Engine starts then dies.

I had this problem and it was a vacuum leak I found by using this guide.

Went out to warm my S40 up this morning and the car started fine. On my way back in the house for the coffee, the car stalled. I went back to restart and all it did was turn over. No prior warning something was wrong. I pulled 2 codes. P0508 ( Idle Air control system Low circuit) and P0015 Cam position B Timing over retarded bank 1.

Everything I have seen here regarding Idle air control valve is the car will start if you depress gas peddle, not mine. Any help will be great!

Timing belt is new, I did the work. Oh no! I did look at it mark or left gear 12 o"clock, mark on right gear not quit at 12 0"clock but about 1/8" before 12.

Is there another mark on the crank? How do I see that?

Timing seams to be correct. I am in question about the belt tensioner, I'm wondering if this is correct. Could this have loosed?

I have a 2002 S40 turbo. Recently, the electrical system starting doing strange things. First the radio would just change stations or get loud.

Then some of the "idiot" lights would flash on and off.

Now when I come to a stop, the car randomly stalls. All the dash lights will go off and then come back on. There is no warning. When I try to restart the car it is completely dead. I don't even hear the clicking noise of the starter trying to turn over.

After turning the key several times or trying to put the car in nuetral, it will start.

I have a mechanic looking at it and they have not come up with anything when the run the diagnostic tests and they can't recreate the problem.

Another thing, the positive battery cable seems to be hot as the insulation around it is discolored. I put two new batteries in the car in less than 2 yrs. When I had the car serviced, they said the current battery needed to be replaced.

Stumped in Memphis

Hi I just bought a 2002 s4o volvo with 61000 miles on it about a month ago and I havent had any problems. On my way to Orlando Friday I was getting on the highway adn when I turned it just stalled on me like quietly shut off. I almost got rear ended! It does this when I am driving slow and turnign at the same time or if I am just sitting at a light. It idles a little bit and then shuts off. Other then that It's fine. SO I just recently had it hooked up to a computer and FIXED AND THE PRINT OUT AND CODES I GOT BACK WERE

P0101- MASS AIR FLOW SENSOR
P0102 - BOOST PRESSURE SIGNAL TO LOW
P0301 MIS FIRE CYL #1
P0302
P0303
P0304
P0131 FRONT OF SENSOR SIGNAL TOO LOW
AND LAST CODE WAS
P0107 AND THAT NEEDS FURTHER DIAGNOSIS HE SAID

HE SAID HE CLEARED MY CODES, REPLACED SPARK PLUGS, REPLACED AIR FILTER, AND CLEANED TROTLE BODY. THAT COST ME 177.26 AND THAT SHOULD FIX PROBLEM.
ALTHOUGH! ITS STILL SHUTING OFF I AM A COLLEGE STUDENT AND NEED OT GET BACK AND FORTH FROM SCHOOL I CAN'T HAVE MYC AR STALLING DOES ANYONE HAVE ANY SUGGESTIONS OR KNWO WHAT I NEED TO DO! THANK YOU SO MUCH kristinmcd19@yahoo. Com is my personal email
