Spark plg wires. belive it or not. When the truck shifts into overdive (50-60 mph) Engine rpm's drop down increasing load on ignition system. spark plug wires become impotant in this range if they are leaking you will get all kinds of strage behavior "lundging" is the most common. Good luck. Justin 9/24/2005: question on F-150 engine. Justin gave a very good answer! Also, check the plugs for cracks in any of their insulators. You didn't id as a straight 6 or a V8 and what year. Check the distributor for counter weights and make sure that this mechanism moves freely and smothly by rotating the rotor shaft both clockwise and counter-clockwise. Ford and Courier products both have problems with the weights becoming very rusted in certain humidity conditions. I've had both since 1954 and 1977. Some 3-in-one oil will do the job. Another thing I've run in to is that the arm to the distributor plate will rub against the wire that goes to the coil or the ground wire for the rotating plate itself. Either action will eventually cut through the insulation and even the wire iteself if allowed to continue. This will become a very dangerous condition, especially when making a left turn across traffic!!! Mort
It"s located on the rear manifold, between the firewall and the engine for the upper oxygen sensor(b1s1), and between the catalyst converter and the resonator for the second oxygen sensor (b1s2), between the pipe and the floor.
same thing
bank #1 sensor #2 is the oxygen sensor that is past the catalytic convertor(some mechanics call it the downstream sensor)the sensor is located between the convertor and muffler you can use a 7/8 wrench or a oxygen sensor socket if you have one
There are two oxygen sensor for Mitsubishi Outlander. Front Oxygen Sensor and Rear Oxygen Sensor
oxygen sensor is found either in exhaust manifold or in actual exhaust pipe between manifold and muffler
If the vehicle was built with an oxygen sensor, you will need an oxygen sensor.
It's integrated into the oxygen sensor. Buy a new oxygen sensor and you get a free oxygen sensor heater.
The oxygen sensor, if defective, will give inaccurate readings to the engine management computer and may lead to a rough idle.
The exhaust system has two banks. Each bank has two oxygen sensors. Bank one is on the driver's side. Oxygen sensor 1 is between the exhaust manifold and the catalytic converter. Oxygen sensor 2 is behind the converter.
Remove the vacuum hose from the oxygen sensor. Remove the oxygen sensor retaining screws. Reverse the process to install the new oxygen sensor.
Remove the oxygen sensor vacuum to. Remove the oxygen sensor screws. Reverse the process to install the new oxygen sensor.
Oxygen sensors are located on the exhaust pipe, generally between the exhaust manifold and the catalytic converter.
