Hello everybody, hope all is well, and everyone's 6G are running strong. Awhile back, I got a check engine light, EGR, so I replaced the VSV, then replaced the modulator, and finally the EGR, drove it for quite awhile excited the light would go off....but it wasnt, had to get my car smogged, so I disconnected the battery for 2 hours and went to get it smogged, I passed the 25mph but failed the 15mph, "probably injectors" I was told, I had already been suspecting the injectors, but was having a hard time getting the right ones since my car is Fed/Canada, and not California. A few days later, check engine light came back on, with egr, I now have a crank shaft sensor code, from the research my friend and I have done it could many different things causing it. Put new injectors in last night, fuel filter and spark plugs, gonna smog it again today. If you guys have any advice to cure this egr problem, I would really appreciate it. The research I've done isn't giving any clear answers. Btw, my friend rebuilt my whole engine, cleaned everything, new gaskets/seals, flywheel, clutch, release bearing, rod bearings, etc...

What are the exact codes and what were the actual passing and failing test results?

That was the first part I replaced, a long with the modulator and the egr itself. I tried to have it smogged again, and I was "borderline passing"...but I had disconnected the battery, gas I didn't let it run long enough before going to smog.
