I'm currently working on a '91 S10 2whl. drive w/a 4.3.Complete tune up,rebuilt throttlebody and new injectors yet it still has cold start irradic idle and dies till it warms up,any idea how i can rectify this problem?I suspect maybe the EGR valve or even dead cell in battery because of low reading on amp guage

Thanks for the helpful advice. I hope you constantly write lots of great posts in the future.
