Question about 1994 Toyota T100

1 Answer

OBD2 read Misfire on 2,3 and 4 cylinders

Truck is a '95 Toyota T-100 4 cylinder engine. 100,300miles on truck. Engine light came on while driving, blinks like a 100 times then stays on for a while, then starts blinking again, Truck never got hot while driving. Had read with OBD2 reader, said misfire on cylinders 2,3,&4. Changed plugs, coil, rotor and fuel filter. Those didn't help. A day later Truck won't start now. Do you think it may be the fuel pump? (The problem first started on a Friday and by Sunday the truck won't start up now). Thank you, Scott

Misfire in #2 cylinder over 1500 RPMs 2006 Scion


I would try swapping coil #2 with on of the other ones and see if the misfire changes to the other cylinder. If it does you have a bad coil. If it stays on cyl.2 check the spark plug wire or fuel injector.

OBD2 Code was misfire in cylinder 2. Replaced all plugs and wires. Misfire gone but the engine check light is still on.

Ck engine light is on and miss fire #5


There are few possibilities that can cause engine misfire issues. It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

Missing,viborating


Misfire could be a number of things:
a) spark plugs - change them if used over 15K miles - inspect/regap.
b) spark plug wires - change them if over 15K miles - inspect
c) ECM (electronic control module) - test with HEI (high energy ignition) tester.

The vibrating tells me that the engine is running on less than its normal compliment of cylinders - the shaking is produced by the imbalance caused in the engine by one (or more) cylinder(s)
not firing at all.

The "Check Engine" light probably is coming on due the the misfire condition. Go to Pep Boys or
Advance Auto Pats, where they'll tell you (free) your codes causing the "Check Engine' light to be
lit - the code coming from your truck's computer will probably be one or more of:
P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel

I would go with the ones autozone gave to you.then I would check the coil packs for those 2 cylinders and see if that's the problem. If that ain't the problem then I would check the crank sensor

Testing your OBD2

Before You Begin
Since all vehicles are not the same please refer to the manual supplied with the OBD2 code reader for vehicle specific instructions.
Is your vehicle compliant?
All cars and light trucks manufactured since late 1995 should be OBD2 compliant. Two factors will show if your vehicle is definitely OBD2 equipped:
  • There will be a note on a sticker or nameplate under the hood: "OBD2 compliant”
  • There will be an OBD2 connector as shown below
april08_img1.gif
Pin 2 - J1850 Bus
Pin 4 - Chassis Ground
Pin 5 - Signal Ground
Pin 6 - CAN High (J-2284)
Pin 7 - ISO 9141-2 K Line
Pin 10 - J1850 Bus
Pin 14 - CAN Low (J-2284)
Pin 15 - ISO 9141-2 L Line
Pin 16 - Battery Power
Where is the connector located?
The connector must be located within three feet of the driver and must not require any tools to be revealed. Look under the dash and behind ashtrays.
Important info about OBD2
  • Can diagnose/check engine problems in all CAN and OBD2 vehicles (1996 and newer) and many of the most popular OBD1 (1981 to 1995) vehicles
  • Features unique patented all-in-one screen display and LED display for quick emissions check
  • Automatic refresh updates data every 30 seconds when connected to the vehicle - an easy way to verify repair completion
  • Code definition can be displayed in English, French and Spanish
  • Can be Flash updated with a standard Windows® PC
  • Features memory/battery backup for off-car review and analysis
Connecting
Connecting the OBD2 Code Reader is as simple as locating the DLC connector. The DLC connector is usually found under the driver side (left side) of the dash. The cable attaches only one.
Reading the LCD Display
april08_img2-small.gifClick to enlarge
Before you start testing, take a good look at the LCD display. The illustration above explains what the various icons mean and how the DTC (Diagnostic Trouble Code) will be displayed. The unit is self-powered by three-AAA batteries and will let you know when they are running low. When connected/receiving power from the vehicle, the CAR Icon will display.
The OB2 code reader is a very simple tool to use. Once it is connected, turn the power on. Once the ignition is switched to the on position, the code reader is checking the system for any stored DTCs.
The meaning of each DTC can be found in the manual supplied with your code reader.

Example: the code reader displays a DTC PO309, Cylinder 9 misfire was detected.
P0298 Engine Oil Over Temperature P0300 Random/Multiple Cylinder Misfire Detected P0301 Cylinder 1 Misfire Detected P0302 Cylinder 2 Misfire Detected P0303 Cylinder 3 Misfire Detected P0304 Cylinder 4 Misfire Detected P0305 Cylinder 5 Misfire Detected P0306 Cylinder 6 Misfire Detected P0307 Cylinder 7 Misfire Detected P0308 Cylinder 8 Misfire Detected P0309 Cylinder 9 Misfire Detected P0310 Cylinder 10 Misfire Detected P0311 Cylinder 11 Misfire Detected
Once you know what the problem is, you have to determine what's causing it. In this case the intake manifold gasket was faulty. Once the repairs have been made, it is time to clear the DTC and check the system to verify the repair.
Clearing the Diagnostic Trouble Code (DTC)
Clearing the DTC is very simple. Press the ERASE button on the code reader. A message will display on the screen; "SURE" for conformation. If you wish to clear the DTC press and hold down the ERASE button again until a message appears on the screen "DONE". If you did not wish to clear the codes and hit Erase by mistake at the screen message "SURE" simply press the link button to return without erasing any DTCs.
When you clear the DTC(s) from the PCM (Power train Control Module)you also clear ALL of the other gathered information that the PCM has collected, including Freeze Frame, Drive Cycle data, manufacture specific enhanced data end everything stored in memory is erased - just like if you cleared the Cache files on your PC.
The vehicle's PCM will need to re-learn the information that was erased. Don't be alarmed!! This is easily accomplished just by driving the vehicle. All you have to do is get driving.

Good luck and check the OBD 2 connection port.
