why are my 2 cylinders not on when it cold starts? its ok when its warm but when its cold only 2 cylinders come on until it warms up then all 4 cylinders are on??? i want all 4 on like other civics

 

Do cylinder leak down tests when the engine is cold.

 

oh ok...so instead of it warm ill do it when its cold?

 

ive done a compression test and it was 179-181 all the way

 

how do u know only 2 r working?

 

Oh, my mistake, I thought you meant compression was low.

Check the plugs, wires, cap, and rotor.

 

it runs really bad when first start..we took out the spark plug wire and put it to the bolt of the head and it doesnt spark until it gets warm...

i forgot which 2 wires it was but it dont spark...and after the engine is warm it then sparks when we try it again....

my friend has the same civic but his is a coupe and mine is a hatch...same engine...but all four are working on his but on mine only 2 are working until it warms up then they all work and its fine but im just wondering why all 4 of mine arent on at the same time??

 

I would try his distrubuter and if that dont work try his ecu too
