I own a 2000 Miata with Adaptronic ECU managing a JDM NB8 Engine. Engine is equipped with GT2560R turbo , 600cc detchwerk injectors and LC-1 wide band sensor. I do have somewhat of a violent jerk when I start the car (cold), once it warms up it does restarts ok. It does start fairly quick too, but with the violent jerk. Has anyone dealt with this problem? Any ideas, solutions or comments?

Note:

Please go somewhere else if you have no intentions of providing info or help. Im really tired of having to deal with your ******* abilities.

 

This is a good example of how not to ask for help. You don't ask for help and then insult the people who might be able to help you. Dumbass!

 

What condition are your motor mounts in moron?

 

Take the nudie pics that are taped to your dash off. Maybe a little more cranking pw? Try it. If it doesn't work, I was wrong, but that fixed it on my car.
