Ive noticed that my cars oil pressure at idle is almost at zero and the rpms have gone down, I dont know what happened if someone can give me some suggestions, heres a picture

 

Normal. You don't need to do anything.

 

if it bothers you pick up a new oil pressure sender for $100.

 

Yes this is usually the culprit.

 

Thanks guys , where can I get one from?

 

call ray crowe @ 888-533-3400 and say you are from the rx7club and he'll hook u up =). He's the parts manager at malloy mazda.

You may not need a new sender. Remove the single wire contact at the sender (driver's/left side just below oil filter pedestal...see FSM), a little sandpaper and contact cleaner, re-connect and see what you get. The signal from the sender is at it's lowest at idle. If there's no change after cleaning and your idle is over ~850, then you probably need a sender.

Thinner viscosity oils and/or thinned oil from fuel dilution between changes also makes a difference with indicated oil pressure at idle.

 

Ok so I think I mightve checked the right wire, but its raining out and I dont want to mess with any, My car usually idles at 1.1k I know its high but its what the guy at jrx did, now its idles at 700-900, and when I press the brakes it almost wants to die, the oil pressure is still low, would lucas oil be the culprit I put some in to try and stop a leak , any help would be appreciated!
