i will be driving either normal or aggressive and all of a sudden the check engine light will come on and the car will jerk llike it just stalled and start slowing down leaving the gas pedal useless. i have to turn off the car and restart it for it to stop doing that. the light will stay on but then go off after a few different times of restarts. then a week or two later itll do it again????
whats going on can anyone relate and help!?!

also i just added a cold air intake and was wondering about the driving in the rain or after it just rained, i dont have a flter cover just yet but is it ok to drive?

'05 Dodge Neon SXT (5-Speed)

your coil pack most likey i had this problem it was the coil pack

Mine was getting a bit rough lately and I have kept up on spark plugs and what not. I just added a bottle of Redline SI-1 and much better just needed clean injectors.
Easy fix for me.

perhaps you just need a quick tune up.

well i would try the injector cleaner first its cheaper then a tune up and if thats not it atleast you have clean injectors haha if not injectors tune up but most likely if the check engine light comes on its the coil pack

what kind does anyone recommendand would i need new wires and plugs?

i need to do one to but im waiting an saving up for msd :Dbut that me you might not want to just spend 75 just on the coil pack

is that like a high performance one? i saw them and they're red. got one in blue?

i dont think so all msd products are red

You can find a coil pack for the neons in blue, accel.

all the accel ones ive seen have only been yellow

whats the difference in all these

tns used to have the blue coil packs but i guess they don't any more.

whats the difference in all these

Basically the name brand and color they are both better than oem, but you won'tnotice a difference between an accel and a msd coil.

well which one is cheaper lol

why dont you go get the engine code the next time it does it... that could def. tell us what the problem is... i mean that is the reason they invented engine codes..... so yea

how do i do that? the turning of the key trick?

yup you got it!

do i have to wait till it does it again or can i do it while the check engine light is still on

I have screaming demon set up, coil and wires. I haven't had a problem with them. I've had them for three months.

the engine code is P 0340 which i found out is crankshaft sensor positionunit . . . . now what i heard it could be many things then just the sensor thats bad

Don't waste any more money on the Accel or MSD packs than you have to... there is virtually no difference between the packs at all. I should know, I used to make the Diamond packs (the stock OEM pack that came with your car). And they are very reliable and consistent, usually all posts firing at 43,900 to 44,200 volts. These values will not usually fluctuate either.

The MSD is virtually the same exact pack as what the OEM pack is... except it is red, has slightly less filler in it's potting mixture, and has the older-style brass terminal on the HV posts (most of the OEM packs after 2002 have steel posts, which have virtually no real performance change from the brass, just cheaper to make other than that no difference).

The Accel pack is (I think, not sure...) a Denso-produced pack. The Denso is of no higher quality or performance than the Diamond pack. I would just say that from personal experience, I question a lot of Accel's products and their quality standards. I usually stay away from them... their stuff just is not consistent.

Bottom line, if you have to replace a coil pack, keep in mind that there is virtually no significant difference at all between the performance of the OEM, MSD, or Accel pack. If you like a different color, then mask your poles and connectoroff and paint it whatever color you want. Other than that, they have virtually identical primary and secondary coils, and leads and connectors... other than the potting, there is nothing else inside of these packs, that's it. No circuitry, no ignitors. The OEM packs in the Neon are about as simple (and effective for DIS) as they get.

Bottom line, if you have to replace your pack, I would overlook the brand and just go with whatever is the cheapest. Granted, coil packs can and do go out from time to time, but the odds of having to replace one are pretty slim (when it comes to the OEM pack on the Neon)... a lot of this has to do with it's overall design. If you went to junkyard and found one cheap, I would recommend trying that as well. Chances are, a OEM Neon coil pack in a junkyard is probably 100% good, 99.9% of the time...

And just to top it off, the Neon OEM coil packs (and Caravan, Viper, etc) were made by Diamond Electric in Michigan... and when they were sold to Chrysler they had a 150,000-mile limited gaurentee on their performance. Just food for thought.

A 3 year old coil pack will not cause these problems. plugs 8$ wires if needed 40$ like new again. this will fix ur probs cheapest way possible it recently happened to me and my buddy on a 2000 and 2003 neon. Neon just love the taste of new plugs!

Word [sm=icon_rock.gif]

well i added new plugs and i still get the problem at times

I had the exact same problem.. If you have an ohm meter, check the resistance on your coil pack.

Primary Resistance (To computer):
Steel Towers - 0.45 to 0.65 ohms
Brass Towers - 0.53 to 0.65 ohms

Secondary Resistance (To Spark Plug Wires):
Steel Towers - 11.5k to 13.5k ohms
Brass Towers - 10.9 to 14.7k ohms

My primary resistance was completely out to lunch, so I just threw in a new ignition coil and a set of OBX wires, with NGK plugs a couple days ago, and she runs like a champ.

lol ya . . . well did u have the engine code for something about the crankshaft positioning censor unit???
