slight missfire .

[welsh.Z.S.]

​was cleaning the bay the other day with a spray bottle , something as obviously got wet as when i 1st started it it idle'd very bad , also let off a few pops then cleared itself , ran fine the next day aswell , then it developed a slight flat spot at around 1500k , took the coilpack off to see if any water etc came out and made it slightly better but could just be luck , only does it sometimes now , maybe once a day if that . any ideas what it could be before i start spending money ?

I cleaned my engine bay before , and i had a huge missfire though. How i fixed this was i took the top inlet off and pulled the ht leads out and there will be moisture on them wipe them dry, and also check the plugs as water can get into them aswell.

Took the leads and plugs out earlier and all were fine , clean and dry, got a coilpack coming this week, anything else it could be apart from the coilpack ?

​changed the coilpack and its still exactly the same , when 1st started it doesnt do it at all , after 2-3 mins of driving it starts missing , but above 2-3k its fine .. any other suggestions ?

​sorted found a slight tear in 1 of the leads which was causing it to spark which was causing the missfire , all fixed now , thanks for your help guys
