96 Jeep Grand Cherokee 4.0 just got it 3 days ago runs good but 3 times I barely parked on a hill I go to take off Kind of looses power/bogs out then kicks back in and it's not a steep a hill at all and 2 times were right after I filled up and they were all right after I just started vehicle get in take off about 3-5 seconds later it bogs out then kicks back in does it about 1-2 a day since I had it. Still has plenty of power no codes any help be great

Could it just be not getting fuel to pickup tube

You are sure the CEL isn't burned out or did you plug it in and read it?

jonwalden68

Yep check engine light works

jonwalden68

It lights up when I turn it on but don't start

dave1123

Do you have any trouble codes set?

jonwalden68

No codes

jonwalden68

I just wonder if it could be pickup tube since most of the time it has happened been after a angle or incline or after a fill up but I can't ever go back And do the same hill or angle and make it do it twice

Also on lugging in overdrive you can hear the fuel pump having a loud humming

If it weren't for the check engine light I would say it was probably an O2 sensor. Hopefully one of the vets will find this thread and give you some good info.

jonwalden68

Yea I hope so but no there no codes on it and I put 300 miles on it

jonwalden68

I really don't want to just throw parts at it. I thought about changing the tps sensor

jonwalden68

Fuel filter changed still doing the same

Idle is getting a tad bit rough
