My tune is screwed. Someone please look at my log.
I hate to beg but now I have problems. I have wot runs idle runs logged.
The problem is now I have a car that runs lean then rich and back and forth. WTF its never had a log sheet like this. LTerms go from -6.3 to 4.7. I changed the oil as usual and afterwards it started to sputter when I first start and take off. It finds idle fine the problem is when I drive off it hesitates several time then it catches and goes. It stays fine until I cut the car off and crank it again. Also today when I cranked it it had the STRONGEST smell of gas ever. I immediately shut it down then atapped it again.
I have edit and autotap and have no idea what to do I cant tell if its running rich or lean b/c if fluctuates so much.
Thanks,

Re: My tune is screwed. Someone please look at my log.
It sounds like something broke on your car and it is now running PIG rich.... O2 sensor went, something left unplugged?
I would check the following connections first before going after the tune. Additionally, check your freeze frames for any SES codes.
Engine Coolant Plug - To the right of the driver side head.
Forward O2 sensors - Check plugs and connections.
MAF Plug - Make sure it is plugged in
Coils - Make sure you ignition wires and plugs are connected and up to snuff.
And if all of the above looks good, put the stock tune back in the car and see if the rich condition cleans up. With your mods, the car should still run okay on a stock tune. It may have trouble idling, but the car should not stumble when you climb on the gas.
Good Luck,
Kevin

I cant beleive I left this out. When I changed the oil the drivers o2 was unplugged so I plugged it up. I dont know how long its been unplugged. Maybe that one went bad. I have 4 more so I will try to swap it.
In autotap how to you check the drivers o2 to see if its any good at all?
Thanks NoGo,
I will check all youve listed tomorrow.

autotap, in the table section put up B1S1 for driver side front, B1S2 for pass. side front, B2S1 for drivers side rear, & B2S2 for pass. side rear. if you get a constant number of .445, your sensor is r.i.p.

Thanks z28man I guess thats not the case. Should I reset the computer since I plugged it up. I have no idea how long its been unplugged. I tried the factory flash and it does the same thing.
NO rich smell anymore but the hesitation after startup is still there. Nothings unplugged. Oil pressure is normal and the temp is normal also.
Thanks guys for the input.
It had to be plugging that darn sensor in.
Anyone care to look at my log and tell me what you think? I dont want to blow my engine I cant afford a dynotune right now...
Tis my sob story...
