my imported imprezza turbo is not playing with me no more. when cold in the morning its hicking and farting, but once warmed up seams ok. until now once warmed up when i put my foot down at 4 and a half revs(i think when the valves kick in) it gives a little hick. it seams when i put my foot down it dies any one with good advice out there.

 

i'd say its the plugs mine was like that when i got it and a few weeks ago the same thing and when i put in the new ones not a bother i use ngk pfr7b but when they are cold the cars a bit lumpy

 

it was only serviced a month ago and told the spark plugs have bean changed. thats if they were. do you think it could have out to do with the leads?

 

could be one of them is faulty try get a loan of a set and see if it fixs it it could be the distributor either
