Question about Dodge Neon

1 Answer

My 2002 Dodge Neon has been have a hard time starting every day, and recently it's been stalling at stop lights. I push down on the gas, but it takes almost a good minute for the car to get going, and when it does, it sputters. Now, the check egine light is on. It reads misfire 1 & 4, my brother replaced all spark plugs and I bought a new ignition coil today and he replaced that for me. But the issue is still existing. Can any please tell me what more we can do, or what exactly the codes mean for misfire 1 & 4? Thank you so much for your time!!

Sounds like you are having trouble with the fuel pump on the car. Not enough fuel pressure to the injectors causing the car to sputter and die. If at all possible check the fuel pressure at the fuel test port on fuel rail, or if no test port will have to disconnect fuel line on passanger side of car next to firewall. Squeeze the connector clamp on hose to release it and hold it away from yourself and just turn on the ignition. The fuel should come out at a good force, if not the pump is at fault. On the test port if you have one use a fuel test gauge and the pressure should be about 53 to 63 psi. The codes for misfire on engine are #1 misfire po301 and #4 misfire is po304. Hope this will help you.

Why wont my car accelerate?

If you have an overdrive transmission the direct drive clutch may not be releasing. Have the trouble codes read to see if the computer or a sensor is starting to fail.

2002 neon died going down the road doing 30 mph.won't do anythig.have lights but oil light won't come on when you turn the key.battery seems fine

I also have a 2002 neon and a few mo.s ago it shut down. A mechanic told me it might be the fuel pump. He suggested taking off the breather cover and take out air filter and spray starting fluid toward the intake. Sure enuf it started. The next day I towed the car to the mechanic and brought a new pump and later was good to go.

I have an 2001 dodge neon, When i got it, it drove so good and now every time i try and start my car it has a hard time running and when i push on the gas pedal it sounds like my car is getting flooded or...

May have a few issues here. The first is a possible vacuum leak. Vacuum leaks are so broad though. You'll need to check the entire intake for rotten hoses. The hard start could be a bad fuel pressure regulator of fuel pump. Along with that. The Fuel Pump could be related to more than one of those problems unfortunately. Another thing could be the Throttle position sensor not getting the propper voltage to allow for smooth running and acceration. Does the car have a check engine light on?

Dodge neon gas pedal problem

Not sure what spring you're talking about with the CAI. The CAI is just pipes and hoses, there shouldn't be a spring. Have you driven another 2002 neon before? I know with some cars, the gas pedals are a lot stiffer than others. My gas pedal on my Focus is a lot stiffer and more sensitive than my friend's aveo or civic. The spring I think you're refering to is probably the one hooked up to the pedal itself which is easy. Just pull out the old spring and put in a new one.
