I know this question has been asked a thousand times before but I'm tired of looking for six year old answers.

I bought a 2001 neon for my daughter that has seen better days. One of the most recent problems it has presented is vibrating when the car is stopped...like at traffic lights. The longer the car stays idle the worse the vibration gets. I've had two of the motor mounts replaced and those didn't seem to make any difference on the vibration. I cleaned the IAC today and no difference.

Can someone start throwing some suggestions my way. I'm looking for DIY things first.

Thanks up front!

 

Hey, I just bought a 2004 dodge neon sxt. When I first test drove it everything worked and sounded perfect. Well I've had the car for 2 days now... and the check engine light has already come on. And sometimes when I'm driving, if I let off the gas and get back on it, it starts to sputter. (that could be water in the gas tank). However if anyone knows if there could be anything MAJOR wrong with it.. please let me know!!!

 

thanks for nothing, I found out that it was the 02 sensor

 

Good site thanks

 

Stuck in the country with no one to help change the main belt on my 2003 Neon SXT. What tools am I going to need to do it myself? All I can find on here is gen 1

 

you were kinda on the right track but you only fixed the symptoms not the problem the 2 "mounts" you replaced actually held no weight they are there for torsional stability if you look where your timing cover is you will see a black object embedded into your frame it only takes four bolts to take out but you need to carefully lift the engine a little bit for clearance this is your actual weight bearing motor mount.the strut mounts went bad because they werent supposed to carry the weight they were carrying you might notice a vibration in your steering wheeel after you do this because you need to adjust the engine in the cradle to the right spec which is 119 mm away from a certain part i dont remember which one though. Hope this helps!

 

Did you get an answer for this one? I'm having the same problem. There is a syncro kit in the trans, but i wanna make sure its that before i dig into it and dish out money for repairs

I just found out today about this code on my car. I spoke with my mechanic and after the sticker shock of how much it could cost me, I am wondering if its worth fixing? And then he tells me it all depends on where the solenoid is located in my car it could cost me more (due to time and labor). I am not a motor expert but definitely need advice from other neon owners. She's got 124k miles.

 

2005 neon xst no crank problem. Very intermittent most prevalent in the morning and after sitting for a while. Can turn the key a dozen times with nothing happening and then all of a sudden it cranks over and starts right up runs no problem no check engine light. The things I've done trying to track down this problem i.e. jump starter at solenoid it cranks no problem does not change the problem with the key, this kind of indicates the starter is probably okay. If the ignition switch is on and engine is not turning over if I jump the starter solenoid it cranks over but will not start. Kind of indicating to me the same circuit that operates the starter also operating the fuel injection system. I have cleaned and re-crimped as many grounds that I could find in the engine compartment i.e. main negative battery to starter bolt from there to bottom of battery box. Ground from battery to fender well, both left and right grounds to the radiator support. Positive battery terminal to fuse box and also to starter. Of course both battery terminals themselves. Swapped out starter relay,checked fuses inside and out. Checked neutral safety switch, switching from part to neutral has no effect and the plug was clean and dry. Checked the harness directly above battery that has starter solenoid wire again the plug is clean and dry. Disassembled ignition switch cleaned and re-grease contacts again no joy. Of course the problem being so intermittent after doing a few things it will deside to start starting LOL
The harness on the backside of the engine feeding the alternator and oxygen sensor shows signs of some signs of heat damage from the exhaust system but I don't think that's where the problem is either. About the only thing I have not done is to pull the PCM and check the harnesses. Does anyone know where the PCM gets its ground from?
I have read as many of the comments I could find online and tried just about everything. And I see this is a common problem as far as the intermittent part people taking their cars in and having them check out the problem goes away for a while and comes back just the same. Sorry to be so long-winded just trying to be thorough thank you for any comments and please any help. The battery is new and has a good charge Thank you agian Jeff
