I finaly was able to get some water down the throttle body of my engine yesterday.

Let's say first that I cured about half of my idle roughness by replacing the positive battery cable (found out the battery end was much corroded when I replaced my starter).

The water treatment seemed to improve things a little bit more and maybe most of you would be happy with my engine's idle but I remember I had silk smooth idle not so long ago and I'm trying to regain that.

I removed the small vac hose that's just upstream of the throttle plate and replaced with a same diameter hose (the other end of the original hose is a bear to remove and replace). I then proceeded to suck from a small glass jar a few onces of water at a time. Maybe I was too timid and will try again shortly with greater quantities of water.

Nothing black came out of the exhaust, puffy white vapour right from the strart. Does it mean there was no carbon to speak of ?

Also, since the free circulation of electricity seems to be a factor, I will shortly clean every ground I will find.

Oh yes, I almost forgot: right after the water treatment a small hesitation I had at slow speed (when i accelerated llightly in second or third at slow speed), the kind that rocks you lightly back and forth, was completely gone.

And finaly, if i tried water it's because two previous applications of seafoam did nothing for my idle roughness.

We used wtaer before that fancy chemical stuff (or Marvel Mystery Oil).

Not being black is good. Being gray is better means that some carbon came out. White means no carbon left and you steam cleaned the plugs and the valves. All good. It doesnt take much water. remeber that steam is 15,000 psi at many many many degrees (lets just say its measured in kelvin with 4 digits) to clean things out.

I found that I would not see any black until I had sipped down a significant amount of water.

Thanks virrdog, good info. I was under the impression that the smoke was supposed to go from black to puffy white. Good to know it's the reverse. I will then certainly go at it again soon.
