I have 89 Iroc 5.7and to sum tings up I have had everything done except having the fuel injectors changed. After awhile of driving when u come to a stop the car will either die or sputter and catch itself and I need some cause I don't know what's wrong

 

More than likely you have one or more bad injectors. Use a multimeter and test for ohms. Test each injector with the key on and engine off. Just put the probes of the multimeter into the top of each injector where the two wires go into each one. You should end up with something like 0.013 to 0.018 or so with each one. If you get to one that is like 0.003 , it is bad. If you replaced everything else then you prob have a bad injector.

 

oh and you should replace all of them at the same time,not just the bad one.

 

ok thanks i will post after i check them
