I have my 2003 Discover checked today at autozone for the check engine lights. It was coming back that one O2 was bad, another was not registering (I think I may be able to figure those out) and also saying that the #2 cylinder is mis firing....what do I do about that misfire? How can I correct that?

Thanks,
Steve

 

mileage?

 

103k overall, but the engine has 40k on it...the engine was installed (from what I understand) when the car had 83k

 

what was the 4 digit code?

 

I lost the paper, I'll get back to you with that.... Thanks!!!

 

Change all of your O2 sensors, it is time. Get some 8MM plug wires (I use Magnacor) and new plugs. Either stock Champions or Bosch +4 for a little more low end torque.

 

Ok, so here are my codes:

p1590
p0134
p0154
p0135
p0155
p0141
p0161
p0140

I went to Advanced Auto to read these....Also, my brakes were a mess (front right lost the inside break bad and was using the caliper piston to stop - GF's ex husbands fault) I also replace the hub as the bearing was a mess - my 3 amigo's lights are still on, do I have to go have those cleared? I know I can clear the check engine light by pulling the battery for a bit.

Thanks,
Steve

 

This truck has been neglected big time.
So, as already mentioned, 4 new 02's, full tune up with 8 mm Magnacor or STI wires and get the ABS codes read and cleared, if they will clear, you may still have some problems there.

 

im with mike, do the o2's some 8mm magnecors and some bosch +4 plat plugs.. then clear and see what codes come back. dont just clear the codes, fix whats wrong. the abs codes hopefully you can get read at an indie shop or rent an amigo from someone on the forum.

 

It was definetly neglected...it was parked in the woods for over a year beacause it had a busted air spring and power steering pump went.

Plugs and wires were done when the engine was put in about 20k ago, BUT not sure why there is a misfire on #2....any thoughts on that?

I DEFINETLY plan to replace the o2 sensors...is there a way to find which ones are bad so I can do those first...since I jsut put 2500 into it.....
