My 2004 jeep grand Cherokee run great when I get in it in the morning then I drive 4 a while & when I push the pedal 2 the floor it has now power it bogs down then I let up & it kicks in and runs rough & still has no power. Can smell gas & white smoke comes out of the tail pipe thinking to much fuel? I drove 20 miles yesterday & then it really went bad & only could get it 2 go about 8 miles per hour :( it sat for 6 hours got in started it up was fine & it drove like new but didn't want to go 2 far in case in ran into the same problem? Please help?

Scan for codes and check fuel pressure with a gauge

Disconnect it after the converter because normally a bad converter will throw a code. If it still does it check vacuum at intake if 15" or below then it may be the converter. They are covered for 80,000 miles by warranty
