I have these six codes:
p0734
p0733
p0327
p0171
p0174
p0340

I am thinking a vaccum leak and new plugs / wires... I hoping that is all that it is but wanted some input. I have not noticed much of anything other than the rover "chugs" a little when I have it in 3rd around town.
BTW: Is it bad to clear the lean bank codes? Auto zone dude said that it would mess with the gas mix and cause probs but I've done it before without anything happening...
Thanks

 

The AutoZone dude is a idiot.
Their scanner will tell you what the codes mean.
The ECU does nothing with the codes but store them for data retrieval, it does not use them to run the engine.
You can borrow their scanner for $160 deposit and clear the codes yourself and then return the scanner and get your money back.
Thats what I do, use your AutoZone Rewards card and rack up some free money.
Just a tip though, do not use the money on your rewards card to pay for anything that has a core deposit, they will apply that money to the core charge and then not give it back to you when you bring your core back.

 

Thats what I thought spike! but every once in a while they are right! I just take my car there and the fellow said that I could clear them but he couldn't (due to new state laws). Anywho, does my diagnosis sound right? Is there an online list of codes specific to the land rover? (nevermind I found a list that tells all but the 733 and 734)

 

Maybe you misinterpreted what the guy said? Those codes cause a bad gas mix and clearing them will not fix it. You can check for vacuum leaks, but 4 of those codes point towards a bad MAF sensor. It looks like you have a knock sensor and camshaft sensor code too, not sure how that fits into the mix though.

 

Wow, from my list all the codes are all over the place.
If she has not had a tun up in a while I would start there.
Clear the codes and then see if they come back.

 

Why are you wanting to clear your codes when they will come right back? Do you not realize you have a bad MAF????????
You have a crank sensor code showing as well as a a Bank 1 knock sensor showing.
I would seriously advise you find a mechanic and start going at this in the correct way.

 

Thanks for all the input. I was going to clear the codes because I now know what they are and wanted to see what poped up again. Like I said I haven't noticed any changes in the rover's behavior to suggest that my MAF is going bad so instead of just throwing one on, I thought I would wait and see. The codes have been on there for a while (the ones that lean towards MAF) but again I have felt no loss of power and from what I have gathered, it would seem pretty obvious especially by now if it was the MAF but please correct me if I am wrong. BTW Mike I thought I was going about this the "correct way" as in, get the codes, clear the codes, find what is wrong and fix it. I am not trying to half-*** it.

 

Does anyone have any ideas about what is actually wrong with my rover? Other than MAF and plugs/ wires?
