Question about 2004 Dodge Ram 2500

1 Answer

Considering buying a Jet power control module phase 2 for this 2003 Dodge Ram 4.7ltr. I have a true cold air intake, throttle body spacer and flowmaster single in dual out installed. The truck has 85K on it, will the chip make a noticeable difference in power and will it have any lasting negative effect on the truck once removed? Do the chips make the engine work harder or wear anything out sooner than it otherwise would?

No, it will not make a difference. I have heard nothing good about the Jet chips. With the mods you have, the factory ECU will work just fine. If you start changing cams, and doing port work, then you may want to get a tunable computer, and have someone with a dyno tune it. Otherwise, you should be fine.

My dodge durango is 06 it accelerates by itself when i do a stop or in parking can it be the? Air control valve or the throttle position sensor

You may want to clean or replace your idle control module called the IAC which is mounted to your throttle body. This is a stepper motor which controls air threw a passage in the intake. This can cause the engine to rev and allow more air to pass threw the intake. Acting like mashing the gas pedal down no difference.
Your PCM or Power Control Module controls this stepper motor by controlling voltage threw windings which open and close. If this motion is hindered by the IAC this motion can not happen fast enough and Bam you have the problem you have described. Both get out of sink and can not keep up with one another. If you need any further assistance just ask

Why won't my truck stay running when I'm not

Try cleaning your throttle body. Over time on high mileage vehicles, the throttle body butterfly valve will gunk up with sludge, and dirt. This will prevent air from entering the intake manifold while the engine is idling, causing low idle/stalling. A can of throttle body/carb cleaner will do the job. First, remove the intake tube to get to the butterfly valve. Spray a small amount of throttle body cleaner directly into the intake, and wipe any excess fluid with a cloth. Also, inspect your air filter. I hope this helps

I have a 1999 dodge ram 1500 with the 3.9 v/6 and standard transmission and it is under powered is there anything i can do

You can get a less restrictive exhaust system or cold air intake. Even a throttle body spacer. What i think may get you the power you are looking for may be a hand held tuner that plugs into the OBD II port and controls the computer. These mods will also help somewhat with your fuel economy. Maybe if you want to spend the money gears would be the ticket.

Does a 2001 have a iat sensor?

Idle Air Control (IAC) Motor OPERATION The IAC motor is mounted to the throttle body and is operated by the engine controller. The throttle body has an air control passage that provides air for the engine at idle (when the throttle plate is closed). The IAC motor pintle protrudes into the air control passage and regulates air flow through it. Based on various sensor inputs, the engine controller adjusts engine idle speed by moving the IAC motor pintle in and out of the air control passage. The IAC motor is positioned when the ignition key is turned to the ON position.

OPERATION Found on V6, V8 and V10 engines, the intake manifold air temperature sensor is a variable, thermister type which reacts to temperature changes. In cold air, its resistance is high. As temperatures increase, its resistance decreases.

Fig. 2: Location of the intake manifold air temperature sensor — V8 engines

The sensor element itself extends into the intake manifold air stream to provide input voltage to the engine controller. This signal is used along with signals from other sensors by the engine controller to determine the fuel injector pulse width.

I have a dodge ram 1500 SLT,2001,2W/drive,V8-383..A GAS PIG !!!! Is there anything I can do on a budget to get any better mileage.I'm only getting about 10 MPG now. Any little bit would help in these...

pigs they are. here are a few basics to check first proper tire pressure low pressure causes high rolling Resistance,condition of tune up and filters check and or replace air filter, spark plugs,ignition wires, fuel filter, distributer cap, and rotor. take a look at the brakes make nothing is causing drag caliper slides rear shoes hanging up ect... as this will cause more power to move truck. if there is a lot of junk in the trunk extra weight get rid of it. there are aftermarket parts that help as well free flowing cat back exhaust system, k&n air filter this will increas air flow and give the truck a little more power as well. remeber RPM`s=MPG`s
