my car is 4 years old and has been in and out of the casa because of the same problem which is "pumapalya" the first time i took it there, they changed the spark splug connectors and something metal in the engine, sorry i forgot what it's called. then the second time i brought it back, they changed one of the hose...but it's still pumapalya. now i had it checked recently, still for the same reason, the mechanic is charging me 11k for tension coil. i already spent 8k for the two instances i took it there and now they are charging me 11k. i'm really hoping someone can help me out from this group. i know its really expensive sa casa but i checked with other talyers, the ones i went to have no idea how to deal with my car. any help would be great.
