Hey all,

 

My '87 GL failed its emission test today.  Hydrocarbons were more than
double the max and CO was about 1.25 times the max.  My muffler, cat,
and O2 sensor all have less than 1000 miles on them.  Engine is original
2.1 w/ 159K and about 20K on the heads.  I only drive the van every
couple weeks and on extended weekend trips.  Thoughts?  Advice?  

 

Thanks,

Andrew
