My 03 neon sxt runs like crap It has absolutely no power runs rough misfires I changed the spark plugs and it ran good for 1 day I also changed the air filter It stalls shudders and sometimes dies Help

 

coil or plug wires? Do you have any codes

 

P0340 P0440 P0038

 

Check them out in order. Solve the first code out first always. So you have a CAM sensor Circuit problem. Check make sure you cam sensor is plugged in and then probably time to replace it. Clear codes and go on.

 

where is the cam sensor on the car

 

my 2000 had misfire problems and it turned out to be the wires

 

the cam sensor
on the driver side of the head it you have too move the wiring harnes and all those hoses too get too it

 

first, try plugs & wires and coil.

edit:
when my srt had some rough running problems, it would run rough, lost power and would cut the rpms and sometimes overrev the motor without hitting the gas. it turns out the throttle positioning sensor was out of range, so the car's computer got 'confused'
