Have you used a OBD-II scanner to find your issue? The car will help you find out what is needed to fix it. Remember to clear the settings after fixing something. This will help pinpoint your issue. If the same issue arises then the issue is another part. Read those codes supplied with the unit. It will help eliminate possible multiple problems. I have included what the codes mean in the following link How to Read an OBD II Engine Code Best of luck

SOURCE: 1997 DODGE RAM 1500 360 VERY LOW IDLE

I think you have ruled out the engine with all the parts you have replace. The transmission torque convertor is in lock up mode all the time. The engine is having to hard of a time to stay at the normal idle. The over drive clutches and soleniod are most likely damaged in the transmission.
I think you should take the vehicle to a trasnmission shop , The can check the torque convetror soleniods and pressure control soleniod.

The oil light coming on bothers me. I know you have the rebuilt engine in the vehicle but I think the oil pump in the engine is starting to go out or could be weak. The lower bearings connected to the crank shaft might be starting to leak. Have the oil pressure checked .

SOURCE: Idles rough and is hard to start apears to run better after it warms up. Have replaced the ICO, TPS, and the map sensors with no effect.

You can clean the EGR. No promise it will work. I have an idle problem on my `97 Grand Am Se. Shop told me I could clean it and it might solve my problem. 
Just remove the EGR with the 2 bolts from the top of the manifold behind the throttle body if you have a 3.4 v6 like I do. Then leave it upside down with throttle body cleaner in it. Fill the EGR level with cleaner and let it soak for at least 30 min or more. Then reinstall. 
This will remove any carbon on the inside which plugs the needle from pushing out at highway speeds. Hope this helps. If the problem returns in a week or so then replace with new EGR. New EGR is about $100-200! Cleaning seems to have helped my car did that about 3 weeks ago.
If you have a service engine light on turn the key to the run position on the ignition, pull the fuse to the ECM (batt) and disconnect the wire harness to the EGR. Reinstall it after a 1 min, That will clear all the codes in the ECM and reset everything.
Once you place the ECM fuse back in, start the car. It may stall but let it, DO NOT TOUCH ANY THING. The ECM need to relearn the EGR and engine from all it's sensors like the first time it was started. Just start it up again and it should be like the day it came off the assembly line and will relearn everything.
Good luck and just drive it like you always. If you decide to change the EGR valve, you still need to clear the ECM as mentioned above for the ECM to relearn the new EGR valve. Hope this helps and keep me posted.

What is a MAP sensor on a 2001 hyundai accent


It is a sensor located on the air intake to your engine. It controls how much air your car pulls in for combustion. Following is the wiki definition:



The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine\'s electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine\'s electronic control unit (ECU - computer that runs the engine). The data is used to calculate air density and determine the engine\'s air mass flow rate, which in turn determines the required fuel metering for optimum combustion and influence the advance or retard of ignition timing.

High idle o n a 1996 chrysler concorde. have change the tps and the idle air control valve. i think its a vacum line but i dont know which one. which one s effect the idle


High idle is usually caused by a vacume leak. First place to check is the cold air intake manifold. All hoses, throttle body, and sensors. Throttle Position(TPS), Mass Airflow(MAS), Idle Air Control Motor (valve) IAC. Controls Idle speed

A malfunctioning throttle system can cause both a high idle as well as an engine stall.

A dirty air intake or cracked air intake tube is often the culprit.

Try cleaning out the IAC (idle air control) valve. Located behind the throttle body on the B18c engines. Like the TPS it can get dirty and fails to meter air intake properly, giving the symptoms of a vacuum leak.

I have a 2001 hyundia elantra problem i am having is weather it has just been started or is up to operating temp. it will rev to almost 3k then down to 1500then back up to 3k then back down i believ this...


If this is something that occured all of the sudden, unplug the vacuum hose from the vacuum booster behind the brake master cylinder. Plug the hose and see if the idle settles down. If it does, replace the brake booster. Let me know, also, what codes have been pulled?
