Some times hard to start then tick over lumpy then clears and run well then when revs drop engine cut out will not start no faults found on diagnostic

Start with scan. Sounds like fuel filter or pressure regulator. Check vacuum and throttle body. O2 sensor,

I’m happy to assist further over the phone at https://www.6ya.com/expert/howard_977676954994c5b2

run fault codes and look for temp sensors --MAP/MAF sensor faults

You need the engine control module scanned for fault codes first of all.

adjus the timing ignition to manufacturer specification, and make a mayor TUNE-UP , use the scanner/computer for better diagnostic.

Do not waste time and money.

God bless you

try air mass meter

It sounds like the plugs are bad or not heating correctly. Running it out of petrol can mess them up like that sometimes.

The battery could be slightly weak, making the computer go on the fritz, try a fresh battery!!!! The rev counters bounce often with a weak battery.

Leave feedback good or bad.

Thanks to some advice I have fixed the problem with my Granada. The pipe work from the exhaust manifold to the inlet manifold has a short piece of plastic pipe which needed replacing. This seems to have done the trick.

I would like to thank you for running this site. Without it I would still be re-starting my car each time I stop at a red light!

SOUNDS LIKE THE FUEL INJECTORS ARE BAD WHICH UNFORTUNATELY ARE EXPENSIVE. YOU COULD POSSIBLY GET SOME USED INJECTORS FROM A JUNK YARD FOR CHEAPER.

Hi there!

A few more things to check for you.-

A vacuum leak in any of the vacuum hoses will cause the ECU to make random guesses at what's going on.

Have you replaced plugs recently - or at all? This is probably the main cause - and certainly worth a try.

Fuel filter should be replaced at recommended intervals - about 3 years.

Clean your leads and HT gear really well with a degreasant. Any losses will be more noticable at tickover than high revs.

Lastly.........wear on cam lobes or timing belt.

Hope it's cheap for you!
Please spare a moment to rate as fixya! if any of this information proves useful. Thanks (I don't get paid for this)
