I have a 91 Camry LE with 190k miles. I have had problems with fairly high hydrocarbon levels when taking my emissions testing in the past and I suspect that it is leaking injectors or perhaps poorly spraying injectors. Anyway, with 190k miles on the car, I figure the injectors probably need inspection or, even, replacement.
I checked out how to remove and inspect the injectors in my shop manual and it looks like a pretty difficult procedure. Has anyone ever done this? How difficult was the procedure? Also, there are a number of parts shown in the manual that seem to be required for the testing procedure. Can these parts be obtained from the local parts house or hardware.... or, do I have to get them from Toyota.
I would appreciate any advice about this.
Thanks, Al
