Hi guys,

got a d16z6 civic

basically car occasionally looses power...

i can be driving and it will be all good and normal....

Then sometimes i can be driving and the car will have the power of a slug refusing to climb revs quickly at all. i also notice the engine tone alter when i give full throttle (it sounds alot deeper and louder but isnt revving higher)

then sometimes the car will jerk in between the two making me jump all the way down the road!!

i cant see any patterns or correlation between when they happen or not

i know my z6 is slow but i mean when this happens its slower than usual!

 

also just checked and i think cylinder 4 isnt firing properly is this what would cause this?

 

if u getting spark from the wire then check the plug.. when was the last time u had a tune up?

 

well ive just swapped the engine in so ive no idea!

 

"Here's your sign"

 

tune it up. cap, rotor, plugs, wires etc.

 

clutch? put it in 5 gear and floor it, does the RPM rise? if it does then the clutch is slipping.. and stuff yeah : D

 

its not the clutch as it looses power in all gears, i cant see any pattern in when this is happening as i just tested it and it was fine.. but on the way home about 1 hour ago it was jerking like crazy :S

 

sounds like a mechanic mystery, i like it. find out and post it thanks! : )
