Recently I ran about half a can of Seafoam through my egr port because Honda h22's are widely known to have them carb up. The hesitation I experienced before is completely gone now, but now I keep throwing random misfire cel's in multiple cyl's. I was already at about 1qt/1,500miles, but after the seafoam: I had a
"OKay guys, its official. The problem on my Prelude AND Accord fixed.
I just did this this morning, and I just drove the Lude for an hour trying to get it to bogg, but it wouldnt.
This is what I did
Remove coil and EGR Dump little more than 1/2 bottle of seafoam engine cleaner in EGR ports.
Most of it in the right side port closest to motor, little bit in the other one.
The dump the rest of the seafoam into a cup big enough to soak the bottom of the EGR valve in and let it sit. I used a tooth brush on the bottom of the egr to loosen up the real bad stuff. The replace the egr.
Let that #@$%! soak about 10-15 more minutes.
now I did this to prevent problems, prolly not needed. I pulled the plugs out and the ecu fuse and cranked the motor 10 or so times to get rid of excess. I dont think this step did anything, but I guess its how much seafoam you are going to be using.
Start up your car, be gentle for the first 5 minutes of driving, then hammer on the gas a couple times to redline.
I noticed it took about 10 minutes to rid the car of all the smoke, but now its so smooth, my car has no 2500 to 3k bog anymore.
and dont be fooled, I had no check engine light ever on my car. go figure.
