My car under normal acceleration runs good, Under hard acceleration it flutters.... i had it scanned and the #3 cylinder is misfiring. I changed the plug and made sure it got spark. I have a turbo and a walboro 255lph pump with plug and play racetronix fuel system and 42lb injectors. It accelerates kinda sluggish but still goes. My fuel pressure dropped yesterday from 59 to 40 and now stays around 48psi. i dont know what it is and am in an area in upstate NY were they dont work on too many F-bod's. Any suggestions? i had some shitty gas and refilled it with a better premium and added some octane boost, not sure if the shitty fuel messed anything else up or not? Ran better after the fuel was added but still puzzles me.. I guess i will check the fuel filter this weekend and see what is up. please send some suggestions. thanks
