Every since it's cooled off outside it seems I developed a part throttle problem. If i stay at half throttle my AFR goes super rich 10.2:1 according to my AEM uego but that's as low as it reads I think. The car also starts to buck and makes pop sounds sort of like maybe misfires but it sounds to be in the tail pipes. If I back out it obviously goes away and if i floor it will also go away. It's most troublesome in the low 40's when I can't get the car above 180 water temp and 170 oil temp.
Any ideas?

Mods-> COBB AP tuned by MM, Mazdaspeed CAI,*note* (I had to back out a few tunes after installing the CAI as I went too lean. This also means my MAF is off. made the switch in the summer with no problems.), Mazsport Ignition solution less than 10,000 miles, and the plugs are ok i checked them 2 weeks ago and cleaned them also they're right at a year old. Plug wires checked and secured properly. Full TurboXS exhaust.

Damnit wrong place i thought i was in TECH. TEH STUPID IS BURNS ME!!!

I don't think that it is due to the temp???

I have similar mods and live in CO and it goes from the 90s to the now 20s/30s and I don't have any issues...

I would start the tuning process all over (if you can) with MM since you initially started with a Stock intake and swtiched to the MS/AEM. G/L

wtf I didn't even think to uninstall the map back to stock I did however reflash it the other day. I'll try that and see what happens. There weren't any problems untill it got cool outside so I dunno. The tuning with jeff is a nogo I dislike his methods of communication or lack there of.
