1991 Isuzu Trooper

1991 Isuzu Trooper 6 cyl Four Wheel Drive Automatic 200000 miles

My 1991 Trooper has issues. Lately it will not go above 3000rpm and just falls on it's ass. Will barely go 25mph up hills and sometimes can't get it up to speed on flats. Seems to be running rich and using alot of gas. Replaced the MAF sensor but hasn't helped. Please help, only vehicle and I can not afford to miss work! Thanks!
