My name is Agustin. I live in Houston, Texas and I need your expertise. I’ve been trying to fix my 2016 chevy corvette stingray and I can’t do it anymore. I recently replaced my fuel injectors and I still can’t figure out why the code p0300 comes up. The computer states it’s multiple misfire . I checked spark plugs and coil packs everything looks good. What else could it be? Can I bring the car to you? The shakes a lot when I start it . And even during idle it shakes. I did remember I drove through a little high water and I remember as soon as I got out of the high water the car started shaking and then the check engine light came on. Please I need help , I can’t find the problem.
