...How can you tell? Tell tale signs to look for?

I only ask as i've had trouble with hesitation ever since i've owned the car and this morning when my petrol light came on it seemed to drive fine till i got to the petrol station topped up with my usual fuel Super Unleaded and off i went - started to drive crap after this weather the fuel is the problem or something fuel related is i'.e. Fuel Injectors, Fuel Pump, Wrong Fuel who knows?


Any1 had this problem?


Cheers

 

last time i know of a fuel pump failure the car just died and didn't start, but doesn't mean to say its not that by the way.

running funny could be 100's of different things, check the maf sensor but failing that get it to a specialist for them to have a look, you can spend alot of money chasing round a problem, never find it and then find out its a lose wire or pipe.

 

Looks like thats the best idea, i've replaced Maf & 02 Sensor's & had an Oil & Filter change and the only idea have left is to try some new Spark Plugs and check leads after that i'm stumped

 

def get it to a specialist, might be something very simple and you'd never find it.
