I have kind of same problem...my car goes into open loop at idle( pig rich 10.0) and then bouncesback to normal 14.7. Does it every othet stop. I replaced my O2 ensor and nothing. I do have a p300 code though for misfire. Is annoying.......

Update!
Ok changed out the old o2 sensor and did like 6 pulls in 3rd and had no problem then I got off the interstate headed back home did a lil town driving and few short 1st n 2nd gear pulls and it went full rich again BUT this time it threw a ******* code lol. P0101 mass air flow sensor! so im guessing the sensor needs to be replaced because iv done cleaned it 2 times already. always im just happy to get a ******* code for once so I have an idea of what is wrong.

Hey man i was having the exact same problem in my redline, what worked for me was to just go into Engine Diag in HPT and disable the test for P0101. This should stop it from pegging full rich, even if this does work you should still replace MAF and enable P0101 test to try and properly fix it.

Wow, i just reread my post....worded that horribly. lol trying to tune out a mechanical problem is a terrible idea. What i meant was more along the lines of if he's having drivability problems he can disable the code temporarily until he gets the new maf sensor. In my case i couldn't drive my car over 30mph without pegging rich and the only fix for me was to restart my car, with the test disabled I could at least drive my car until i got my new maf sensor.

What injectors are you running? Some of the injector tables floating around the HPT forums for 80s are garbage and will randomly cause a retarded rich situation

Yea but why disable it when theres obviously a problem, and it needs fixed..? We get CEL's for a reason bud, to help us identify, and correct.

From reading I've done on yellowbullet and hpt forums, some cars and pcm's are just finicky. Ours is one of them. There are MANY tables in the PCM that we can't even SEE with hpt, and were likely some that are used in airflow sanity checks.
To sum it up, disabling p0101 gas absolutely zero negative side affects. We can NOT say for certain that it is showing a true problem on a modified car. All we know is that it sees something outside of its parameters for that code.
After you have done every normal check, and it's still there, shut it off. You will be fine. My car has been this way for over a year with no problems.

Alright I have finally fixed my car! Woot Woot!, I did replace the downstream o2 it had a burnt white wire, and I spoke to zzp about the injen intake, and he explained to me that the placement of the MAF senor on that intake is not a good spot. So although the problem was corrected with the 10.0 flats, I still had the the bouncing of the idol. I went ahead and took the injen intake off, and put my factory intake back on. I also drilled holes in the bottom part of the intake box to allow for more flow. I also unplugged the neg battery cable when I did this. Got everything back together, and low an be hold car was running beautifully. Cant be more happier. I would highly suggest doing the tock air box mod, my car hasn't responded as good as it does now. Only took 2 months lol but its fixed. Only thing I do have now is the map sensor keeps kicking a cel..? unsure if that might be just the bypass valve might be bad. unsure tho. Good luck bud I hope everything works out for you.

Well I installed the new maf and its still same ****, im seriously thinking about returning to stock and trading this in for something else. Right now I know that from looking at current and past logs, my car had stft that would bounce up to +20 and then go to -20, im not sure whatelse to do at this point Iv replaced maf sensor, upstream o2 sensor, tried different tunes, checked for vac leaks(didnt find anything) and I dont have an exhaust leak that I know of. any ideas? or maybe what to trade it in for lol. it have to be something around the under 20k range.

Try returning to stock one part at a time and maybe you can find the prob that way! If by then your at stock and prob still there then you know what's up.

The downstream o2, and the placement of my MAF on my Injen intake was causing me to run rich, st.uiped rich like a flat 10.0.. Car bogged down and ran like ****. Just try what I said to do, what would it hurt?

Ouch, you have a injen intake right? At least go with zzp's cai I grunted you that injen intake is your biggest problem just because of where and how they want the maf sensor on it.. It's reading to much air flow, and a downstream o2 will read that causing the car to bog down or limp mod or run just flat out shity.. Not only that but when you start the car it revs up all high then starts bouncing and is just ridiculous. Hope this helps its frustrating trust me I know lol.
