Same thing happened to my 1995 Dodge Neon. I changed the thermostat, then the water pump and timing belt, then the radiator. I ended up selling it because I thought it had a bad head gasket, however, it ended up being something to do with cracked pistons or something. The guy I sold it to fixed it and is still driving it today, so I would have a mechanic look at the pistons.

#60 of 90 Engine starts to missfire as temp reaches normal by neongreg

I have a 95 Neon SOHC, bought new, now with 126K miles, and I have just begun to experience this problem. When I start the engine, it runs smoothly until reaching normal temperature and then the engine starts to missfire, surge, sputter, and eventually shuts down. It took me 6 tries to get my car home as I had to let the engine cool between each run. I just replaced the Mopar HP PCM that I installed a few years ago, with a new one. I replaced the waterpump a few years ago and it seems fine. I ran my analizer on the engine and it gave me cam sensor, crank sensor and coil failure codes, but the coil is an MSD that I installed less than a year ago, and the engine runs smoothly until the temp reaches normal. I would think that a bad cam/crank sensor would cause problems from inital startup and not just after warmup. I have not pressure tested the cooling system lately, but I smell no coolant and see no leaks. No indication of a bad head gasket (original) but I have not pulled the plugs yet. Could the O2 sensor cause this problem after heating up? I also replaced the thermostat 2 years ago, but if stuck, would this be a possible cause? I would appreciate any help!

I had been having problems with my 2004 Dodge Neon with just under 70,000 miles on it. Of course I've taken it in several times with the "everything's fine" response. It idles funny when stopped at lights, and sometimes the "engine jumps" (the best way I can describe it). when I'm driving, the engine randomly "jumps", and when i pull in and out of parking spots, it's almost like the engine hesitates. About a month ago it started overheating... I took it in and was told that it was the headgasket. They replaced my headgaskets, timing belt, and crank shaft ring. It ran smoothly for about 2 weeks. The new timing belt noise didn't go away, so they told me that I need new "bearings" for the timing belt. Was told it wouldnt hurt the car to wait (until they found it used instead of $300 for new). But the car started doing all the same things again! Then yesterday, it overheated again. The mechanic "can't find anything wrong" - any thoughts??

the speedometer is a typical thing that goes wrong with these cars. you gotta pull the gauges out and re-sotter the pings. it will fix the gauge problem. also, your car isnt gonna have spark after the car overheats, its the pcm doing it to save the engine from further damaging itself. it should start after it cools down a bit.

usually its down behind the fans on the passenger side. you can go get a manual from the parts place for about 11.00.

#68 of 90 1997 Dodge Neon Overheating by beauds

Oct 24, 2010 (8:21 am)

Where to start, I have a 1997 dodge neon and something is defiantly not right. If i have my car on for about 10 minutes my temp guage will start to rise, and eventually will be at H, but then it will slowly randomly spike back down to mid, and then spike back up again, back down, back to H, and so forth..If i turn my car off with it being all the way at H, and turn my car over to just the guages having power, or even being all the way on, the temp guage goes to about mid. If i leave the car off for awhile, the engine cools like normal. Ive tried replacing the whole cluster unit, and also tried re soldering my old one. Didnt fix it. Since ive noticed that when the car goes to H, my radiator fans dont come on, nor do they ever, thats a problem it self. Also i just replaced the radiator cap and thermostat. When the car goes to H, the therm. doesnt always open. The other day i was letting my car idle and i saw smoke coming from my hood, it was only coming from the side where the overflow tank was and the radiator res. is. And i drove it home quickly to find out all my anti freeze leaked out..weird back pressure perhaps? I told a guy who works solely on neons the symptons and he thinks its a headgasket, anyone else have any ideas?
 
Thanks
