If anyone can review a log of mine, I am not sure as what I am looking for. On occasion I have a throttle seeking issue, after the car has warmed up. It will just bounce back and forth between idle(750) to 1000 and then it will settle, I can update with another log tonight. No seeking happened during the first log time.......

I will have to email you a file, because I tried the attachments function and it says it is an invalid file to load.

I have, 15G's, walbro 255, 550cc injectors, SAFC II, M&W ignition box and coil on plug set up.

Back story - Had a blown head gasket, so I got the heads redone. Put everything back together, installed new IAC, TPS, CAS, and temperature sensor for the ECU, along with new 02's. Set base ignition timing with light and procedure as outlined on Stealth316. All vacuum lines are new. KrankVents. Just installed new silicone intercooler hoses(ebay).

After I started it for the first time, the throttle would not stabilize. So I re-installed my old IAC throttle settled a little bit but it still searched. As time went on of me driving it, the throttle rpm definitely lowered and now is much more normal, it still searches.

And as far as I know I have good gas, on its third tank now.

Bumping?

Make sure there are no rough transitions near idle on your safc

Ok, but what do you mean?

Well say you have -30 at 750 and -38 at 1000 or something like that. The afr will change as the engine speed just slightly changes and cause the idle to hunt. I had that problem running speed density once.
