Celica :: 1991 4A-FE Oil Pressure Warning Light Flicker Occasionally

1991 Celica ST 4A-FE automatic, 238,000 miles, son's car, has been running great, until he says his oil light occasionally flickers on him. Car is in Wisconsin, driven maybe 2 miles one way to work every day, hasn't been on the highway is a couple months. Has synthetic 5W-30 oil with about 2,000 miles since last change.

Brought the car into the garage. Sure enough, after engine warmed up and idle got below 1,000 RPM, oil pressure warning lamp would come on. Engine sounded normal at idle and fast idle. Tough to put a mechanical pressure gauge on this engine (after to remove the alternator and A/C compressor and bracket, per the service manual, to access the oil pressure switch). I drove it on the highway, put about 40 miles on it, ran great, until I exited the highway. Anything below 1200 RPM, oil pressure warning light would come on.

Came home, removed the oil filter with intent to change it (to make sure it wasn't plugged). Smelled of gas. Oh-Oh. Drained the oil (oil level was at full mark, unusual for this vehicle, normally would be 1/2-quart low after 2,000 miles - 2 months of winter driving). Oil came out with consistency of water. Smelled of gas, and could see water droplets as I switch the drained oil from a collection pan into a jug. Thought was many short trips caused oil to never get hot enough to burn off unburned fuel blow-up or accumulated moisture, so oil was diluted, much too low viscosity.

Changed oil & filter with synthetic 5W-30 & Purolator PureOne oil filter. Took it back on the highway for 40 miles again. Highway drive was fine. Upon exiting, oil pressure warning light came on at 1,600 RPM or below. Oh-Oh. Had another 40 miles on the highway to get home. Highway drive was good again. Upon existing, oil pressure warning light came on again at 1,800 RPM or lower. Oh-Oh.

Worrying that the oil pump for pressure by-pass valve or of bearing spin-out or extreme wear (although engine sounded fine all the time), decided to order an OEM oil pressure switch. Had to take some of the bolt-ons off to access the oil pressure switch, but not all the service manual said had to come off. Took the old oil pressure switch out - looked just fine. Installed the new one, put everything back together. Checked to make sure the oil pressure warning light still came on with key in the ON position (it did), so I knew the wiring connections were good. Startup was fine (cold engine). Took it on the highway for 40 miles, after exiting highway, no more oil pressure warning light. Even tested the situation with the automatic in drive, brake applied, lights on high-beam, heater fan on high, rear window defroster on (got the engine down to 600 RPM), still not oil pressure warning light. Turned engine off, then turned ignition key to ON, oil pressure warning light comes on like it should.

Chevrolet :: Oil Light Start To Flicker After About 10 Minutes Of Drive

I have a 1987 Chevrolet Celebrity that on the exterior is in pretty rough shape but seems to run great overall. The car is only driven to and from work which is only about 4 miles each direction. So it is drive 8-10 miles a day 5 days a week. It starts great and doesn't seem to have any problems except for the flickering oil light. After about 10 minutes of driving the oil light will start to flicker whenever the car is stopped (i.e., a stop light or drive-through) As soon as I start to drive again it will stop flickering. This problem seems exacerbated on especially not days and it happens earlier than normal. It does have an oil leak so I check the oil often but this happens even when the oil is at a normal level. I don't really want to take the car in because it isn't worth anything and I don't really want to invest money into it. What might cause a flickering oil light?

Celica :: 97 GT 2.4 - Hard Or No Start After Driving Around For 20 Minutes

My 97 Celica GT runs fine , battery is solid, no fuel delivery issues, timing is good, no backfires, new air filter, but when I have been driving around for like 20 mins and park for 15-20 or so I have trouble starting up, I have to keep trying and eventually it will kick in, but last night when I got home I tested it by letting it sit for about 20 mins and tried to start no dice, tried few times, then after cooling off over night, it started right up today with no problem. I remember a mechanic that was working on it said it could be a IC chip that could be overheating, I'm also concerned that it could be an engine or ignition component that is overheating and once it cools it's easy to start.

Santa FE SM (2001-06) :: Idle Really Low / Almost Stalling And Oil Pressure Light Flicker When Warmed Up

I bought the car 3 years ago 2003 2.4L Hyundai Santa fe , I have driven it around 200 miles ( to and from shops ), I am having an issue now where once the car is warmed up ( post 15 mins ) It will idle really low * almost stalling * and oil pressure light will flicker, If I hold the brake and get it to almost 800 - 1k RPM it goes off and driving is not an issue *no knock*. I just got it driving for the 1st time in the past year, and drove it for about 45 mins in stop an go traffic, Temp light was all the way to cold, once stopped in stop and go traffic it would go up half way, as soon as I could get above 50mph it would slowly work itself all the way to the bottom?

