My 2006 Mustang GT 5-speed has developed some warm weather problems. First, let me give some background. I installed a Bullitt CAI and Brenspeed SCT tune a few months ago when the weather was cool, but I was getting pinging at 4K and above (WOT). I tried running 91 octane (the highest here in CA) but it didn't take care of my problem. I left it like this and just didn't take it above 4K.
Well last week the temperature got into the mid 80's and I started hearing pinging at low RPM's just driving around town and on every shift. I reverted back to the stock intake and tune and that seemed to clear it up. I also did not get anymore pinging at WOT above 4K.
This week, the temperature has hit the low 100's and now my car bogs everytime I leave a stop light and on every shift. It will just barely accelerate away and then when it gets up in RPM a bit it will start accelerating like normal. But as soon as I shift it it's back to bogging again. I thought it might have been my AC so I shut it off but that didn't help. I can push it to full throttle and it just makes a deeper sound like it is loading up and goes nowhere. I also tried get the RPM's up into the 3500-4K range before shifting and it would still bog. I also notice an occasional ticking sound when this happens. This has happened the last 2 days where the temp has been 90-100.
All of this time I have been running name brand 91 octane and I tried several different brands but it didn't help.
I work swing shift so I drive in the hot afternoon but come home at midnight and the car runs fine in the cooler night temps so it's definately a warm weather problem.
Does anyone have any idea what the problem could be?
