SYMPTOMS:

Well as some may have read before, I was having issues with my car running very poorly after a Comp XR270HR-10 and Brodix IK200 Head swap on my 350 Speed Density TPI. I also had PCMforless burn me a chip.

I am getting poor idle, stalling, missing, backfiring, shuddering, hesitating, bogging, no power at all. So I adjusted the IAC and TPS to spec, and they are both in order. I am getting a code thrown at me as soon as the car starts up, but when I jump the ALDL connector A to B, I get no error code. I have checked, rechecked and rechecked vacuum line routing and quality, everything is perfect. I got new plug wires and are routed away from the headers, no burn-through. I also statically relashed the valves, and they are spot on.


DATALOG:

Here is my datalog, it's a little over a minute long, and I had the counting at 10 counts per second. If it's too long, I can redo another log with less counts:

I idled for a while, revved to 3-4k, idled, and back to 3-4k, idled and cut it. I was holding an idle to 1200-1500rpm because it wont hold on its own. It went into closed loop at around one minute.

There are some values that I am unfamiliar with, but things such as TPS, Spark Advance, A/F ratio, ect all look in order to me. What do you guys think?

 

Well I got a better datalog for you guys. This one is of me starting up and driving around my block. (Less record counts this time, should be easy to read =]) Let me know if I left out any really important info this time...I tryed to cut down on things that I knew were sending back a null signal, or I knew didnt pertain to my issue.

As for the Coolant Temp: The sensor is not installed, I still need to find a place to put it since my new heads dont have provisions for it.

And the DTC error is just VATS acting up.

 

Your best bet is to send the data logs to Alvin. Even if I tell you what is wrong you can't correct it.
