Hey guys, 2001 V8 w/ 112,000 mi. This summer I replaced 4 injectors to fix the leaky injector/hard start problem. That worked till last month and it started doing it again. So I replaced the last 4 this weekend. It starts perfect now, but after driving for a bit, once the engine got up to temperature, it started to shudder when I hit the gas. Idling in drive, the engine shudders and hesitates like its misfiring. No engine light coming on, I went to autozone and they hooked thier handheld up to it and gave me the idle air control sensor code. Replaced that, fixed nothing. Is it possible one of the injectors were bad? Do injectors "kinda" work? Or are they working or not working type of things? How would I know if it was a bad coil? Like I said, no check engine light. Please help.
