So I am just going to use a jumper wire with a t-pin connector and ground it to the frame or nearest grounding point. Is that correct?

I have thought of a lost ground, and am still thinking that may be the culprit of my other electrical issues as well. I have RAVE just no idea how to interpret the wiring schematics when comparing it the the vehicle itself. I am assuming it would be the same ground that the amplifier is hooked...

I did have the Power steering bracket off recently to replace it. I will definitely check that out. Thanks!

I have contemplated it. Just trying to save $200+. Anyone know of another MAF that will work other than Land Rover?

I changed the plugs and upgraded to Magnacor wires less than a month ago. As stated I am using an Ultragauge. My upstream O2 sensors are only showing voltage upon immediate start-up, and quickly go away as the truck warms up to operating temperature. On the Ultragauge I am also usually not...

My apologies I am getting codes: P0327:Knock sensor 1 circuit low input (bank 1 or single sensor) LH bank signal less than threshold determined from ECM model above 2200 rev/min P1130:Oxygen Sensor Fuel Trim at Limit *Codes* A U P1150:Oxygen Sensor Fuel Trim at Limit *Codes* B U After...

I am in need of help, before I BURN this truck to the ground, with repairs/diagnosing issues with my Land Rover Disco II. I have a knock sensor code and different O2 sensor codes that I just can NOT seem to get rid of, I have already replaced all the sensors and cleaned all connections, as well...

So all the sudden my 12volt plug stopped working, my compass in the rear view mirror stopped working and my radio turns on, but has no sound. I checked all the fuses that correlate to those components, but all are fine. Anyone else had this issue?

I should have included that, 91 octane only.

Ok ladies and gentlemen, I have an issue that I have been trying to narrow down for some time now. These three codes have been the bane of my existence for way too long. P0327: Knock sensor 1 circuit low input (bank 1 or single sensor) LH bank signal less than threshold determined from ECM...

So after much frustration and cussing at the Land Rover I finally figured out what the issue was. Had to tear the motor down to the heads and replace the $15 lower intake gasket. 8 labor hours later it is running like a champ! And saved myself $600 in the process!

So I dropped the Disco off at a local shop to get rid of the old burned out cats. When it gets out I am going to replace the lower intake manifold gasket (valley pan gasket). I'm thinking that could be causing all my random misfires and will be replacing the plugs with OEM equivalent plugs.

I found a local shop that will weld in test pipes, for off road use, for about $100 including parts. Dropping it off today.

My resonator has been missing for years now. I dont mind the grumble. I figure no matter what it will be quiter than a suburban that i had glass packs on.

So why is it you like to set the gap at .37 and everyone else says to gap at .40? Just a question not accusatory.

Well I do believe we have a winner. I am removing the cats and sticking some test pipe under there. Of course this is for "testing" pupurposes only and will only be used in "off" road applications. Thanks for all the insight everyone and all the real world info mbrummal.

No emissions down in Colorado Springs unless a dealer is selling a vehicle, and dont plan on selling the Disco. Not to say that I wouldn't, but no plans in the immediate future. If I did sell it, once I'm done with all the planned mods, it would only be to an off road enthusiast anyway. And it...

Sorry I missed your question about the plugs. I installed Bosch platinums about 4 months ago. You are not the first person to tell me that those plugs are horrible. Do you recommend original plugs? I think they were champion coppers or were they autolites? The misfire codes I will deal with...

Kyle: I have no sort of fluids ever leaking anywhere near the o2 sensor plugs. I did have valve covers leaking, but fixed that before any issues. I do not have a boroscope nor am i going to purchase one. If you or anyone on here lives close by and would like to loan me one, that would be...

You said not the rears bit what about the fronts?
