ZZ4 Crate Motor maintence

Afternoon 3rd Gen's So if anyone has a gm zz4 crate motor and are having problems with the idling, or having your car just stall out. Here are a few tips on what it could be.

I just had to spend 900 on new stuff for my motor, I had to get a new chip, New fuel injectors, and a new Fuel stabilizer. Now my motor is running a 100% bette there is no shaking or stalling going on and I just hit the 3,200 mile mark on the engine.

the issue was most likely the injectors, the rest is just money out of your pocket
