Had error code PO302 when engine starts up in the morning, had this 3 times now, warning light been turd off each time haven't replaced no parts yet, been to vauxhall garage, they say possible exhaust valve cocked up, only done 33000 miles, car is 2005, they have put some additive in the petrol and now I have to see if it fixes it, 2days later started in the morning and light on again drove it shudders I stooped restarted and it goes ok what can it be ?
Code p 0302 refers to no 2 cylinder misfiring====causes injector , injector control --wiring-- low fuel pressure ---HT lead , coil, distributor cap , HT leads ---ECM
At this point you could put a quality injector cleaner in the tank or take it to an accredited service center and have no 2 injector fixed

This sounds like a fuel pump check valve problem, if the fuel is not kept in the filter and lines by the check valve it drains back into the fuel tank and causes the kind of problems you are having, you can check this by hooking up a fuel pressure guage at the test port on the fuel manifold that supplies fuel to the injectors, run the engine and shut it down, note the fuel pressure at shut down (with the test guage hooked up), walk away for an hour, come back and check the pressure, it should not have dropped more than 5 PSI You can buy a universal fuel injection pressure tester for about $25.00, cheaper than having a shop run the test. If the pressure drops you found the problem, bad news is the check valve is in the pump, the pump is in the gas tank.

Not good. I would expect the garage to foot this expence as Im sure your initial bill was far from a cheep one? If a customer of mine had suffered a similar issue, I would certainly work very closely with them to rectify the problem. There is of course a slim chance a catastrophic component failure has genuinely occured, which may be completely unrelated. However it is most unlikely this time, as when your timing chain failed the valve to piston collision/impact would have caused serious potential damage to the crankshaft and big end bearings. This symptom is not overly common in most engines where timing chain/belt failure occurs. However, all engines are different and may experience different levels of damage. A replacement engine does now seem the cheepest way forward in your situation. Perhaps the garage should source one and you might pay for the fitting only? Good luck

Sound like it could be the purge valve, it is located between the cab and the box on the drivers side, it has a plug and a hose going to it. It has a small foam filter in it which must be removed, cleaned, dried and then reinstalled.
It happened to me.
I don't remember if I had to remove the neg. post off the battery for a minute or so to reset the fault code.

you have bad valve seals again and it is possible that the valve guides are bad ( to much play ) i worked for Jaguar 13 years and i have done 100's of these and very few needed guides it sound like the seals where not done correctly at the last repair.

It sounds like the pickup coil in the distributor, when it gets hot, it goes open circuit. Changing the plugs won,t help
