Electrical problem from battery to computer?

[90Tsiman]

I have a 90 Talon TSi FWD and im having a hard time figuring out whats wrong here. When you start the car it goes crazy...does not keep an idle, up and down revs, check engine light comes on and ive checked it already and there is no code. I sounds ruff when it runs unless I get it above 3000rpms then it runs smooth. I put the code scanner on it and there is no code but it said the voltage level was low goin into the computer (9.8 on run, and 8.5 on key on position with car off). What im thinkin is that there is a wire problem somewhere between the battery and the computer...but could I be wrong? Some ppl tell me that its the cam angle positioning sensor but Im not sure? Someone please help me? Any suggestions would be great!

Thanks.......

if you know anyone wiht a logger, plug it in, and see what it has to say,

Can you tell me what a logger is? Is that the official name for it and who would have one? Does it check just vac lines or what else does it check?

Thanks
