Alright, this morning there was a commercial thing for Elk Performance that I was told to go to and I did. The car was fine before this. Then I go to do a donut and I do about 30 seconds worth at about 7K RPMs. Anyway, so I park and then leave it for about two hours. Anyway, I start it up again and it wouldn't start. I have it all the way cranked and it is going up to about 400 RPMs, but no further, I tried flooring the gas but that did nothing. After my hand still cranking it and it being at 400, it sputters to a start. Anyway, so I drive back with no problems for about 10 miles. I park it, then leave it for about 1/2 hour. I come back and drive it, and from here, the oil pressure bounces from 0in/lb2 to 15in/lb2... pretty much that is the way it is for the rest of my trip home (45 minutes)... it would drive fine and the coolant level was even, but my oil pressure would always bounce between 0-15... please help me! Thanks soooo much!

 

Oil pressure sender went out methinks.

 

how do you fix that? i tried searching but all it says is fix the oil pressure sender... never how you fix it

 

maybe you just slightly flooded it the first time?

 

nope... also i just remembered... after i left the shop and stopped at a stop sign, my engine stalled out... so how do you fix it?

 

You have two options with the oil pressure sender:

1. Remove and clean it (use carb cleaner or something similar). Make sure the connectors are cleaned off as best as you can.

2. Replace it.

If option #1 doesn't help, you only have option #2.

 

so that is probably the issue? i mean that would explain the engine dieing?

 

Does your car currently start and drive fine other than the oil pressure reading funny?

 

yes... it only stalled once which i can guarantee is not my fault

 

If it only stalled once, don't worry about it until it happens again or becomes a reoccurring event.

Check the oil pressure sender and see if that takes care of your gauge readings. If you have/want to replace it, I believe they are around $100 from Mazda but I can't remember exactly.

 

i have no idea how to fix it. also, isn't it ture that if i get a new gauge it comes with a new sender?

 

oh, and if i can use an oil pressure gauge (like a handheld one) should i check it and verify it?

 

Louis, your oil pressure would not actually be fluctuating like that. It's impossible. If it would make you feel better, check the physical pressure, but it won't be fluctuating like you described. Take a sigh of relief.

 

whew... the second after i saw the pressure dropped, i would make babies cry the amount of swearing i was doing... i thought it was a blown engine

 

Check your MaP sensor hose that same thing happened to me...mine just blew off somehow..

 

nope

 

whats the part number?

 

If you're talking about the OEM pressure gauge, I wouldn't worry about it. The pressure sensor is what you should be looking at. It's a common complaint.

FYI, the pressure sensor will not affect how the car runs. All it does is give a signal for the gauge. It doesn't even connect to the ECU.

 

i bet its a plecebo (sp?) effect... when my gauges go nuts, i think more things are wrong

 

When I saw champagne bubbles in my coolant I thought my motor was gone. I went through the same set of feelings.
