This story starts off by putting fuel injector cleaner into my 90 cherokee I6. I came outside after letting it run for a few minutes to find a very large puddle of gas under the car probably 2 gallons. Turns out the fuel pressure regulator sprung a leak. After replacing that and putting it back together THe injectors started leaking so i put new O-rings on the injectors. Changed that put it back together then two of the injectors sprung leaks in the middle of the injectors (where the metal is crimped together) so all of those got replaced. Now to the problem, the idle is off. When i start the jeep even in cold weather it idles at the normal speed 700RPM but then once it warms up its running 1000-1100RPM all the time. I unhooked the battery for awhile thinking i could reprogram the fuel map on the computer didnt work. Any suggetsons greatly apprciated.

Dirty throttle body.
Bad IAC motor (idle air control, front of throttle body next to TPS).

Ive already dumped a ton of money into this thing over the last 3 years for lingering issues that never resolve themsolves. So at this point before I fix stuff is there a way to test the IAC if its bad? Also is this another thing that the fuel injector cleaner may have accelerated. Apparently my fuel system was held together by dirt.
As for the vacuum leak we did check for vacuum leaks but didnt find any.
