The check engine light on my 93 Lexus SC300 has come on recently 3 times. I checked the code and it corresponds to an EGR problem, such as with the vacuum modulator, the EGR valve or the EGR temp sensor. I think these are all near the firewall, driver side, but I am not sure.
Does anyone have a photo?
Would it be best to remove all 3 parts, clean them and stick it all back together?
Any cautions to observe?
Thanks for any help.
