EDIT: LOGS NOW POSTED
Hi there,
I had my car tuned a couple of years ago and since then I've had a cold start slow surge + dies. I can't seem to figure it out so hopefully one of you log gurus might point me in the right direction. Once warmed up it runs flawlessly and hot starts are fine. I've also attached a video of the cold start as well as a log warming up and once it reaches 140f.
The main issue is it goes to 1500 or so, runs well, starts to drop, leans out and dies.
Thanks for the help in advance.
2). Verified mechanical timing?
Yes
3). Verified base timing?
Yes
4). Ignition system
COP or Stock Coil: Stock
Wire brand and Age: NGK, 6 months
Spark Plug brand, type and Gap: NGK-BPR7ES at .028
If you are having electrical issues, you should follow the troubleshooting method inside the FSM (that you can download off this sitehttp://www.dsmtuners.com/threads/download-the-1g-service-manuals.344490/http://www.dsmtuners.com/threads/download-a-2g-service-manual.324090/) and post the resistance reading.
5). Motor health (Compression Test)
I haven't checked compression recently, it has about 6000km on the build if even, runs great otherwise.
6). Performed basic throttle body adjustments?
Idle Switch: Verified with Link
Throttle Cable: Yes
TPS: Yes to .63v with Link
BISS: Yes, hot it idles well.
7). Compression ratio
9:0:1
8). Any known bad sensors or brittle wiring?
No
9). Any DTC/CEL codes?
No
10). Electrical system
Car off (not running): 12.4 volts
Car running: 13.9 volts
11). Base fuel pressure and injector values
Base Fuel Pressure: 43
Injector Size (cc/min): 850 FIC injectors
12). Properly calibrated and configured wideband sensor
Sensor Brand: AEM UEGO
Calibration Date: UNK
13). Type of fuel
Type: 93 Octane from pump
Percent of Ethanol: 10%
