I need to share some amazing info to everyone in HAN world - I recently purchased some injector/engine cleaner from a local store - it's called SEAFOAM.... let me tell you, this stuff really works! :bowdown: Some tech from a local garage told me about this stuff that it eats carbon like mad, but won't wash out your rings and seals like the Techron or honda stuff. So I put it to the test - I pulled all the plugs out of my engine and put about 10ccs in each cylinder, then I let it sit for a few hours - the rest of the can went in the tank. (BTW this stuff is even safe for the crankcase too!) Well, after I put the plugs back in and fired the motor back up, a got a big surprise..... after the smoke cleared from all this stuff burning out of the cylinders, it instantly ran a lot smoother! (and no, it won't hurt your O2 sensor) I took it down the road... the throttle response was a lot better as well as the idle. This fixed the problem I had with the low engine idle! Out of curiousity I pulled the plugs back out and look down on top of the pistons - the carbon really cleaned up well! I also fixed an older accord that smoked really bad with this stuff - I put it in the oil and it might have unstuck the oil control rings... no more smoke. The engine went from burning a quart of oil in 500 miles to a qt in 2500! Just when I thought it might be just another piece of crap additive like Marver Mystery Oil.... was I wrong!
