My van won't start after driving a short distance, it will start again after 3 to 5 minutes but then will act like it's going to stall while I'm driving. What's wrong?

Hi Greg, I'm AL the owner of Big As Auto Repair in St Charles Mo

Greg, I read your complete message, but nowhere did I see that you replaced the Cam Sensor. The EGR will cause it to stall at stops but usually will not prevent it from restarting. I would try replacing the Cam Sensor before anything else. If you should need further assistance go to my website by clicking here: Auto Repair

I had a customer buy an 02 cavalier from me. About a week later they called me saying that their car wouldnt shut off and they couldnt turn the key back. To get it to turn off they turned the steering...

If the key and switch are now turning on & off properly, does the starter engage & crank the engine? If it does, have the key & lock cylinder checked by a locksmith, or mechanic with the needed diagnostic equipment. The cylinder reads the key and tells the computer that the car isn't being stolen, activating all the other systems. If this is the problem, it will require removal of the air bag & steering wheel to be replaced.

Engine skip

Before it is warms up- the pcm (computer)
controls the injector timing

Once warmed up- it is controlled by the oxygen

If you have not replaced the front or upstream O2
Sensors do that (usually they fail at 100,000 miles-
in your case you have too many years on them)

You do not need to add anything to your fuel,just a waste
of money to add a few oz in many gallons of fuel,won't do
a thing -although Chevron is supposed to be the best, if
you do use any

You may have ignition coils going bad & the place you went to
most likely just installed spark plugs, etc & never road tested
or diagnosed all the data avail to them or anything else

All too common to waste money at these shops now adays

Pretty much have to tell them how to do their job, if you want
things resolved or keep trying to build a better relationship with
a good shop,never go to the chain store places

You going to find after driving 20 miles or more that the ignition
coils break down & do so in no pattern
You can go 2 weeks or have them fail at every traffic light one day
& then nothing for another week
You can drive for 200 miles at 65 & then pull off the highway & it
shuts down,two days later the problem is back
Always bad individual ignition coils on a ford

Truck shuts off while in park idling.

Your car is 18 years old. It's likely history. Sell it as is for what you can get.

Tucson 2009 dies mid drive

The possible CAUSES of the problem you describe are NUMEROUS!.. You may have what the industry calls a 'LEMON.' There is a LEMON law in every state. Sinse it's a 2009 model, keep at them (dealership). Warranty procedures APPLY! You may not like it, but you are covered under WARRANTY!.. I'm sorry, but under the warranty agreements between Hyundai Motor America and the Dealerships, you are relegated to KEEP AT them.The most difficult problems/malfunctions to diagnose are those which DON'T STAY BROKEN! Tell you what, since you posted your problem here, you'll have to do some homework yourself (become a Hyundai Certified Technician).. then you'll see how DIFFICULT the diagnosis can be. Walk a mile in the technician's shoes! Sometimes the problem can simply be a resistive/poor ground
circuit, OR, could be potentially a multitude of different problems. Take/tow the vehicle into a Hyundai Service Center (dealership), Insist they find out what the problem is!... Then you'll have the option of having them buy it back under the "Lemon Law.'
