Had this car 3 years and I've since replaced UIM & LIM gaskets, valve cover gaskets, water pump, ps pump, rack & pinion, coolant elbows and couple other things. It's currently not throwing any codes but from take off it's like I have no power at all until I get to about 40 mph. Takes maybe 10 seconds to get that fast. I'm sick of messing w thid car but at this point would be stupid to give up on it. Please point me in right direction...
