Question about 2000 Jeep Cherokee

Hi, my problem is about the engine idle cold because if its hot the rpm rises a little enought so it doesn't do the trouble that it does when i accelerate it, so the troubble is like a failure in the continuity of the acceleration , that fail its like when a spark plught doesnt work .. but if i accelerate it fast it doesnt do the fail it just do it if its idle cold and i try to accelerate it softly... im from venezuele so please excuse my bad english XD and thanks

    hola la cuestion es que recien prendida la camioneta con el motor frio pues y en minimo, si la voy acelerando a una velocidad media es decir que no le doy pedal a fondo de una sino normal. hace una falla como si fuera un cilindro apagado o una falla de tiempo porque corcovea pues no acelera uniforme todo esto ocurre mientras voy comenzando a acelerarla ya cuando suben mucho las rpm se le quita y sigue normal, hasta q le suelte el pedal y tenga q acelerar de nuevo desde minimo, lo curioso es que si esta caliente, q sube un poco mas el minimo por los electroventiladores no hace esta falla de ninguna forma, trate de subirle el minimo de motor sacando el TBI pero si apenas muevo el tornillo de minimo suben demasiado las rpm y al acoplar la caja golpea muy duro, es muy sensible a graduar el minimo por ahi, no se si hay otra forma de subirle un poco el minimo para que no haga mas la falla gracias!

Check the throttle position sensor, map sensor and obviously the condition of the ignition system overall. Your injection system is also suspect in that dirty injectors may give a poor spray pattern that can cause low speed miss (though electrically they appear to be OK)

Engine making a clack sound when idling and oil pressure is between 5 to 10 psi.


Sounds like it is time to have some work done or to move on to something newer.

Low oil pressure


55 is max (pressure relief)
20 is typical hot engine at 800 idle. and rises as RPM rises.
your post tells neither , temp, or RPM

Engine wont catch


Catch?
cranks fast
starts every time.
idles fine hot or cold , or both? hot idle not too fast.
i race engine , in park and neutral, I can hit 3500 rpm easy, can you.
i release brakes, (brakes are not packed in ICE , are they?)
I select 1gear or reverse (A/T or m/t)
the car moves or dont move, which is it, my guess catch = no move at all.
I try to drive, i look at RPM and MPH
RPM moves up and MPH track.
track means they both move in a linear progression.
RPM rises and for all RPM increases MPH also increases.
does it?
if all that works then we have an engine power issue.
weak on hills?

Idle speed valve


cold or hot. there are 2, on all suz engines (what transmission, 3sp,4sp or 5sp)
post symptoms, sure bad idle but hot , cold or both
hot means engine is at 180F or more holding......
is hot idle above 800 RPM or Below?
is the idle surging out of control hot?
Does hot idle (spec 800) drop in RPM with cab heat fan on and Headlights turn on at the seam time.? (yes, bad iSC funcition)
if ildle is low, say so, that is cause by other bad parts. (or set wrong)

Idle problem integra


check the MAP sensor (manifold absolute pressure). The ECM (car computer) uses that to keep idle at minimum 750 RPM. It's normal for it to run high when cold. These small 4 banger motors typically run hot, and they won't run right IF they're NOT running hot, ergo the idle is usually high when it is cold so as to cause it to warm up quicker. If the RPM's drop below 750, suspect the MAP sensor, &/or ECM.

2001 dodge intrepid ...rps suddenly rise when when fans turn on


how much? if a little this is normal computer compensates for the decrees in idle to keep idle at the right rpm. In the cold weather the RPM will increase while in idle for 10 mins to keep the engine at correct operating temp. =If you need more assistance write me, Lee

1988 Dodge Aries K 2.5L Engine Trouble and codes


CODE 14
Trouble Code 14 indicates that the Coolant Temperature Sensor (CTS) is reporting abnormally high readings. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operations among others. The thermistor used has a low resistance when hot, rising as the coolant cools. This error then, indicates a very low resistance in the CTS circuit.
CODE 15
Trouble Code 15 indicates that the Coolant Temperature Sensor (CTS) is reporting abnormally low readings. CTS is used to control fuel mixture, timing, idle speed, TCC and EGR operation, among others. The thermistor used has a high resistance when cold, lowering as the coolant warms. This error then, indicates a very high resistance in the CTS circuit.
CODE 33
Trouble Code 33 indicates that the Mass Air Flow (MAF) sensor is reporting more air is entering the engine than makes sense based on RPM and TPS. The MAF sensor produces a frequency output; around 30 Hz at idle to 150 Hz under acceleration. The frequency varies proportionally to airflow. The ECM monitors the frequency and thus determines airflow into the engine. Typical idle MAF is 5 to 7 grams per second.
