∙ 12y ago
I had the same problem on my 1997 Toyota Camry. Took it to autozone and they told me the code was ins. air for the EGR, and my EGR was bad and needed to be replaced. i think he wanted like $150, but I'm a college student and it didnt seem to be making my car run really abnormally... i got tired of seeing the check engine light... i took the EGR out, and took all 4 vacuum out with it. i pulled off all the lines and blew/sucked a small puff of air into the bottom of the EGR... the diaphragm moved easily... so my EGR was good. i started to blow through the hoses to check them. when i got to the biggest hose that goes into the bottom of the EGR... it was almost totally blocked. i cleaned it out with a chopstick to break all the hard crap loose... ran hot water through it... let it dry and popped it back in. fixed. i guess i could/should have bought a new vacuum line but it was 3am. :p
