Is this injectors bad?

Hey
Have a idle problem and have chance the IAC and TPS but it still idles bad.
Today i did ohm out the injectors and have 2 at 8-9 ohm and 4 at 12 ohm and 2 to at 16 ohm is this the problem or ?
I have no vaccum leak
Then the car is cold it idles okay but when its gets hot the idle goes up and Down

Thanks Claus

Hi Claus ,

Yes , you have bad injectors . When you mention a couple at 8 ohms and a couple at 16 ohms , that's all the proof that's needed . There is a TGO sponsor company called "South Bay Injectors" that you should check with for replacements . This company is highly regarded here at TGO and will do you justice on a set .

PS , that's quite a range of ohms readings , 50% is far outside of any acceptable tolerance for anything that should match as close as possible ..

Mine are also noisy. But they work fantastic. Just close the hood and move along!

Enjoy!
