I've been dealing with this issue for a while, but I'm really getting sick of it. When I start my car up after its been sitting for a while, it will run fine for about a minute, and then it goes very lean and if I try to drive it, the engine will buck and stutter and stuble and pop. This will last for about 30 seconds, and then it goes away and the car runs fine. During this 30 second period of crap, the car idles amazingly steady though, but it sounds very different...its hard to explain. It won't happen if I shut the car off and then start it back up right away. But even if I let it sit for about 20 minutes when the engine is still somewhat hot, it still pops and stumbles.
At first, i thought it was because I replaced my left o2 sensor with a wideband o2 sensor. It did have a simulated narrowband output though (PLX M-300). I recently welded in a seperate bung just for the wideband and put a new stock sensor back in, but that did nothing.
So it seems that the computer is going into some sort of loop mode for a little while. Could my right o2 sensor be going bad? If anybody has had similar issues and could offer some input, I'd appreciate it.
