well started my car up yesterday and it was misfiring as if it was only running on 3 pots well i took the ht leads of each plug 1 at a time and 4th plug it seemd it was not sparking properly well anyway got back in the car give it a few revs and it was fine so i thought great anyway started her up this morning it done a mad misfire then just cut out now it wont start at all i have checked the sparks from each ht lead and they are very slow on every pot any body got any ideas on wat it could be thanks

 

anybody some one must have a clue also it over fueling

 

very slow spark they traval at the speed of light
do you mean weak spark.well first things first
1 check ignition coil connections,and main coil ht lead, remove and refit them
2 check your dizzy cap and rotor arm for cracks and burn marks
3 check the crank sensor (its down by the crankshaft pulley 5 o clock position as you look at from the front)) make sure theres at least .5 to 1 mm between it and one of the 4 raised stubs on the pulley
4 check the multyplug connection remove and refit on the ignition amplifer,its behind the passenger side strut top and is bolted to an aluminium heatsink block which is secured to the inner wing
i could go on and on but see how you get on aith those for the moment
you could be lucky and it might just be a worn out coil so try swap one for a good one and see if it helps

 

ok thanks ive checked all them apart from ingnition amplifier wat i mean about weak spark is it should spark contant very fast like a dddddd but its more like a
d d d d d very slow on each output if you no wat im trying to say the cars been sat in the garage about 3 weeks scince last use i suppose

 

well it started up today after loads of misfire then i put my foot down and reved it away after a few seconds it was fine running fine drove it round the block and it was fine i think it might be spark plugs going to try them just for curisity how to you adjust the air metre near the ecu
