No Vacuum in EGR valve #16 hose
Hi All....
I have a little problem with my 1993 Honda Accord EGR system. The car has 171K miles. The Engine runs fine at idle except for a slight, inconsistant miss. Then the car has a slight hesitiation at about 1500-1800 RPM. Other than that, the car runs fine. I checked the hose (#16) that goes to the EGR value and I determined that it has NO vacuum in it (at idle or above 2000RPM). What would cause NO vacuum to the line to the EGR valve? A previous post said it might be the EGR solenoid. How can I tell if the EGR solenoid is faulty? I will admit to knowing very little about Hondas, but I really want to learn. Can someone please offer me advice to fix this problem? Hondas are great cars and I would like to keep this one running for a long time :-) |

No Vacuum in EGR valve #16 hose
Thanks for the reply Jim. Do I just have to clean the EGR valve?
Or, do I also have to clean the EGR passages under the brass plugs? Also, if I have to clean the EGT passages, how do you take out the plugs?? There is no way to grip them in order to take them out. Seems like the only way to remove them is to drill them out. Am I correct?? Thanks again!!! |

Idle problems would be caused by an open EGR, either one that is
clogged or getting vacuum at all times. |

DO NOT try to drill the whole plug in one go - unless you have a source of bigger plugs. |
