Hey I have a 98 k1500 5.7l vortec and yesterday I was on my way home from work and my service engine light came on. Everything seemed fine after but the light was still on. Today I checked it and it was a cylinder 4 misfire. On my way home the light turned off until my way home tonight. This time the engine kinda rumbled when on gas and it didn't accelerate, stayed at 2000 rpms, so I let off gas. I tried again n did same thing then the light came on. After that it drove fine. Any suggestions?
