Asked by May 19, 2013 at 09:53 AM about the 2003 Dodge Stratus SE

Question type: Maintenance & Repair

I have an '03 Dodge Stratus with a 2.4L that was running a little rough with only 47k miles
on it. I changed the oil & filter, replaced the spark plugs with NGK plugs and replaced the
oil filter. I started it up and now it's idling about 3,000 RPMs and will not kick down at all. I
pulled the air filter back out and checked all the connections and that seems okay, but
the idle will not kick down. Does anyone have any ideas?

Edit: Don't know how to edit my post. I replaced the oil & filter, spark plugs and air filter. I realized I posted oil filter twice. Sorry for the confusion.

Sorry, I am coming up empty on what the problem with your car is. Chances are somebody else will have some ides, But to edit you post, highlight it, copy and paste it in a new "Your Answer" box, then you can edit as necessary, re post it, then delete the old one by clicking on the little triangle arrow in the upper right of the box with the answer in it, click 'delete post', you will get an "are you sure.." click 'yes" and it will be gone

Double check that the air filter box is completely closed. Check for any vacuum lines that might have come undone during the tune up. Check maf sensor is plugged in securely. Also is your cel on?

I disconnected the sensor on the hose for the air filter when I changed it. I read on another post that it might be the problem. The post said to disconnect it and if your idle drops that's the problem. So to answer the question about the CEL, the light was not on until I disconnected that sensor and also the idle did not drop when I disconnected it either. So now I have the high idle still and now the CEL is on from me trying that test I read on another post.

Un hook your battery for about ten minutes and that should reset your cel. Was there a high idle before you serviced it or just after? If only after I still thinking a vacuum issue.

Had a rough idle before the tune up. The high idle only started after tune up. I checked everything I touched and I can't find anything wrong. Tune up if fairly easy on this car and doesn't require touching much that you are not actually working on like some vehicles. I am thinking I might of did something or touched something that might of been causing the rough idle I originally started with.

That looks different. My throttle body is in front. The PCV is on the drivers side of the cover, the spark plugs are right on top thru the valve cover towards the rear of the engine, the air filter is where the battery would typically be located and let's not forget that the battery is actually in the front bumper below the drivers side headlight on this car.

Oh ok. Check any electrical connections that are anywhere near where you were working. Don't unhook them just wiggle and push in just incase one is loose. Specially around the throttle body.

I only disconnected 1 electrical connection replacing the air filter. I have already triple checked that connection and I've already been wiggling all the other connections and checking the vacuum lines although I only disconnected 2 to change the air filter. I am thinking I aggreviated the real problem that was causing the rough idle and now I have this high idle as a result. But in any case, it started raining here about an hour ago, so I am done working on it today.

When I changed the air filter a piece of plastic from the sensor broke off and fell into the throttle body and got stuck in the AIS motor. Pulled the throttle body apart and removed the broken piece and had to replace the sensor that was in the air cleaner hose which is where the plastic piece came from. Hope this helps.

What did u gap your plugs at? The book and the label under hood says .050 but most forums(including auto zone) suggest .040 which has worked great for me:-) I've changed out the coil, boots, IAC, camshaft sensor, map sensor, pcv valve, plugs, air filter and the grounding strap and clip behind the head only for it to randomly go into limp mode on me with about a month in between episodes....grrrr..

You could also try switching out your throttle position sensor
