Hey guys, this is the follow up with the solution to my previous thread:
Even though some had to have their ECM's replaced, I didn't.........
here's the follow up from the dealer regarding the P0507 code Idle speed high RPM. They have three procedures to follow:
1. Check PCV hose connection.
2. Check Intake air leak.
3. Replace ECM. ( BTW ECM is warrantied under power train for 70,000miles).
They gave me a huge run around over my Injen Intake, I ended up putting the stock intake back on so they could complete their tests. PITA
They did not replace the ECM, they did a complete reprogram of the ECM ( as they said) and that cleared the trouble.
When I brought it in the first time they wanted to charge me 1 hour labour to tell me the code was P0507 and to bring it back with the stock intake. Needless to say I was pissed , I said I should charge you guys 1 hour labour for giving you guys the code and installing the stock intake as I could gaurantee the trouble wasn't the intake! I happen to play hockey with the Western Canadian field Manager for Nissan so I flashed his card and they they would be hearing from him ( bluffing), the service guy said oh okay we'll wave the labour charge. Anyway after the second visit and the fix a couple of hours were spent they charged me an hour labour for that and I figured that wasn't bad seeing as though the code was gone and the idle was finally back to 600rpm.
On a side note there's a lot of talk regarding intakes and loss of bottom end power, this is just IMO but I will be putting my Injen back on as I noticed minimal loss in bottom end power compared to how I have it now with the stock system but a definite decrease in top end performance with the stock sytem compared. With the Injen at 4,000RPm the thing just takes off. I know there's nothing on paper or documented/dyno'd etc here this is purely by "the seat of my pants feel" and just my opinion, but my personal preference is to have the Injen on! My car came with the Injen, would I buy a new Injen for the gains?...... No, but I would buy a used one under $150. And the sound the Injen makes under WOT!!!! Almost worth it for the sound alone! Please don't start beating me up over this Intake thing, frankly I don't even read the intake threads anymore, it's a debate that will never be settled I just thought I'd throw in my two cents as I've sampled both back to back under the same weather conditions etc and it's is just my 2 cents which is probably only worth that much!! ( that's a Canadian 2 cents which is worth less!!!!)LOL. I hope the P0507 code trouble helps someone else, basically it doesn't have to be an expensive fix and the ECM is under Powertrain warranty.
