Subaru - Loyale :: 1991 - Bad Gas Mileage In The Cold
My 91 Subaru Loyale is killing me!
When it gets cold, and it is cold in Colorado 9 months a year, my gas mileage drops from 30mpg to 22mpg. It is costing me hundreds of dollars a year!
It is NOT my a/c - yes, I get 22mpg when I run the a/c - but the a/c is disconnected to take it out of the equation. I also lose no power in the cold.
My o2 (Oxygen) sensor is disconnected. It is bad (Engine light is on) but it is fused into the exhaust and I can't extract it.
One mechanic said without an o2 sensor my computer is not able to determine how much gas to squirt in the injectors. So why would it squirt 25% more in the cold?
This same mechanic suggested cutting a new hole in the exhaust and putting a new o2 sensor in.

I have a 1991 celica that I can not get to start. The car has the 3sfe 2.0 in it that I think came out of an 89 celica. We have put a new starter on this car, alternator, plugs, wires and distributor cap, battery and more onto this car. The car however will push start. When you turn the key everything comes on and it clicks. Nothing else happens.

I have a 1991 Toyota Celica ST184 5SFE that has only just started to have a few issues with the Speedometer.
Issue: When driving the Speedometer may jump up and down and when taking foot off the gas it will instantly drop. Happens now and then it may work again.
I have taken the car to the mechanics and they have confirmed that the car uses a Sensor for the Speedometer.
I took my car to an Auto Electrical Mechanic and he did a few tests on the car using a tool that showed the speed of the Sensor when Driving and he has confirmed that the Sensor is working correctly as he can see the speed while driving.
He mentioned that there is likely to be an issue within the Dash and possibly a loose cable or a bad resistor.
How to troubleshoot this on the Dash and how to remove it correctly without damaging anything.

My cooling fan just stoped working the other day (not sure why) i replaced the fuses and relays they are all good. Now when i unhook it from the radiator fan switch it turns on but plug it back in and well it shuts off, i put a new switch to see if it will work but it started running real rough and hard to start so i put the old one back on and nothing changed. I read the book and checked everything but still nothing and why my engine light came on and it started running rough.
its a 91 celica 1.6 (4AFE)
Toyota - Celica :: 1991 - Will A Valve Job Increase MPG
I have a 1991 Toyota Celica GT with 220,000 on it. Will a valve job improve gas milage? I currently get about 22 mpg city driving if I use medium grade gas. The reason I ask is that I was thinking of getting a new car - but a valve job would be a lot less$$$ and I just can't see buying a new car that get less gas milage.

View 1 RepliesCelica :: 1991 - Motor On Cold Or Hot Start Up Shakes Really Bad
Its a 1991 Toyota celica with the 1.6 and 5 speed trans. the motor on cold or hot start up shakes really bad and has a lot of valve chatter. Along with that, the motor does not want to rev at all, almost like you are not even touching the gas, but you have it to the floor. A little back ground on the car is, the car sat for 6 months and i bought it from a friend to drive back and forth to work to keep miles of my supra. He said that the CAT was plugged so i replaced it. I have replaced the coil pack, distro cap, spark plug wires, spark plugs, rotor button, catalytic converter, air intake, and all the air tubes that looked like they were cracking. Now I can start the car, and it does the same thing. I thought it may be out of time, just because that is sort of what its acting like. I have had the motor rev up 3 times since i have had the car. But everytime I do it back fires and DIES, the car will not start til after the car cools down.

View 3 RepliesCelica :: 1991 - Surging At Constant Speed In The Range Of 10 - 50 Mph Or So
I have a 1991 celica gt 5sfe hatchback. I am getting a surging at constant speed, at idle it's fine as well as acceleration. It only does it when trying to maintain a constant speed in the range of 10-50 mph or so. It's feels like I'm pushing the gas and letting off repeatedly. I took it to get an emissions test and it failed on the low side test with high co2 reading, everything else is fine and one place couldn't do the test because the surging kept kicking the computer out since they have to keep it at a constant 15 mph speed. I think whatever is causing the surging is causing me to fail the low side emissions. Could it be the iecu?
View 10 RepliesCelica :: 1991 - Front Passenger Brake Locking Up?
This is on a '91 Celica GT, 5SFE engine, with front disks and rear drums, and no ABS.
Whenever braking, the front passenger wheel seems to be doing much more of the braking work. In the wet, its very easy to lock up the front pass wheel under pretty mild braking. In the dry the same wheel is always the first to lock up, considerably before the drivers front, and much before they should, based on the deceleration.
I recently had to replace all the brake hoses, and a long run of hard brake line from the engine compartment back to the gas tank. I've bled the system multiple times and doublechecked all the connections, and cannot find any leaks. With no brakes applied, all wheels spin freely.
It seems like the braking circuit for the driver front wheel is not working as well as it should be. Is the passenger rear brake on the same circuit as the driver front? This seems like air still in the lines somewhere.
Could the master cylinder be causing distribution problems between the two circuits?

View 8 RepliesCelica :: 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.
