stalling problem with 96 dodge neon dohc

I have been having problem with neon stalling. I can drive around town but once i get on highway about 65 it starts jerking, the rpms start bouncing everywhere, service engine light comes on, starts loosing power and then stalls, I wait a couple minutes and it starts back up. I have replace the control module on top of engine, spark plugs and wires, cam sensor, fuel filter. Had in garge and wouldnt do anything for him. I picked it up and drove about 30 minutes and did it again with black smoke coming out back. Does anyone have any idea what it could be

sounds like your o2 sensor not very expensive and easy to change

replace the one on engine but not one on exhaust but not showing code for it. code i think was p031 control module or misfire

Correct me if I'm wrong here. You have an auomatic transmission and 65 moh translates into about 3100 rpm?

Is it possible to slide the transmission selector into "2" and cause the same problem at a lower speed but at 3100 rpm.

Or even in low"1" see if you can cause it to sputter.

If it does then the problem is engine speed related and not necessarily horsepower related.

Check it out it is an easy test.

I want to determine if it is fuel supply related or ignition control related. High RPM with light pedal uses les fuel. I'm thinking spark advance exhaust recirc.....
fuel pressure.

it seems be when driving normal. The last time it did it i drove a good ways and had to go up a good hill with the ac on and of course didnt have good power so pushed the gas on to get more speed. Once i got over the hill had a small hill to go up and it started in middle of that hill. Wasnt giving much gas for that hill. When it started a black puff of smoke came out the exhaust. I have taken to garge and them put it on computer but is reading control module or misfire. I am going today to auto zone for them to put in on computer and get the code for sure

I have taken to garge and them put it on computer but is reading control module or misfire.Which one is it? Have you retrieved the codes yourself by doing the key dance?

no havent done that dont know how

changed the air filter last night and wiggled a harness that is by the pcm.
Today the service engine light is off and i drove it for 2 hours at 65-70 mph and didnt do anything. It was a little cooler today it have been in 90's but today is in 80's

To read any OBD codes, perform the following sequence.

1)Cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds.
2)Count the number of times the 'Check Engine' lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. For example, flash-flash-flash [pause] flash-flash represents the code 32. The last code you should get is 55, which is end of codes.

To cycle the ignition key ON means to turn it only as far as it takes to get the dash lights to respond. It does not mean to crank the engine.

ok did the key dance and got code 12 and 43

ok did the key dance and got code 12 and 43

ok did the key dance and got code 12 and 4312 is battery disconnect within the last 50 key-on cycles, don't worry about that one. The 43 is a cylinder misfire, 99% of the time it's one or more spark plugs that need to be changed. Go get you some stock Champion sprak plugs from Autozone, O'reilly's, NAPA or whatever store you prefer and change the plugs. After that pull the fuel pump fuse out from the PDC for about 10 minutes, then reinstall the fuse. This will reset the computer. After that if you still get the code 43, then you need to inspect your spark plug wires and coil pack for any cracks or defects. In fact, check them when you are changing the plugs.

Again, buy the stock Champions, don't buy platinum plugs!

ok i did just put in plat plugs about month ago but was having problem before that. On wires should i get the more expensive ones or any will do and the control module i just got from auto zone a month ago too. That is what they said was wrong in the first place so got new one and two days later it was doing the same thing

im sorry the coil pack you are talking about i just replaced at auto zone they called it the control module

ok i did just put in plat plugs about month ago but was having problem before that.The problems you were experiencing before was they needed to be changed. Replace the platinum plugs with the stock champions. Platinum's don't help the neon in anyway and can actually affect performance. I would do that first before buying wires. I have Magnecor wires on my car, I got them from Modern Performance.

im sorry the coil pack you are talking about i just replaced at auto zone they called it the control moduleIdiots!

also could it be a short from the battery to the pcm that could be causing the misfire. I heard that sometimes battery acid corrodes (spelling lol) the wires

also could it be a short from the battery to the pcm that could be causing the misfire. I heard that sometimes battery acid corrodes (spelling lol) the wiresOnly way to tell would be to pull out the battery and check all the wires for corroding.

ok going to get them today i do know that looking though my book they gave me the wrong gap number too. they said .035 but in auto book says .050. dont know if can get same wires here that you have just have auto zone or advanced auto

thanks alot going to try that and will be back and let you know. of course i drove for 2 hours today and didnt do anything but i will try and see and drive it some more to see if that helps

ok going to get them today i do know that looking though my book they gave me the wrong gap number too. they said .035 but in auto book says .050. dont know if can get same wires here that you have just have auto zone or advanced auto0.035 is the correct gap. You shouldn't have to change the gap much, if at all. The wires from Autozone should suit you fine, I got the Magnecor wires, because they are guaranteed. You can order them from www.modernperformance.com. I think they close at 5 today and 4:00PM central time tomorrow.

It sounds like starvation under load.

hey just want to say thanks for the help. replaced plugs and wires, checked coil pack for cracks, put it all back together but not sure if still have the problem will see soon havent drove long distance for awhile. thanks again
