Failed Smaog, Possible EGR problem
So I have a 1988 Honda Accord that justfailed smog,it failed the emissions test. Anyone else have this issue, any insight on what it might be, thinking maybe the EGR. Any input would be awesome... Thanks in advance

RE: Failed Smaog, Possible EGR problem
On many Accords, the EGR ports where EG is injected into intake manifold become clogged leading to CEL and code for EGR low flow. Is there any DTC code set?
Is this acarb or FI engine?
Lack of EGR flow will cause high NOX and failed emission test. Cause can bebroken vacuum line,failed vacuum switching solenoid orthermovalve, failed EGR valve, blocked EGR ports/passages. You will need to get a manual for your car and follow diagnostics.
good luck
