hi guys i decided to replace the plugs (NGK) with a new set of Bosch... after i did that she runs like a bag of snot! The old plugs were well and truly worn down.
Have i made a mistake by putting the bosch in? any suggestions? |

You put the leads on the right plugs?
define 'runs like a bag of snot?'

you probably didn't put one of the leads on the end of your new plug(s) on correctly.

or the ECU needs to be reset to learn the new plug gap

ok first check that all the leads are on the plugs tight, and on the points tight.
failing that pull the plugs out and check the gaps. I once did plugs on my s**t, ran like s**t, ended up being plug 6, had no gap at all, was squashed in the box.

bag of snot= poor idle, loss of performance
checked all the plug leads on tight and correct firing order. The plugs came pregapped @1.1 mm so im at a loss..... |

Sounds stupid but dissconect and reconnect the plugs one at a time. Islotae which cylinder it is and put the old plug back in. Possible you cracked the insulation when fitting (don't be
 , we've all done it). If fitting the old plug doesn't fix, try new leads. May have cracked the insulation on those replacing the plugs.

You may have broken a lead taking one off. Remove them one at a time and isolate the one that is not firing.
