EGR system... complicated?
Hmmm ...EGR system <--> engine light relationship.
Got a CEL (believe it was 401 - EGR Insufficient Flow) !!!
Google.group on auto.camry
Some advices from the article posting:
(1) DON'T waste money (and time) on "guaranteed" cleaning treatments.
There are no magic elixers. A clogged EGR and other significant
deficiencies will NOT be helped by these. Premium gas will not help
very much (my 86 passed the retest with a quarter tank of 5 month old
regular gas).
(2) If you can't do it yourself, take the car to an independent
mechanic (preferably one familiar with Toyotas) and ask him to remove
the EGR and steel tube that runs to the manifold. Mine was 80%
clogged, but very easy to clean. Should take 1.5 hours max. for a
pro; the only problem is access through all kinds of cables and hoses.
(3) At the age of this car, cleaning the throttle body is probably a
good idea. I was shocked at how much gunk was in my entire intake
system.
(4) DON'T replace the convertor (or oxygen sensor) without a good
reason to do so. It may help you get past testing, but you can mask
the real problem(s) and still suffer poor performance/low MPG
afterward.
