Re: 91' Cherokee, please somebody help me
Hah, seems like it's much better now. What I did? Just like you guys told me
(some of those things). First, I cleaned plugs for TPS and the other one (I
think it's for cold start, just nearby). Then, in meantime, tranny oil.
Transmission sump was very clean, even magnets were only little black. But
after oil change, Jeep runs more and more smoothly (?!) Is it possible that
something was wrong with oil? Maybe would be nice to "wash"one more time
with fresh oil just because some of old oil was still in converter?

It's entirely possible the tranny fluid had broken down or adsorbed water from
years of heat/cool cycles. <nicpick> Tranny fluid is not oil. If your going to
abbreviate it use "ATF" Automatic Transmission Fluid. </nitpick>
Cleaning sensor plugs will have a gradual effect as the Jeeps computer (ECU)
and the transmission computer (TCU) slowly adjust back to normal operation
ranges.
Did you clean out the Idle Air Passage (IAP)? THat will also help smooth out
idle. http://members.***.net/wilsond/tb/tb.html

This Idle Air Passage (IAP), is it small channel in throttle body with
something like solenoid on it? It has connection also, just near TPS?

Exactly,
That connection is a solinoid that adjusts the flow of air and sets
your idle. The internal passages get crud and dirt buildup that keeps
the little pintle from moving smoothly. If you take the solinoid off
do not.. do not.. pull the pintle out, that will kill it.
That's why it is easier to just spray some cleaner through the slot.
