Why does my 2002 dodge neon idle rough when cold any other time runs smooth ?


Sounds like it just is not getting enough fuel when cold. Try using a bottle of injector cleaner from the Dodge dealer. Make sure it shows naptha on the label and do NOT get any on the paint.

If that doesn't fix it be alert to temporary rough idle when stopping at stoplights. That will indicate you will need to have it scanned.

96 Dodge Ram 2500 5.9 runs ruff a low rpm has a p300 p302 p306, p307 adn after about 1200 rpm the misfire goes away and runs smooth psi on # 2,6 is 147 and #7= 30 psi, I changed the ecm, new plugs an


Something like that is sure wrong in #7. If you do a leak-down test, it should tell you if it is an intake or exhaust valve losing compression, or exactly what it is. A bent push rod would be a blessing. Then maybe you wouldn't have to take the head off for repairs. Roll a push rod over a glass surface to check for straightness.

Rough idle on 2002 Dodge Neon


Without trouble codes you are fishing in the dark. If the engine has a cylinder that is dead at idle from a fuel injector or ignition problem, it should have a code for a miss on that cylinder. A mechanical problem like a burned valve could cause the problem without setting a code. Have you checked compression on all 4 cylinders ? ?

Ran it 1.5 hrs idling now chugs at low rpm


This may be due to a dirty throtlebody or bad idle air control valve, using crab cleaner clean the butter fly plate or also called the throtle body plate, spray area and clean with a toothbrush and this cleans it good, make sure to open the plate and clean both sides and housing, when restarting you may need to hold gas pedal down to get it going and clear it out, with thew engine running spray cleaner into the idle valve hole, rais eidle a little and spray a few times, the last thing is if the low idle is due to a misfire like its skipping then you may have a bad wire, (sparkplug wire) but clean throtlebody also, hope this is helpful to you and good luck.

Starting a 2002 Dodge Neon in extremely cold weather


The best is to turn the key on to the run position for a few seconds then back off then back to run and then start. This cycles the fuel pump and sends a good supply of fuel up to the injectors. Also do not rev the engine excessively until it has warmed up to allow oil to flow good.
Good luck, dont forget to rate.

Car shakes at stop signs, very poor gas mileage, and sputters whe


Try having your fuel injector cleaned, you can start with running fuel injector cleaner though your gas tank and if that does not help then you have to get it cleaned out professionally or even worst have the injector's replaced if they are bad.
The other thing that will give it bad fuel would be a bad air intake temperature sensor go bad, as for the ruff idle that is common to a dirty or stuck EGR valve.
Good luck and keep me posted, by the way, what kind of Garage did you take it too? And are there and DTC codes from the ECM?

Car won't pick up speed on acceleration


You're not getting enough fuel. You should check your fuel pressure. If you have enough fuel pressure, your injectors are probably clogged up. Run a lot of fuel cleaner through your tank when you put gas in and see if it makes any difference. Lucas fuel treatment is the best to use.

2005 dodge neon throttle body sucks air until car warms up.


TRY SPRAYING SOME CARB AND CHOKE CLEANER INSIDE THE THROTTLE BODY WHILE WIPING IT WITH A CLOTH RAG. PAPER TOWEL WILL NOT BE STRONG ENOUGH. IF THIS DOESN'T SOLVE THIS THEN CHANGE THE IDLE SPEED SENSOR. HOPE THIS HELPS. BEST OF LUCK. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. PLEASE KEEP ME POSTED.
