here is my problem....my car starts fine but when im driving it and go to down shift and step on the brakes it wants to stall and when it does stall it wont start again until i unplug injectors burn excess fuel out then plug them in while its sputtering then it runs fine...any help would be appreciated...i think it might be idle air motor...all vaccuum line are brand new...no vac leaks

 

If you have to unplug the injectors, that should tell you something.

 

ecu, injectors, fpr etc.
