Engine running rough--Fixed

[Grandma91quis]

Ive been trying to figure out why my car has been running crappy. Its running smooth now. I went through and checked all my vacum lines. Did a full tune up this summer. Changed the head gaskets and every gasket from there up. The whole top end of the motor was cleaned and inspected. Changed the fuel filter. Checked all the injectors. Theres probably more but thats the basics.

Here's how I got it to run smooth. My friend said he saw someone do this with there drift car to get another season out of it. You take off a vacum line that goes to the intake. I used my brake booster vacum line. Get about a half gallon of warm water. Start the engine it may idle high if the vacum line is off, so you may want to wait to pull it out. After you have the engine running take the vacum line off of the brake booster. And put the vacum line at the suface of the water so it sucks a tiny bit at a time. Be careful and dont let it suck to much water in. Once your done let the engine run a few minuates 2-3, rev it a few times, and cut it off. And you will have alot of nasty s**t dripping from your exhaust. I fixed my problem if your stuck try this. My car seems to be running alot better. No more hicups or missing.

Pretty much an intake cleaning. Works wonders. Can do it with carb cleaner or intake cleaner also, or seafoam.

We actually use that procedure at our shop when we have a car that fails an emission test. Works wonders, I cant believe the shitboxes that we've made pass by running a litre of water through the intake. Huge differences in the numbers before and after. I do it to my car about once every 6 months. It is the same thing as using a carbon cleaning chemical, cept the chemicals dont hang around afterwards so you can run the emissions test immediatly after.

Essentially steam cleaning the intake. Very important to not let it eat too much water though. Hydrolocking an engine isn't pretty. I've seen the ceramic insulators fire right out of the plugs, and the valves pushed right into thier seats from cylinders filling with water while the engine was running.

I was thinking just the same thing if it was safe but I guess it is
