There are four shops at play here
shop 1: doesn’t do smog just repairs, they found the egr vacuum hose fixed for free they did the ac too.
shop 2: smog only he did the retest for free and told me to drive it around.
shop 3: sent it out to be smogged at another shop, two years ago, they had to adjust the timing that was it. I have a feeling they crossed something.
I replaced the air pump about 4 years ago
egr was also replaced.
im thinking it’s a bad injector or a vacuum issue.
