Hi, I have a 2000 Convertible, 3.8 V6...
When I first start up and go it runs fine. When I park for a short while (say to go to the store) and come back out it starts fine, but begins to miss fire. If I let it rest for a longer time - it acts normal again. It has not been abnormally hot, 75 degrees here. Thought it might be vapor lock... but it has not been that warm.
I have done the following:
>SeaFoamed it (as a gas additive, not through fuel rail)
>Check the MAF (and cleaned)
>New air filter
>Changed gas filter
>flushed cooling system
And it still acts the same.
Could it be DPFE sensor going bad?
It does through a code, and had Autozone check - they said it was missing on Cylinder 2.. weird though how it only starts missing the second startup after a short rest.
Any ideas? Thanks
