ok my car is a cam only car with a vig 3200 stall, ls2 timing chain, 160 degree thermostat and a 20k btu tranny cooler. when im driving the car is fine but when im comming to a stop the car bogs a little and go to like 500 rps then back to 1000 rpms contently and sometimes just stalls. ive noticed the oil pressure gauge go far down then back to in the middle when the car starts to bog out. does anyone have any suggestions to what could be wrong? the car was tuned by a good reputable company as well.
