My 84 toyota supra-185K miles-good shape----but wont pass smog this year
i am sad ----it would be sad if I have to scrape it?--
replaced O2 sens-cat5 conv---reamed out blocked pipe back of EGR ----and the NO #s actually got worse at 15mph --up to 1181 from 1139----the 25mph went down to 1238 -from 1291
i have spent my 450$ and know I can go to ref for 1 year pass=lots of red tape etc
and still I wont have a correctly running engine!
which I would prefer!
the used parts pirates want $1000 for the EGR valves-2 port-which I may pay if I knew that would be the last of it----but someone else looked at it and said there may be blockage from engine manifold to the EGR valve that is the problem
how can I be sure? And do I have to go to japan to find a replacement part at a fair price?
can you help me save this auto and make it right?
