Finally got around to checking A/F turns out the engine is running LEAN! Like 18:1 LEAN :OMG:! (why did it smell like GAS!, more on that later) So I picked up some new 02's and got them installed and sending a signal to the EEC (broke the speedo in the process, grrr) and I finally got my data logger working. Both 02's are reporting a signal just the BANK2 (drivers side) goes to 1.666 and holds (way lean). BANK1 was normal (.7ish). So I put the wideband in the passenger side and it was a normal A/F at idle 15-14.7ish. Perfect. So only one side was so lean. WTF!?! mate? Now I know it isn't the tune (in this tune I haven't messed with individual cylinder timing/injector dwell, only the base). I pulled out the SnapOn Vantage Scope and checked all the Injectors and COPs to make sure they were firing, yep. So then I pulled the COPs and ohmed them, perfect .53, then I pulled the plugs. All VERY white (lean). This was about 3:30 Friday so I decided to call it quits and give up getting it ready for the track. I went inside sat down and lamented about my failure, then I got the bright idea that maybe my PCV valve was leaking letting un-metered air into the drivers side so I just had to go back out and check. Nope, not leaking. While I was poking around I noticed that I had used an old vacuum line to hookup the A/C and Fuel Pressure regulator. I had the one I use to use laying right there so I ripped that one off and put on the old one. Fired the car up and sure enough, A/F at idle was a sold 15-14.7, DAMMIT! That's all it was! MotherFuck! So I looked at the clock, it was 4pm.
Trailer was packed full of spare body parts and crap that I didn't want in the garage. I knew it'd be a good hour cleaning the trailer out, another hour packing the car/tools up and another hr in the house before I could hit the road for SP. The speed bug got me and I said fuck it and started cleaning out the trailer. Ended up pulling into Summit Pt around 9:30 and unloading the car in the PITCH DARK (put some damn lights up please!) and dropping the trailer.
Saturday AM I took the car out in the first instructor session with ANDY! in the passenger seat watching the A/F. Sure enough we hit WOT and he yelled out 12.5! Great! Lets have some fun! After another lap or two I started smelling raw fuel again, "Hey, whats the A/F now?!" 12.5, he yelled, then I said why the fuck does it smell like gas! We came in shortly after, ANDY!'s eyes appeared to be on fire from the gas fumes and were barely open (that might be the Asian in him though, not sure). Then mike pulled in and told me I was spilling gas all over the track, ahh, that's why I thought the car was running so rich, haha. Made a few futile attempts to repair the leak but it was to no avail. I think it's leaking out around the filler neck/grommet in the tank. I have some spares so I'm just going to replace both and hope for the best.
