2.5 1990 jeep flooding and missing?
my mom was driving to town a week ago and hit a bump in the road then it just started flooding and service engine soon came on.
so far i have checked the tbi and removed everything on the intake and cleaned everything all the way down to the pressure regulator on the return line, witch helped a little.
i have also changed the dist cap, rotor, plug wires, map sensor, tps sensor, and fuel filter and checked all the ground wires, that didn't help at all.
it seems the longer it runs the worse it gets when you first start it cold it sounds like nothing is wrong, and as it worms up it gets worse and it gets even worse when going uphill or pulling something to the point it will sometimes stall when going uphill and wont start back for several minutes when it stalls.
also sense it is a 1990 2.5l it has no computer to retain diagnostic codes even though it is a tbi engine i cant scan it or get any kind of trouble code to help.
is there anyway i can figure out what is wrong without replacing all the sensors or a full rebuild?

Did you ever figure it out
Hey man i just started having the same problems with my 1990 jeep cherokee i dont have flooding out or missing, but i believe it is my oxygen sensors since they help the computer decide how much fuel to inject, i was wondering if you ever figured it out
