[gaz16v]

have u had a misfire for a while

 

[Guy]

did you reconnect the spark plugs back up? :clown:

 

[Djw John]

Did you check the spark plug gaps are right?

 

[mr bognor]

Yeah id say gaps to .

 

[smillie]

if its not the gaps, maybe its ure ht leads.
Perhaps before, when it was juddering, there was a short in the leads. Now they r shorting somewhere else and u r getting a tiny spark?
Perhaps the dizzy cap and rotor arm need replacing

 

[smillie]

in the dark, check to see no shorts off the leads. (sparks going from leads to the block)

ye i have been having misfires for quite abit...a month or so. i will see if there are sparks showing in the night. however last night i tried turning the engine on but it wont igniting so i opened the bonnet fiddled about with the ht leads and it worked. then today this morning i turned it on but it was stuttering and then after 3secs of stutter the engine turned on. its fukin weird. lolz.

 

[gaz16v]

sounds like ht leads but if its been mifireing for a while could of fu*ked the catalyst

 

[kundi13]
