can anyone tell me what to look for when buying new injectors? from afternarket companies?

 

well a couple things that are benefical would be whether or not they are "drop in" style incjectors.....meaning they have the same plugs yours do now and will therefore plug directly into the existing harness....

if not you need to buy the correct plugs

Also the impedance of the injectors.....but whichever you get, high or low, they can both work with the addition or removal of the in line resistors.
