Vehicle engine running ok, no noises, misfiring, no shuttering it just shuts down. has happened 3 times in last week. hard to restart and when restarts have multiple misfirings. The TCS and Slip warning lights come on. Misfiring continues until speed exceeds 10mph but engine feels like has a loss of power. under 10mph and at idle have misfiring, but put trans in neutral misfiring seems to cease. tack jumps around only when this situation occurs otherwise tack works fine. do not know what causes the shutdown of engine or the misfiring. I live in Arizona approx. 40 miles south of Phx. I do not know what the engine temp is when engine shutdown occurs do to temp LCD not working. With physical observation engine does not seem to be overheating. Please advise if you can. engine milage approx 130,000 miles odometer LCD also not working. Engine is a V-6 3.5 cu in. coolant level, oil level, and trans level are all full and fluid is new to fairly new. Vehicle recently had new timing chain and water pump installed.
Intermittin Engine Stall
Engine No Start
Missfire
MISFIRE IN motor cylinder is more likely the cause to engine stall and hard start.
You will have to fix this problem first,
A misfire, most the time, is caused by, incorrect cylinder firing order (diagram at bottom). Or no or low cylinder compression
no or low compression is the result of A Vacumm leak.
If the timing chain was recently replaced, the valve cover had to be removed, the valve cover gasket could cause a huge vacumm leak which would effect some if not all 6 cylinders,
Symptoms
Lack/loss of power
Hard start
Engine hesitation
For Now
check firing order( coil pack to sparkplug)
check sparkplugs
NISSAN 3.5 V-6 FIRING ORDER
SPARK PLUG GAP 0.050''
SPARK PLUG TORQUE
COIL PACK LAYOUT
I hope this helps for now

You have a new radiator and thermostat, so your coolant was flushed. Was the radiator "burped" afterward to get rid of air bubbles? If not, that needs to be done first - it would explain virtually every symptom you're seeing.
Jack up the car so that the radiator cap is elevated. With the coolant
topped off, start the car and let it run until it's about 3/4 of the
way to overheating. Then shut it down and go have a beer. When it cools
off enough to safely open the radiator cap, do so, and any air trapped
in the system will bleed out.
What you're doing is circulating
the coolant and the air bubbles inside. The bubbles get lodged behind
the thermostat and stay there, keeping it from opening (this causes the
car to heat up). When you later pop the cap off the radiator, the
pressure is vented from the system, the thermostat opens, and the
bubbles pass through. They'll work their way to the radiator (since
you've got it elevated) and pop out the open cap opening.
Your
coolant level will likely drop somewhat after doing this, as the air
bubbles will be gone and the space they took up in the system is now
available. You may need to add a little more coolant, so top if off
(with the car back on the ground) and recap the radiator, fill the
overflow to the marked point on the tank, and you're good to go.
Try this if you haven't already, and post back up with your results. If it doesn't solve the problems, we'll take it further.

Hi,
Sounds like the radiator fan is not working. Or if it is and it uses some sort of clutch, then the fan air is not sufficient to cool the radiator. To verify, pls jump/hardwire the radiator fan temporarily to be always on with the engine running. this would mean providing a direct connection to the IGN B+12 and the other to the ground. Try, if it still overheats, then problem is elsewhere; if overheating stops, then it cold be;
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.

It's your MAP, MAF OR TPS sensor Do you have a check engine light?
SOURCE: 1994 Nissan Altima Stalls intermittedly at startup
tell your mechanic to look up Service Bulletin #96-032 this could fix your problems
SOURCE: service engine soon, TCS off, SLIP
The oil change wouldn't cause this problem. Just in-case, check the engine oil level.
There are many emission sensors in the car that will make the engine light come ON. Best way to find out what's going on is to have an auto-parts store hook up a engine code reader and tell you what the code means. Most auto-part store will do this for free.
Testimonial: "very helpful. i have the mechanic checked the car , the sensor says it has a malfunction in P0340"
