2005 dodge grand caravan stalling when you put it in drive but not reverse. The van also runs ruff. Trouble codes are as follows p0404,p0300,p0403,p0406,p0344,p0339,p0335,p0108,p0700,p0344,p0339,p0335,p0882. Replaced the cluster because friend had same problem with his van. If you pop it in drive with your foot on the gas pedal it will drive. what do you think

Have catalytic converter checked

run fault codes to determine which sensor has failed.

check the exhaut may be plugged

Maybe something wrong with neutral switch? Usually it is on or close to transaxle shift lever, follow the shift cable to shift lever, the switch has multiple wire connector.
It may be possible to start vehicle by jumping the load side of starter relay, key on. There are safety issues trying this, the vehicle will crank in any gear. Make sure tranny is out of gear, parking brake is set, block the wheels, whatever it takes to be safe, safety is your responsibility.
If the problem isn't that neutral switch, then I don't know? Any applicable trouble codes?

have the fault codes read first as the current problem as with the first has nothing to do with a torque converter
more like vacuum leaks , injector problems , low fuel pressures

most likely ur mass air flow sensor is dirty or faulty and or check for a vacuum leak down stream from the mass air flow sensor

Im assuming it is an engine that uses a timing belt. It sounds like the belt has jumped 1 tooth. if it only jumped 1 tooth than the computer will compesate the timing so it is possible the sensors will say they are ok. If it is a motor that uses a chain than it problaly needs a new gear/chain set.

Check MAP sensor. If PCM gets wrong data from MAP sensor it should offset ignition timing and/or make fuel mixture too lean or too rich.

3.3 and 3.8 engine pcv valves are it the rear head valve cover. they are a pain to remove

When the trans. sticks itself in 2nd gear and stays there is because it's detecting a trans. problem and puts itself in "limp in" mode. When it happens again, to somewhere to have a scan done on the trans. so you can find out which sensor on the trans. is acting up.
