use a multimeter on your 1 and 3 injectors. they should ohm between 12-14 u can also check your coil packs. when you run your car, try pulling out one at a time (requires you to remove the 2 bolts holding each in place). if the car doesn't boggle and return to normal (change in idle), the coil pack may be suspect. if it does, its working correctly. if you come across a suspect, switch the coil pack with a known good one. if the same bad cylinder experiences no change (with the known good coil pack) you may have to check the spark plug for that cylinder (as well as injector). If you get a boggle in the bad cylinder and it returns to normal, and the issue moved to the known good cylinder (now has suspect coil pack) u have a bad coil pack and need to have it replaced
