After I posted the above datalog yesterday, I got to thinking about the inconsistency of my tps signal. I was going to start tracing voltage and continuity starting with the connector but when I touched it, the signal dropped off completely. So I started moving the connector a little in different ...

Here's a datalog. Looking at the gear, it shows as though I switched gears like crazy. Toward the beginning and at the end it shows that I went through all 6 gears and then back down while only travelling 20mph. What sensor feeds this? I know that I had to push in on the clutch a lot to get the ...

I had my alternator checked and the regulator was bad. I opened the top of the battery and all but one cell were dry, even though the battery checked out to be ok. So I replaced both the regulator and the battery. I was still having the same problem and I noticed fluctuation in my tps; I could open ...

Here is a datalog with the alternator wire and plug both disconnected.

I just unplugged the 4-wire plug. I can disconnect the ground as well as the plug, and even take the belt off if needed. Just let me know.

Is there anything else I can provide to help diagnose this?

Heres a datalog with my alternator unplugged.

I haven't had a chance to datalog again but my car was cutting out again last night at part throttle so I checked the voltage at the battery. This time it was holding constant around 14.4 but it would occasionally drop down to around 12.8-13.0

any update on this?

I just checked the voltage and battery shows 14.5v, B9 shows .30v, and B10 shows 14.2v. There were some small fluctuations of around .2-.3v w/ the voltage at the battery and B10.

Also, the car starts up without a problem every time. I'm going to have the alternator tested to make sure its properly charging the battery as power is being drawn. Any other ideas as to what could cause the fluctuation?

I have not tried to scale my tps. In the last datalog I simply didn't use much throttle as the problem I've been having only seems to occur at light throttle. In terms of the battery, I had it tested and it turned out to be okay.

Here's a new datalog, it was too large to post as one file so I split it in half.

Yes, I was referring to battery voltage. The only changes to the electrical system are hardwired injector clips and the necessary sensors for the kpro. I set the tps based off of voltage and all was fine for a day or so but today its cutting out again and I have not touched anything since I reset ...

One more question as I'm tracing voltage. On the datalog I posted, does the voltage look unstable enough to be problematic? I see the voltage dropping over and over again, even though it's only .5-1v. I haven't noticed my lights or radio losing power when my car cuts out but the voltage drop just ...
