Ok guys, I really need some help. My rig keeps going into limp mode and the check engine light comes on. Checked the codes, it is P0301, P0302. Yes, I have read through the many posts on here for this issue (misfire). I took it to the dealer, they said I needed a new belt. I called BS and here's why: IT ONLY HAPPENS WHEN I USE THE WHITE (PERFORMANCE) KEY!!!
The machine will run without issue with the Standard (Green) key, no matter how hard I hammer it. I can run it all day without any codes, any check engine light, any issues whatsoever. But as soon as I put the White key in, I can just drive it around my block once at 20 mph or less and the check engine light comes on. When out in the desert this last weekend, it will do it no matter how hard or soft I drive, within 15-20 seconds of moving.
I have checked all my grounds (which if this was the issue, it should happen with either key). I have taken out and cleaned the spark plugs (again, if this was the issue, it should happen with either key). I replaced the belt (I can understand that the Performance key allows the engine to make more power, but if it was the belt, it shouldn't happen just cruising around my block at 20 mph). Still happening!!! This is driving me crazy and my dealer doesn't know chit. Any help from you guys would be greatly appreciated! Again, to be clear, this only happens when using the Performance key in the machine, which I just can't understand.
Thanks in advance for your help!
