HEre is a new one I have properly sorted my stuttering and rough idle.
Discovered a week or so ago unplugging the MAF made the car run fine although cut out on idle.
I removed the 'hotwires' from the maf and discovered they were caked in crap. a little dribble of petrol and a cotton bud later they are looking like new. Put them back in, the car chugged for 30 seconds then smoothed out. It now runs absolutely perfect.
So there was no needs for 2 x diagnostics, coil, relays, ECU reset, Lambda sensor, HT's Plugs, dizzy, rotor arm, injector cleaned, throttle body cleaning and probably loads of other stuff I have forgot!!
Might not work for everyone but at least give it a go before replacing things.
Going to putthe car up for sale now so whoever gets it will never have any electrical probs, ive replaced more or less the whole lot!!!!!!
