My peouget 207 was done a cylinder head, now it starting for few minutes and cut off,it does not want to idle,it had been standing for over a month

For issues like this you need an auto electrician with a pro grade bi-directional scan tool computer to diagnose. The misfire may just be spark plug condition, but it could be a sensor issue. It is better to pay a pro and only change the parts that need it rather than 'let's try replacing this' method of repair.

indicates failed valve stem seals
when idling the vacuum in the system sucks oil past the seals down the valve stems and into the cylinder inlet ports behind the valve heads
on acceleration that small amount of oil is allowed into the cylinders indication blue smoke on take off
Blue smoke on hard acceleration is an indication of worn bearings as the bearings are pressed ******* the crank pin, enlarging the clearance on the other side which allows excess oil up onto the cylinder walls which the oil rings cannot control

AutoZone has free manuals online. Good luck.

Could be crank shaft sensor.

I will suggest that you replace the fuel filter

try higher amp battery and or a new starter

Hi, think i might can help you, have you done a fuel pressure test if not here what you need to do.

1. Start and run the engine. Verify normal fuel system pressure of 339

kPa +/- 34 kPa (49.2 psi +/- 5 psi).

2. Stop the engine. Verify that the fuel system pressure does not fall below

207 kPa (30 psi) in less than five (5) minutes.

3. If the fuel pressure does not fall below 207 kPa (30 psi) in less than five (5)

minutes, then the long crank time may not be due to the fuel system. Further

diagnosis must be made to the entire engine system.

Hope this helps you, because lack of fuel can cause a missfire and by what you said this is were i would start before spending any more money. If i can help just re post.

Thanks dodge tec

hello, try this, 1. when your car is cooled down. remove the radiator cap from the radiator. then fill the radiator to the brim. then start your engine on idle. let your engine warm up a while while watching the coolant from the brim of the radiator. try feeling the upper radiator hose, during the time you have started the engine. you should feel the upper hose heat up quite a bit. watch the coolant flow, if the coolant flows free like a stream then stops a few seconds later, your thermostat valve is doing its job. going back to the coolant flowing, you must not see any air bubbles just like soap suds flowing with the coolant. aside from this your cooling fans should kick-in after a few minutes and automatically cuts-out after a few minutes also. IF YOU SEE BUBBLES, THIS IS A SIGN THAT THE SOME OR ONE OF THE VALVES ARE NOT SEATING WELL, OR IN WORST CASES, THE ENGINE STALLED DUE TO AN OVERHEATED ENGINE; THE CYLINDER HEAD  COULD BE WARPED. that the worst thing that could happen. IF THE FANS DON'T CUT-IN AUTOMATICALLY, CHECK FOR BUSTED FUSES; IF ITS THE FUSES ARE OK, THEN THE FANS THEMSELVES SHOULD BE CHECKED IF THE FANS WORK AFTER DIRECTLY CONNECTING IT TO THE BATTERY(this should be done at a service shop), THEN CHECK THE RELAYS, AND TEMPERATURE SENDERS. 

well, these are few steps that could be done if your a do-it-yourselfer. hope some of this works for you. bye

100% sure it shows one of your cylinder compression is weak, please do a compression test to isolate the problem and get the head/pistons checked . This is a known problem with VW/Skoda 1.2 3 cylinder mills..

May I suggest to use a OBD2 scanner and see if it could be a setting in the ECU (computer) that could be out... or engine part malfunction... it will scan for any errors... sounds like it could be the airflow sensor perhaps??
