can someone show me pics of where they are located??? 1998 disco 1

 

They very rarely go bad on a DI.
What is the problem and what have you done to try and correct it?

 

its running super rough and barely idling... stalls too... misfires while driving.. ive ordered a set of 8mm magnecor wires and gonna get new plugs too once i decide which ones will work best....

 

could it be 02 sensors or do they not do that?

 

No O2's will not cause that.

How long have you had the truck?
How many miles on it?

 

What would bad o2s do?

 

Bad O2's will cause over fueling or lean running.
O2's help control the air/fuel mixture, thats all they do, nothing more nothing less.
The ECU takes inputs from the air intake temp sensor, the MAF, the coolant temp sensor, the throttle position sensor and the O2's to determine how much fuel you need.

The crank sensor tells the ECU the engine is running and to supply power to the fuel pump as well as spark.
The knock sensors retard or advance ignition timing based on fuel quality and load on engine.
The cam sensor controls injector timing.

 

Great info Spike, I learn a lot on here with those kind of explanations. Keep up the good work.

 

Thanks for the info any idea what my problem could be?

 

Once you install the copper spark plugs and new plug wires we can go from there.

How long have you had the truck and how many miles on it?
