greekguy7 Posted May 23, 2006 Report Posted May 23, 2006 I been trying to figure out a problem with my car for a while now, replacing a couple sensors along the way unsuccessfully. It would sometimes stall at idle or upon deceleration and I kinda lived with it. It goes worse though, when it to started to stumble and hesitate real badly upon acceleration and would also not restart when hot. I pulled the plenum, ohm'ed out the injectors and found one at 11.1 ohms and another two injectors at 9.5 ohms. I believe the spec is 12.1 ohms. I replaced all 3 and the car runs fantastic! Perhaps I had one injector out of spec for a while causing my intermittent problems too. As long as you feel comfortable pulling the plenum, its an easy test to do before replacing a dozen parts along the way trying to track down a drivability problem. Thanks for all your help along the way! Quote
SigEpCutlass Posted May 23, 2006 Report Posted May 23, 2006 Well, in our cars I know many people have had to replace their injectors for some reason or another. Glad you have your problem fixed. Quote
GnatGoSplat Posted May 23, 2006 Report Posted May 23, 2006 It's good that those injectors were bad since you pulled the plenum anyway, but you don't have to pull the plenum just to test. There are 2 you can test, the other 4 you can test by unplugging the ECM, unplugging the 2 injectors you can get to, then measure each bank. You can then calculate average resistance of the 2 remaining injectors in each bank using Ohm's Law. I had a writeup with pics for this... somewhere. Quote
