I got some time today to work on my z, and here's what happened.
I hooked up my scanner tools and tried to start the car. It did exactly the same thing, it would crank over, fire and die.
No codes were showing, the first picture is what the scanner was reading. The iac position was reading 150 steps and the desired idle speed is 3187.5 rpm. I tried to start it a few times but it started to smell like un-burned fuel and I did not want to back fire the car and damage something.
I went back in my house to check if the iac position was right. I went back to my car about 10min later and tried again.
This time it started but was misfiring bad, but kept running. I snapped the 2nd photo when that was happening. No check engine light.
It settled down and idled fine. Sounded good. I reved it a few times and it responded like it should. Sounded good and was acting like it wanted to go for a drive. I snapped the 3rd photo during that.
What do you all think? Is my iac sticking and causing it to not start? It never threw a check engine light the whole time. Should I replace the iac?
Thanks in advance.
