Engine dies while driving

Haven't been to the forums in a long time. Good to see that it's still going strong.

I am having an issue of of the engine dying while driving.
Is there anything easy I can check on this?

Sometime all the warning lights go up before the engine dies. If the fix is too costly I am probably going to have to trade it in.

Anything obvious I should check before taking it into the shop? The fluids all look normal.

Alternator.

Does it start right back up?

Does it have to be jump started?

It starts right back up. When it happens, I turn on my hazard lights, put it into park and restart it with no problems. The negative battery terminal seemed loose a few days ago, so I made sure they were tight and non-corroded.

Any stored ECU codes? Possibly a cam/crank sensor or even the MAF sensor.

Alternator, battery or wires in between.

had same problem. CHECK THE FUEL PUMP!

I had the same problems and replaced my maf, twice. It still died at stops.
I still haven't found a cure for this problem anywhere on this board yet.. it must just be the nature of the beast.

Codes that came back after clearing:

34 EGR solenoid valve EGR solenoid valve inoperative.
37 O2 sensor 2 (LH) O2 sensor 2 inoperative.
23 Air flow sensor Abnormal voltage from air flow sensor.
56 EGR system (CAL.) EGR calve open/close stick, EGR hose disconnect or exhaust pressure valve damaged.

I had code 37 and 23. I noticed a small hose missing under the intake line, I replaced it, cleaned the MAF and replaced the PCV valve. I cleared the codes and they never came back. You might also have a vacuum leak or an obstruction somewhere.

All of these indicate that the ECU, the fuel computer, is getting wrong readings and can't control the mix to give the optimum stoichmetric burn.

Worst case scenario, all four are bad and need to be replaced.

However, since you have already been advised that the MAF can give the symptoms you are getting, it's an obvious place to start.

Money for parts might be an issue, but it is unwise to drive what is an expensive car, and do nothing about the trouble codes it gives you.

If you have a friend nearby with an SVX, a non-expensive start would be to borrow the MAF from the good car for 20 minutes. Clear the codes and bolt the good MAF into your car. After a drive if it comes back with some or all of your other 3 codes, then you may need to investigate them and replace what is necessary. I would bet if the MAF readings are primary cause of your trouble, the two O2 codes may go away when the MAF is replaced.

Best of luck checking it.

I am having the same problem. car stopped in the middle of the road , but restarted without a problem. A few weeks before it was starting on 4 cylinders every day, had that rectified. But the engine light came on yesterday and its in the garage. They say they can't find anything, and asked me if I could show them what happens. I told them to take it for a drive and find out for themselves. As expected nothing happened.
