Question about Ford Taurus

1 Answer

1998 ford taurus wagon is showing a cylinder 2 misfire and the 02 sensor code came up. Service engine light is on and it is overheating mainly when foot is on brake as in being stopped at a red light. The car had overheated prior to the heads having to be replaced and we still have not found the original source of the overheating problem. Any ideas?

Overheating could be caused by a few things, most common is the thermostat not operating, could be the water pump not working properly, the coolant not mixed at the right ratio, 50/50 mix is the best. If it has electric fans veifiy that they are working and turning on at the right temp. Now for the number 2 cylinder misfire. Try replacing the spark plug and/or plug wire. If that doesn't fix anything do a compression check on that cylinder and see if its in spec range. The other problem could be that its not getting any fuel. theres not really a procedure to check them other than start the car and put your hand on the injector, you should be able to feel it clicking open and shut. The o2 is probably fine, It is showing to much fuel in the exhuast manifold, but that is probably because of the #2 misfire hope this helps it take 3 things for an engine to run, Fuel/air mixture, compression, and an ignition source.

ENGINE MISFIRE

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.

I have a 1998 ford taurus the service engine ligth blinks in and off and the engine is missing


you have at least one cylinder mifring. DO not drive it like this or you will ruin your catalytic converter which is hundreds of dollars. A steady light is ok, but a flashing light means don't drive very far.
Go to autozone & get a feee compuer scan. Get the DTC codes and it will tell you which cylinder(s) are misfiring. It could be a plug wire or a coil most likely.

Car bogs down after getting hot, service engine light flashing, 95 ford taurus gl . I got a computer diagnostic done, said random misfires, and the 2 "O2" sensors. However, the tech told me it was the coil...


Have the following tests performed : fuel system pressure test cylinder balance test as well as a injector balance test. Preferable an ASE Certified Tech will do the testing.Depending on what he/she says wel'll take it from there. Gotta know why its misfiring before we do anything else. Cat and 02 sensor respond to engine's combustion process
exhaust product.Lets see what the testing says.
Keep me posted

2002 taurus SEL-5 engine codes to go with light and problems


Cylinders 2, 3 have coil packs change out located on back of motor. you will have to take the upper intake off to get to them. Very easy to do. #2 center plug on back of motor #3 is on drivers side of motor. Crank sensor you will have to remove tire on car passenager side next look at crank pulley on left side of block you will se two wires the heat cover running to it.
Change these first it might correct the O2 sensor problem.
