Could really use some help

[gc73]

I will check the tag on the ECU

I do not show a CEL light on but will drive it with the jumper in place and see what i get. Last time I stepped through the process it showed normal

The car runs very rough especially when cold. Once it warms up it is better but still poorly. Hesitates and pumping the throttle seems to help.
Not much power going up hills but not a lot at any time. Likes high rpm's and seems to run pretty well at 3k or over. under it hesitates alot and will bog if you dont pump the throttle.
The MPG has to be horrible. If i reset the trip i can maybe go 200 miles at most on a tank. it smells very gassy like its running rich.
