My car has the exact same symptoms your car had. Any idea on how to unclog the egr lines? I don't feel like paying $98/hr. to get this fixed by toyota.sleeper said:
All 3 lights lit up when I got on the highway, thought I fixed the problem when I found a badly cracked vac. cap to a TRAC control related part. Reset the ECU, but once again the 3 lights came on. I noticed that if you drive in city traffic the lights never come on but once I get on the highway, not even a couple of minutes and all 3 light would come on. This was repeatable, reset ECU, drive in city traffic OK, go on highway and instant Christmas lights.
