Question about 2005 Dodge Neon

3 Answers

05 Neon Bogged Down

I was driving down the road at 45 mph and noticed some surging in the power of the vehicle. I stopped at a light, and when it turned green, I pressed the gas pedal and the car didn't move for the first 7 seconds or so, then started to creep forward. I gently pushed the gas all the way down, and the car was not going anymore than 5mph. It wasn't revving up either. It took approx 1.5 min to get to 40 mph, with the car verrry slowly gaining power. I needed to turn, stopped in the turning lane and waited for traffic to clear very far, and it was 'chugging' during the stop, once again creeped out into the intersection, and then it died. I threw it into neutral and started it back up, and creeped out of the intersection (without getting hit luckily). After I got out of the turn, the car gained power as normal and I continued on my way. It's done it much more mildly the last couple of days or so as well. I've got people telling me it's my spark plugs, catalytic converter, fuel filter, fuel pump, oxygen sensor, crankshaft sensor, or injectors, or a combination of such. The odometer gives no error code. What do ya'll think?

    Three weeks ago I changed the oil, air filter, and spark plugs (oh and did the brakes too). Should I go ahead and change the fuel filter?

Check the fuel pressure. If necessary, connect the pressure gauge to the fuel line near the injector rail and route the gauge so that it's viewable from the driver's seat. Drive the car until the problem re-occurs. Pay attention to the gauge while the problem is active to see if the pressure has dropped off. Service the pump and filter if the pressure is low. Be sure to thoroughly clean the tank before installing the new pump.

Try the a full tune up. Change your plugs, oil, and filters. Put in some fuel conditioner and try getting fuel from a different gas station. The fuel filter sounds like an inexpensive and important part of this equation. But try the tune up to whatever is cost effective for you. You should notice quite a difference.

    Yes, I would do the fuel filter for sure.

I don't recall if the neon has a distributor, but if it does, you'll want to do:

Air Filter
Oil filter AND oil
PCV valve

If this continues, you may need to do the EGR valve, if that doesn't fix it, you may have a vacuum leak.

The other solution is to try fuel that doesn't have ethanol, because Dodges are known to have issues with even the slightest bit of ethanol.

    You may also want to check fuel filter, and worst case scenario, you may have a blow head gasket, or intake gasket and it's sucking air.

    Not only is it Coil Packs as the ignition system, but Vacuum leaks, such as you are implying, don't all of a sudden go away and the car trots off as normal. and "DO" the EGR? you probably mean to see if it's seized open or shut, depending on the circumstances, and simply hooking up a scan tool would give you that information, as would watching the actuator, and hitting the cursed thing with a screwdriver carefully .your fuel concern is valid, providing that it had either been recently moved, or filled. also, every car performs worse with ethenol, if the engine wasn't specifically designed as a hybrid. what you said in your "solution" is to blindly replace every single part on the Engine that has anything to do with it running, without telling the complainent how to properly diagnose which peticular component OR system is being a nuisance. Seriously doubt your a dealership tech, your intake gasket is also false, becasue he CLEARLY states it is an intermittant issue, gaskets, especially that peticular one, don't "heal" while driving through the city to get you home. well done laddie, i feel comfortable knowing there is people like you on these forums.
