ok my problem is when my car has sat for long enough for the engine to completly cool down im having a problem with it being VERY slugging and barely moving unless i let it warm up for atleast 10 minutes and even then untill it's a normal operating temp's (about half way on the gauge) it will act very sluggish.. but once it warms up it's perfect?? what could this be? it never did this before..:aigo:
