Ok so I have a 04 wrx sedan. Rebuild ej205. Bpt 16g. Catless exhaust. DW 650cc. Walbro 255. Cobb sf intake. Inlet tube aftermarket. Protuned.
Ok so the problem is the tach jumps from 4k to 5.5k back fires and runs like poop. No CELS though. Changed plugs and added some ground from the ecu ground (local tuner and subaru speed shop told me too). They also said to do coils too. I haven't tried that yet.
The weird thing was I did grounds and plugs tonight. It ran good for about 2hrs and it then started to do it again. I have no clue on what's going on. I'm getting a tactrix cable and a laptop so I can datalog and send to my tuner.
I was hoping someone on here had some answers or had this problem before.
