Trying to get my 06 S3 Up and Running Again.
I've been an S3 owner since 2006. I recently moved back home to Louisiana and unfortunately my bike sat for about 3.5 years due to a debilitating injury I sustained. I've healed up enough to take the time to try and ride my S3 again so, I gave my S3 the once over of a lifetime.
1. Drained fuel (Non-Ethanol) and replaced with fresh non ethanol.
2. Flushed coolant system with vinegar and water. Topped off and ready to go.
3. Drained both brake systems and topped off with new DOT 4 fluid.
4. Changed the oil. Mobile 1
5. Changed the spark plugs with NGK CR9EK and gapped to .030.
6. Installed a brand new battery.
My S3 has a PCII USB and a Zard full pipe and exhaust. I was running a custom map I had done by HDF1 Motorsports in Atlanta. The bike always ran a little rich in Atlanta which resulted in my having to change plugs every riding season. I figured I would leave that map in place as now I am at sea level and that should help a bit with the richness of the map.
Anyway, when I fired the bike up for the first time with the new battery, it fired right up and seemed to run okay. So, I buttoned everything back up. I fired the bike up again and noticed it took a little longer for the bike to fire off. So, I took it out for a ride. It was then that I noticed the misfiring. While on the ride, the bike would kill when I pulled in the clutch and let the RPMs fall to idle. The misfires seemed to be reduced significantly when I kept the bike in 4th gear and was running about 5k RPM. So I kept it there to get back home.
Now when I try to start the bike, I can smell fuel, but the bike barely lights off. Ultimately, it stopped lighting off altogether. The only thing I could think is that perhaps I have a bad battery, so I promptly yanked it out and returned it. I'm going to be ordering a new battery this weekend in hopes I can get a better battery with a higher CCA. Leaning towards a lithium with 364 CCAs.
All vacuum lines are connected and like new. No brittle lines anywhere on the bike. If I do manage to get the bike to light off, it idles very roughly and eventually dies. I tried the 12 minute tune, but the bike can't get through it. I know the ECU is working because just as it is about to die, the RPMs pick back up and the bike continues to idle poorly. Eventually it dies before completing the 12 minute tune.
I'm not very good with a Ohm meter. But, I'm thinking I have a bad connector somewhere. Not sure what else to try if the new battery fails to solve the problem. I pulled the plugs again and they are clean. No fouling. So, I'm good there. Coil sticks look clean and there is no corrosion in the spark plug wells. Any help would be greatly appreciated. I'm hoping this is simple as I do not have the ability to get the bike to a shop for diagnosis. Any help would be greatly appreciated.
