Question about 2004 Dodge Intrepid

3 Answers

Low Mileage The 2004 Dodge Intrepid 3.5L I just bought does only about 13 MPG. It has 73,600 miles on it. Mostly city driving. (Pumped at the same gas station, same pump, same time of the day). Change oil/filter recently and air filter is clean. Where do I start / what else to look at first?

  • I asked them to use 10W30 as per the manual filter is Napa if i am not mistaken.

  • I added the fuel additive to a full tank of gas and seems the engine is getting a lot smoother. (My problem is since I just bought this I don't have a reference point to compare.) My mechanic pulled out one spark plug and said it was ok. I am going to go for the fuel filter (since the additive seems to be working) and throttle body next. Any particular cleaner brand I should look for?

  • Apparently this does not have a distributor!!!

    The distributorless ignition system used on these engines is referred to as the Direct Ignition System (DIS). The system’s three main components are the coils, crankshaft position sensor, and camshaft position sensor. The crankshaft position sensor and camshaft position sensor are hall effect devices. The camshaft position sensor and crankshaft position sensor generate pulses that are inputs to the PCM. The PCM determines engine position from these sensors. The PCM calculates injector sequence and ignition timing from crankshaft & camshaft position.

  • Guess what, the fuel filter is inside the gas tank and serviceable

  • I mean fuel filter is NOT serviceable

    locate the air filter.follow the hose about 4 inch diameter and it goes to the throttle body.undo the clamp,and pull the hose off. look inside the throttle body and if it looks dirty or gum or varnish,get a can of throttle body cleaner and follow the instructions on how to use it.

    good luck with it. i am on only once a night around this time,but will check back tomorrow...

    glad you are making progress.i would use the product that nissan uses.it is made by keyline.a nissan dealer will sell you some. if the air flow meter is telling the ecm (the pcm is powertrain control module) that there is more air it will add more fuel. the 3.5 is a dohc engine.the first run sold in the 300m,which is the same engine, had a bad camshaft and the cars were not sold until the cams were changed.the intrepid is 214hp and the 300m 250 and the 300m special 268hp.

    the ecm uses input from the iac map and airflow meter to determine how much fuel to use.

    the crank and cam sensors control the timing

    it is important to have a clean air filter,fuel filter, throttle body,a free moving EGR , IAC and no vacuum leaks.the vacuum leak will cause the idle to be a little high.the loaded rpm on that car is 675rpm a plugged fuel filter can burn out the fuel pump,by the way do not run below 1/4 tank...the fuel is used to cool the fuel pump.

Sparkplugs and wires-if your plugs are old then your car wont run good, becasue it will fool them.

get a good fuel injector system cleaner-these help by cleaning the fuel system and injectors giving you more mileage...

what brand of oil are you using, also what weight of oil are you using too. weight and brand of oil is vital.....cheap oil is not soo good....

bad compression all around cylinders......as engines get old bad milleage develops due to loss of compression.

JUST A COUPLE OF SIMPLE SOLUTIONS.....HOPE THIS HELPS XD

Hmmm...that is pretty low mpg. I believe it should be over 20mpg. I can help you though.....

Do the following....

1) Get a new battery. The one in the car is probably the original and on its last legs. Costco has great batteries at a great price if you are a member.

2) Replace the distributor cap, rotor, and spark plugs.


All together about $100 in parts if you DIY it.

    You have a pretty severe mpg problem. Things like changing the oil or using a fuel cleaner aren't going to do much for you. It could be caused by ALOT of different things. Nobody can tell you what it is exactly over the internet. You need to have a mechanic do a diagnostic on it. One thing to note is that if the problem is an emission control it may still be coverred by your warranty especially if you are in CA. Good luck.

It just depends on your tank size. You probably get about 15 -18 miles per gallon. 13 gallon tank would be around 200 miles. 15 gallon tank around 232 miles.

BAD ON GAS


You should be getting close to 360-390...depending on the type of driving you are doing. Increasing your gas mileage could be as simple as getting a fresh oil and filter job, change your air filter, change your fuel filter...and a biggie believe it or not, make sure you have the proper tire pressure. This will kill your mileage faster than anything else.

City MPG: 16-18 mpg
Combination MPG: 18-21
Highway MPG: Approximately 26 mpg

Poor Fuel Mileage 2006 Hyundai Sonata 2.4 motor


I don't know from where you bought the car but do you feel certain that typical causes such as fouled plugs or clogged air filters are not at fault?
Most dealers, even the shlocks don't normally skimp on the simple stuff but who knows about a private source?
That does seem low, especially the city numbers. I don't think Hyundai is any leader in gas mileage but they are better than what you are getting.
