2002 saturn vue v6 3.0 AWD it shuts off while driving,but starts right back up.drive a little and it shuts back off i replaced crankshaft senser


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

2004 saturn vue at low speed engine rpm up and down


I have the same problem with my 04 v6 awd vue.
The issue i see is with the transmission torque converter going in and out of lockup consistently. I have noticed when i engage cruise control this problem goes away for the most part. Today i turned on cruise at 30 miles per hour after noticing the rpm fluctuation about 400 rpm. change to only about 100 rpm. This has been an issue scene day one from the dealer. no codes, the transmission has not failed nor the torque converter. I think it is an issue with the drive by wire system. when you engage cruise control the foot throttle position sensor is out of the equation. This is my best guess, you can take it with a grain of salt.

Engine noise that makes my 2002 Saturn Vue V6 AWD sound like a diesel. Could it be a rocker arm that needs adjustment? If so, what repair cost am I looking at?


it could be a rocher arm, or it could be the timing chain tensioner, mostly it the rocker on those they make it sound like the motor is going to blow, to have the rocker checked and adjusted i beleive is about $180.00. good luck.

2002 Saturn Vue V6 AWD sounds like an F1 car when i drive it. Very loud constant noise. Checked trans fluid and it was fine.


I have a 2002 saturn vue. Same thing..sounded like a jet engine ...loud humming as I accelerated . It got increasingly worse. It turned out to be the front wheel bearings. Replace them, now the noise is half as loud...have to do the rears also! 93,000 miles on it. Also, don't forget to replace the timing belt. It it goes too long and breaks, it will trash the engine...

Under the intake manifold,  it will need to be removed.  Not too hard to do for the average diy but recommend buying a repair manual as a guide.  you will need a 1/4" drive T30 torx socket with a long extension one of the bolts is hidden but the others are under the black cover on the top of the intake.  you will also need to remove the coil pack held on with torx bolts.  8 or 10 inverted torx socket needed for that.
