I possibly thought the cats coulda been clogged so i unbolted the exhaust and it still pops through the intake and has a rough idle. Nearly everything on it is brand new. Head, spark plugs and wires, egr sensor, tps sensor, Only thing i think it might be is injectors, maf sensor, or possibly a fuel pump. I did a fuel pressure check and i believe it was around 40psi? It was last summer when i checked it. Thing is when i take it drive it seems to drive fine. I think it possibly needs a new clutch as you can hear it through the shift handle and don't hear it when you engage it. But that's possibly because that's how its suppose to sound?? Idk? Lol. Heres a video of it trying to start. You can really hear the pop. And Ive checked the timing and its on the dot. Once it starts to stay running its rough and low idle. It seems to drive just fine though. Just has a hard time getting running.
