OK guys, i just need some help getting pointed in the right direction here.

My camaro in the past 2 months has developed a bit of a quirk if you will. When i start the car in the morning it runs great, but after about maybe 10 min of driving, whenever i start to apply the brakes the oil pressure drops. It doesnt drop all the way down to 0. But on my gauge it drops down to teh 1/4 mark and sputters there. I know it is not a gauge misread because i can feel the pulsate in the engine as well when it drops.

I did have a leak a while back and it came from the oil pressure switch. But that was replaced and i have plenty of oil with no leaks right now and i do not smell anything burning while it is running.

Where else should i look?

 

what year and motor? sounds like it could be a ground issue. clean and check the ground under the kick panel on each side. sorta by the door hinges

 

its a 95 3.4l engine. Is the ground something i have to get to from the engine bay or from underneath the car?

 

check these two g200 and g201

 

I have the same problem on my 3.8. Camaro. But I also have a whinning noise
