Well I want to be able to run at CAROLINA THUNDER on Sunday but the Mark started spitting and sputtering a just a little about a month ago. So I took it over to Barrys last week and they changed the plugs and cleaned the air filter and said it was running great. I picked it up and it started doing it worse than ever. I took back and we worked on it all day. It has good fuel pressure even when it starts to doing it. Replaced the O2 sensors and didn't help. First cleaned and then replaced the MAFS and didn't help. Replaced the crank sensor and again no help. PS It shows no codes as if all is well ?? Plus when it starts to spit and sputter the air/fuel gauge goes full lean.
