built 2.5l help
I have an 02 wrx non sti with a frankinstine motor in it. the casting numbers on the block say it has an 06 sti block but the heads dont match up. I bought the car like that so im not sure what it has. But piston 3 cracked and was buring oil bad. so I removed the engine and had it rebuilt. now that is is back in it misfires bad on cylinders 1,2, & 4 and has a DTC p0340 for cam shaft sensor bank 1 circuit malfunction. The head that is on the engine does not have a spot for a bank one cam shaft sensor. I have a cobb tunner tune on it. For life of me i cant figure out why it wont run. Its getting spark and fuel. also i was looking through the live data and found bank 3 stft and ltft to be at -100%. Any help would be greatly apreciated.
