Engine turns off when hot

I have a 2002 c240. I just had the MAF sensor replaced to fix a po171 code last week and now when the car runs for 20 minutes or so it turns off and does not start back until it has cooled. is it the fuel pump or the guy who replaced the MAF has mess something up?

    C240 has shut down once while running, unfortunately in a McD's drive-thru. More often it will crank, but not start - like if you run into a store and and come right out. Eventually it will start. Do I need the crankshaft sensor? Or what causes this problem of cranking but not starting?

My engine idles and runs fine but has codes po171 and po174


Your still lean on both banks

Either the oxygen sensors failed or slowed
down & set a code or you have vacuum leaks

When ever you remove an intake-- you smoke it before
& after the job-- to avoid vacuum issues

Fuel Trim may give you some idea where to start

Can be rich both banks & driven lean

Check the engine for vacuum leaks in the small rubber hosing around the inlet manifold, run the engine and spray wd40 around the hoses if the engine revs rise you've a vac leak. Could also be a faulty MAF sensor which is located near the airbox with an electrical connector running to it. That fault code means your ECU thnks the engine is running lean so is compensating by adding fuel. Either you're gettng extra air into the intake that shouldn't be there or the MAF sensor is sending the wrong signals.

P 0171 (m)


PO171 refers to "system too lean - bank #1", This means that the upstream oxygen sensor detected too much oxygen in the exhaust. Cleaning out the MAF (mass air flow) housing and sensor will help eliminate the PO171 code. It's also necessary to clean the upper portion of the engine and fuel injectors, to make sure they are not clogged or "fouled." check for vacuum leaks and around intake manifold. spray around manifold with engine running, if it flares up you have a leak. in most cases. cleaning the MAF sensor does the trick !

How to fix engine showing code po171?


engine running lean--check engine for vacuum leaks. Look for cracked or unhooked hoses. Also test intake manifold gasket. I spray ether on the gasket with engine running. If the engine speeds up, there is a leak. Let us know f you have more questions.

2002 Chevy Van with a 3400 code po171 too lean how to fix


Code PO171- Lean mix of Bank 1.
Code PO174- Lean mix of Bank 2.

Most of the time a P0171 and P0174 is caused by either a vacuum leak--more than likely the PCV hose and valve or a dirty or defective Mass Airflow (MAF)sensor. Low fuel pressure can also cause this condition. The PCV hose is located on bank one but can affect both sides because the other end is located on the back of the upper intake manifold. Usually they deteriorate and get a hole in it.

Clean the the MAF sensor with MAF cleaner, which you can pick up at any Auto parts store and also pick up a bottle of fuel injector cleaner. Good luck and hope this helps.