Accent LC (2000-05) :: Oil Pressure Light Occasionally Flicker At Idle / Car Will Not Rev Past 5k

I picked up an 02' accent, 1.5l that i've been intending to use as a commuter car. Drove fairly well on the way back home, but it seems it's got some low oil pressure issues once it's good an hot. As the oil pressure light will occasionally flicker at idle, mind you the car is near dying too.

Or so I thought, it was also misfiring/stumbling fairly badly,

Pulled all connections, cleaned, dielectric grease on them, fixed some of it. And it turns out the fellow who did the timing belt last didn't exactly remember to put the bolts back on the fuel rail.... Okay, that's fixed now.

Put in a little heavier oil, and no more issues with the light coming on, but I do have some lifter noise it seems like.

As well, the car will not rev past 5k in neutral or under load. Air filter is new, and no obstructions through to the intake manifold.

I'd guess based on the missing bolts here and there, the guy was a bit of a hackjob mechanic and i'm guessing has the belt out a tooth or so.... I can't see anywhere to stick a timing light on to verify ignition timing, how to check the timing belt is straight up? It's a bit of a dog compared to the other accent i've been in. The power band is like 2000-3500 and it just won't climb anywhere past that.

Camry :: 2004 - High Pitched Whining Noise At Idle / Battery Light Flicker On And Off

Yesterday as soon as I started my car, I noticed a high pitched whining noise. As I drove, it seemed to stop, but as I slowed down and idled, it came back. After driving a couple miles, the battery light came on, so I turned off the AC, radio, and lights and it went off again, but as I sat at stop lights it would flicker on and off again.

Ford 7.3L Power Stroke (1999-2003) :: Battery Light Flicker In Time With The Idle Of Truck

I bought a 7.3 f250 with 300k mi. It had a battery light on but didn't show any signs of trouble. Eventually started dropping volts a few days later and I replaced the alternator. The light is still on and flickers in time with the idle of the truck and sometimes goes out when I'm on the gas pedal. Some nights when the lights are on the voltage drops ever so slowly until its drained. Why the new alternator didn't fix the problem? NAPA's scanner says the truck has 12.4V at idle and 12.1V at idle with the lights on. Batteries are relatively new and test fine, dual Interstate Mega-tron Plus batteries-top of the line.

Celica :: 1992 GT - Oil Pressure Indicator Started To Flicker On And Off

So I just replaced the timing belt, water pump, power steering pressure line and all associated seals and gaskets including the oil pan gasket and valve cover gasket. I fired the car up and everything appeared to be fine so I decided the next step was a nice little drive just to make sure all was well.

Everything checked out until I was a couple hundred feet from my driveway when I stopped to talk to a neighbor the oil pressure light started to flicker on and off, occasionally it stayed on for a second or two. when I accelerate the light goes away. I have not put a pressure gauge on it yet.

For example lets just say the pressure is good??? then what??? and the oil pressure switch is brand new. the oil pump passed the inspection listed in the manual and the only thing I did that it didn't tell me to was assemble the oil pump with some assembly lube after changing the shaft seal and housing gasket.

I own a 2004 Hyundai Santa fe with 40k miles on it. I drove it to Vegas about 2 hours ago and noticed that about every 6 minutes the headlight would kind of flicker. It was pretty constant the whole trip. There are no other lights that flicker, it's only the headlights. Is this a known problem?

What do I do next, I need this fixed because I have to get my Lexus inspected.

Celica :: Light Throttle Shudder And Rough Idle

I have a 1991 Celica GT. 175K miles. The car recently developed an issue where it jerks back and forth at light throttle, sort of like a newbie trying to learn to drive a stick. It happens at pretty much any speed, but is less pronounced at the higher speeds (45 MPH). In addition, it will not idle at a constant speed and cycles between 1100 rpm and about 300... or kill.

I've taken the throttle body off and IAC valve off and cleaned them both but it didn't change the behavior. If I pinch the line to the MAP sensor, the idle straightens out at about 1100 rpm. Disconnecting the MAP sensor gives good idle, but no performance while driving, so not a solution.

Things I haven't done yet: check continuity on throttle position sensor, checked MAP sensor (how?).

Celica :: 1989 Celica GT - When Pressing On Gas / Idle Drops And Then Car Dies

My brother was the original owner then passed it on to me. I then passed it on to my younger cousin about two years ago. The car is completely stock and has never been modified. Everything is OEM.Just a couple of weeks ago I was called by my cousin saying the car broke down on her .The problem is that we took it to a few mechanic shops but they still haven't fixed it ...

Problem with car: When pressing on the gas, the idle drops and then the car dies (a scary event that happened to us and on a main road). I do not wish to bring it to another fail mechanic shop.What the shops did: changed all fluids, distributor cap and plugs, new spark plugs, and replaced air intake piping with oem piping.
