my van is not starting right when the engine is hot.acts like its starving for gas/not firing.say I drive it for 30 minutes,then turn it off,and 5 minutes later try to start it again,no luck!you can pat the gas to try and keep it running but that dont work,it just sputters and pops...its also starting act cut out while driving it.put it on a machine at local parts store and it read,SYSTEM TOO LEAN BANK 2.possibly an o2 sensor.? looking for advice on this before i go blowing $ on parts that i dont have to waste.hoping i could fix it myself and save a little... any help is greatly appreciated!!! thanx JT :thumbsup:

guessing no one knows? :eek7:

system too lean bank 2 is what comp says?what could that be and where is bank 2?which side if the engine?was told it could be an o2 sensor,but could the coil possibly be getting hot and having fits? hope this helps so i can go get whats needed to fix! thanx jody
oh yeah,theres 2 o2 sensors, @ $130.00 a piece,need to know which one to get if thats it...

Bank 2 is passanger side.

i put the downstream o2 sensor in it last night,seems to be a little better,but its still acting up a lil bit like i said before.could it need the upstream o2 and possibly plugs?or maybe stopped up cat converter?thanx for the response!!! :bigthumb:

Bank 2 is passenger side? On a transverse mounted engine?

Since the engine only has a pre and a post, they have to be bank1sensor1(pre), bank1sensor2(post)...customer is mistaken....wonder if it's even a hard code or history....

Could be any number of things, but doubt it's an O2 sensor, on start up.....could be ECT sensor, vac leak, MAF sensor, F/P reg leak, etc.
