i have ulta lite auto meter guages in my car. the oil pressure guage is going crazy. when driving around it normal like 40- 50 psi. when i come to a stop it goes down to 0 some times then sneeks to 15 psi. then when i take off it some times goes back to zero. however when i start my car it goes to 50 psi after a couple of secs. so i dunno whats going on with this guage. all help is appreciate. i am over due and will be going in for an oil change in the morning.

Thanx
Brian

 

I hope for you sake I am right and it is a bad sender. Take the wire off and ground it and see if it goes to max. If so, try changing the sensor and it should be ok. I had a sender reading proper pressure in a Benz and it would drop to 0 at idle. On a FORD truck, it read 0 at cold startup for 3 mins but there was pressure. Both times you would have heard clattering if it was really at 0 psi. Hope that is your case otherwise, you might need a new motor.

 

well i went for an oil change and they were like looked like only 3 qts came out. so i guess being low my sender was actin crazy cuz the oil that was in there wasnt enough i guess

 

If you were 2 quarts short then your oil pump was probably sucking air from time to time when the oil didn't make it back to the pan fast enough. NOT a good thing. You really should check your oil once in a while.

 

Yes check your oil... I went a week without checking my oil and it was chirstmas holidays so I was baggen her pretty hard... checked it and THE DIPSTICK WAS DRY!! I am waiting to get the 400 together so i can see what kinda damage the 305 has to it

 

dry dipstick= two quarts low. In my old hyundai I did this. Dipstick was dry and it took 3 quarts to get it back to normal...the car only held 4 quarts LOL
