wont stay running

S00K · Feb 15th, 2004, 06:12 PM

For my dads 97 Jeep Cherokee 4.0L, the car will crank when i try to run it but wont start. If i tap the accelerater pedal a couple times it will start and if I hold it to about over 1k rpm, it will stay running but as soon as i let off the acc., it will shut off again. And also the tailpipe blows white smoke and lots of mist.

I know this isnt nissan related but didnt know where else to ask. And if this is in the wrong section plz move this.

Thanks for any help.

Check the MAF sensor on the intake
