I have a 98 Honda Accord, automatic, with a 3.0 VTEC engine with 189,350 miles. It was diagnosed with cod P0401: EGR insufficient flow detected.
I was told and apparently in the instructions it states the following to repair/fix the problem: Unplug the EGR Port in the Intake, remove upper portion of Intake Manifold, drill EGR port, install Sleeve and replace EGR Valve. Instructions also indicated I need a EGR Pipe kit: 06175 P8L-A00 which contains a special tool to drill manifold and install Sleeve: Kit 07ZAO-P8AA000.
Has anyone done this type of work on a 1998 Honda Accord, automatic with a 3.0 VTEC engine. I would appreciate your feed back. Is this a easy job? I’m also confused about needing the special tool (I believe it’s a drill bit) and drilling the port. Are either one of these two Kits I mentioned really needed? What do you recommend I use to clean the port? I thought I could just clean the port (hole) and replace the manifold gasket.
