So here it goes:
Failed 1 out of 4 emissions tests here in my state. The one I failed, they hold the car at 2500 rpms, and I was uber rich.
Symptoms:
When I shut the car off, and restart it, it will have a hesitation (usually starting right at 2500 rpms) up through approx. 3200 rpms. This hesitation remains until I drive for a little while, and it happens whether the car is started up warm, or ice cold.
A couple weeks ago, cylinder #1 wasn't firing (car was running lean and VERY rough). I replaced the battery, cleaned the injector connection AGAIN, and now I have my current situation. At least it's not running lean and shitty anymore, but now I need to pass emissions.
I also changed the fuel filter, oil, etc.... the basics.
Basically my question is: are there any other things I should check besides the injectors and/or the MAS? I want to get this squared away soon, before I do other things to my Z.
THANKS!!!!!!
Car now has 115k on it.
