checkthe oil cooling unit ..had this problem and unexperienced ppl told me head gasket blow ..but there are 2 oil cooling units that has water passin through it one for the engine and the other for the transmission. these are made of aluminium ..over time they become porous and oil gets into the water cooling system. does ur car work like normal ..temp normal ..everything seems fine as far as guages tell u? them this is what u should look into .... jus my experience tho ..urs cud be different

danOntheRun thanks, everything was working real good for couple months well, recently the car over heated so I replaced the head gasket, there was no impression on old head gasket of being blown..Car jus overheated....
Now my next problem is the car stiffling alot before pulling off, starting real good but from the time you mash the Gas it don't want to go...couple seconds after it will go..this is depressing..any recommendation..

All the time, or only when cold?
Does it happen only in a certain RPM range?
Can you put the engine in a higher gear, (to put it under load), and the same happens when warm?

You sure right Sigmatech, it was the oil cooler, had it changed out on Saturday, flush radiator, car is working good now..I had the head gasget replaced twice and both Mechanics were a big failure and rip off..Hackim (Laromain)The last one said it will take an entire day to change the oil cooler talking bout radiator and bumper have to come out, my cuzin did in 30 mins,snap on fittings.... flushing took awhile. Tranny working fine, didn't show no discolouration in the oil from the cooler..
Thanks though..this is information that should be shared on tuner, even simple things like bleeding the Radiator....
