging it, so I was just wondering how much of a mess I am going to make if I don't drain the coolant. I would guess I would only need to drain 1/4 to 1/2 anyway.

Several cups.

Just take a piece woth something shoved in the end & put that on each line. You can also bypass it forever & put a hose connecting the two.

Define "mess".

I did mine a short while back. Engine was cold & very little (less than an ounce) actually came out. But plugging the line as mentioned above should eliminate much of a "mess".

Well, I kinda chickened out, and stopped short of removing the throttle body. However, I did give it a good cleaning. There was lots of black carbon on the plate and inside. I will take another crack at the IAC Valve some other time. I actually solved a problem I had been having! From a dead stop (at a stop sign or red light) it had become very difficult to accelerate smoothly. The gas pedal would seemingly stick slightly, and when more pressure was applied it would unstick and the car would lurch forward. I got in the habit of tapping the gas pedal lightly to get the car going. I tried lubing the throttle linkage to no avail. Well, apparently it was the throttle body plate that was sticking. After cleaning it all up, no more sticking.

The other problem I am having is sometimes I get the stalling on a warm startup. I very rarely do a warm startup so it doesn't happen very often. I do want to clean that IACV tho.
