Mazda :: Oil Pressure Gauge Vacillating Wildly Between 30 And 60
Jul 2, 2013
I have a 1991 Mazda Miata. Recently I noticed the oil pressure gauge was vacillating wildly between 30 and 60, whereas it always stayed at 30 before. I checked the oil -- it was fine. I took it to my nearby mechanic who said it was the oil pressure gauge. He replaced it with a Miata part. Now the oil pressure stays at 60 once I'm over 20 mph. So what is the correct oil pressure setting and do I need to take it back to the mechanic?

2004 Ford Explorer Sport Trac - Gas gauge indicator arm swings wildly beyond normal arc of travel and lies on one side or the other of the E & F labels in a seemingly random fashion. Some days, the indicator restrains itself to travel within the usual & customary manufacturer's boundaries. Other days, it falls to one side and listlessly rests there until it flops to another position, independent of the amount of gas in the tank. Ford dealer said that this intermittent activity cannot be corrected until the gauge fails completely and forever.

'97 F150 4.6L 4wd automatic... My gauge jumps around, sometimes it works and other times it shows no pressure. Could that be the oil pump? Or is the gauge most likely bad? Whats the actual purpose of an oil sending unit?

Last week I was driving on the highway and noticed the oil pressure gauge showed no pressure. Limped a half mile to the mother-in-laws and called for a tow. As my truck was pulled onto the flatbed I could see oil all over the bottom of the engine, tranny, rear end, etc. Turned out to be a bad oil pressure sender, which was leaking enough oil to blow the plug off the top of it.
I replaced the sensor, cleaned the engine and under-carriage, checked oil level (which showed no loss of oil) and drove around for a week without an oil pressure gauge while I waited for a new pigtail. Put the pigtail in yesterday and drove it today for the first time since. Gauge was working, got to the bank and it was reading zero pressure again. Limped home and watched the gauge go back up quickly and then back down. This happened twice and was showing pressure when I shut it off. Checked under hood, no oil leaks and plug is still secure.

The tire pressure warning light has been on in my car for about a week. The dashboard computer says that the tire pressure in the front right tire is 17 psi, but when I use the pressure gauge, the reading is almost 40 psi. Is this something I should be concerned about? What could be causing this problem?

2007 Santa Fe 3.5 ... All of a sudden today the engine is vacillating and at idle shuts off. I have to keep my left foot on the brake pedal and the other on the right to keep it running without lurching forward. Does this sound like the throttle body?

1996 Mazda Protege, 125,000 miles. Temperature gauge on dashboard moves very little.
Do I need to get this checked out, ie, if not what would happen? (I have had car in recently for other problems but no one n the shop mentioned it, even though they have had the car out for a drive).

1996 Miata. The hood of my car is so hot that you could fry an egg on it. The hood is so hot that you can not put your hand on it. The heat actually comes through and can be felt on the legs of the person in the passenger seat. The temperature gauge reads normal. This began recently. I took it to the Mazda dealer who said it was normal?

My car is a 2006 Mazda Miata, stock except for being lowered and having a different muffler. Nothing really noteworthy about it. I did run over a big chunk of something a few years ago that cracked the plastic undertray under the nose of the car and dented the bottom row of the condenser, but the problem I'm having is more recent.
About a year ago the AC stopped working. I took it to one shop that found there was no refrigerant in the system. They refilled it, and a few hours later it stopped working again. I took it to another shop that detected a leak in one of the schrader valves (the low pressure I think). He replaced that, filled it, and it worked again for another few months.
Recently it stopped working again. I took it to the same guy that replaced the schrader valve and he found that the high pressure hose had failed. He replaced it and refilled the system. It worked for a few hours. Then when I was sitting at a drive thru, a massive cloud of refrigerant erupted from under the hood and the AC stopped working. Took it back to the guy and he found the high pressure hose had blown off. He put it back on, refilled it, and the same thing happened again. Sitting in traffic, the high pressure hose blew and all the refrigerant poured out.
I took it back to him again and he put the hose back on and refilled it again. We let the car idle for about 30 minutes with the AC on and it worked fine. During this he had the high pressure gauge hooked up and it read between 150 and 175 with the car idling (about 70 degrees F ambient temp). He didn't have the low side gauge hooked up. We did see that the fan is working and kicked up to the higher speed. He did say he checked the dryer and that it looked like the bag that held the desiccant was intact, but he didn't mention replacing the dryer in any of these visits.

I have a 2001 Miata. It's been over 100 degrees daily lately. The AC will blow sort of cold for about 30 minutes and the temp gauge will move towards the H hashmarks. If I turn the AC off, the gauge will slowly drop. I've also noticed that the amount of cold air is decreasing as time passes. In fact, the other day, the system was blowing air hotter than the outside temperature after about an hour drive.
The viewing glass has bubbling stuff flowing thru it. The recently flushed radiator is full as is the overflow reservoir.

Stopped in the dealer to look at a new Prius. Already have a 05 so I sold on the vehicle but was told some things have changed so I should drive it. I hit the power button and the engine proceeded to make a terrible noise like metal hitting plastic. So I shut it down we popped the hood and restarted, the engine was bucking side to side and finally quit down to a normal.
Granted it was cold (22 degrees) and I don't know when the vehicle was last run. They only have 2010 on the lot, I was looking for a II or III and a nice color (tired of silver and don't want white or black) and this was a red III, only one in the lot and the one they wanted to sell me. Not sure I want this one.

A few weeks ago, my 09 Sonata V6 starting fluctuating (slightly) abnormally when starting from a cold start. I attributed this to the cold snap (25F mornings down from 40's). To be safe I used a fuel system cleaner at the next fill up.
When the issue didn't immediately go away, I was a little concerned, but extremely busy with work. After 2 weeks of needing to start the car and let it warm up for 10 minutes... things got a lot worse.
RPMs started fluctuating between 2500 and 500. Rev, choke, rev, choke. I got it to the dealer... but it had of course warmed up. Another thread had a similar issue, so I checked for and got an ECM update, reset the adaptive memory, and had the (just due) transmission flush.
No change. The next night, I parked the car in the dealer's lot and let them start it. I suspected the Throttle Position Sensor (TPS) but wanted the dealership to independently confirm. The head mechanic definitely noticed it, confirmed with me, and replaced the TPS, did a carbon cleanout and oil change. So far, 2 weeks later, no issues.

My 02 navigator does not idle right when in park or sitting at stoplight. I've gotten codes po171 and po174. The truck ran fine for a good 3 months after the (service engine soon light) came on and I got these codes so I decided to do nothing.. Now it idles bad and has even shut off twice on me while pulling into driveway. I changed the MAF and that did nothing.. Should I assume its the o2 sensors or is there a chance my CAT is shot.

What would make the oil pressure gauge fluctuate and go to zero? I already replaced the oil sending unit, and changed the oil and filter, whats left? maybe a bad gauge?

2002 Chrysler Town and Country. My speedometer jumps wildly and then goes clockwise and rest without working. The trany hesitates and has a jerking when sitting in drive, and slow to shift into 2nd gear. We have replaced speed sensors, wiring and connectors, and now are thinking the chassis control box may be next.

So I have an 88 k1500 with the 350 that the previous owner removed and rebuilt... Didn't hook a lot of stuff back up etc... It's like a puzzle. It runs good for the most part but the oil pressure gauge in the cab pegs out when it's running. I've heard 1989 and older 350 engines have 2 oil pressure switches/sending units. I know about the one up by the distributor. But can't seem to locate the other one. Also what does the one by the distributor control? And what does the other one control?

Can I read oil pressure on my scan gauge II ? If so, how do I do it?

I've been noticing recently that my oil pressure gauge has been hanging on "0" until I drive it for awhile, then it will go up to a normal level of around 180-200. It used to register the pressure quicker. The oil level is fine. In fact, I just had my 5K (at 6K) service a month ago.Again I ask, is this normal?

I need to know how to install an oil pressure gauge...or what is the location on the oil filter flange where this thing gets installed...

I'm having an issue with my truck. It only seems to happen during warm 80+ weather. In the mornings, and during colder weather, the truck runs perfectly.
My problem is; Every time I go to get going and feather the clutch, either in 1st or reverse, my truck bucks wildly.
I changed the plug wires about 500 miles ago, and am about 4000 miles on a rebuilt engine (plugs as well) and new clutch/resurfaced flywheel. The clutch reservoir is full and I haven't noticed any leaks. There have been no codes thrown.
Could it be a possible fuel problem? I think I changed the fuel filter about 7k-10k miles ago.
I was also wondering if the Gotts mod could be causing it. I did the mod during the winter time, and this is my first summer with it on. My air filter is fine.

We have a 99 Suburban LT 5.7 V8 4x4 with 210K miles. My wife was driving the vehicle the other day and while at a stop light the oil pressure got very low approximately 20psi according to the gauge. I need to find the oil pressure sensor location to check the true pressure using a pressure gauge but I can't seem to find it. From what I've read it should be by the oil filter or by the distributor cap or on the underside of the engine. It's neither around the oil filter or the distributor (using a mirror looking everywhere) nor on the underside of the engine.
What I have found is two sensors. A sensor I believe by #1 and #3 spark plug (driver's side) screwed into the block and a sensor on the passenger side of the engine (screwed into the block) accessed from underneath the vehicle. The sensor on the driver's side of the vehicle appears to be the best candidate however neither of the sensors looks like the replacement part when I view the picture of the sensor online.
