Not quite sure why the engine oil would cause an issue with the knock sensor. Doesn't make any sense to me.

If that were the case I think we'd have a lot more discussion on poor performance because it seems like more than 50% of board members are running something other than the Nissan Ester.

It's always the simplest of things.

Get some CRC MAF cleaner and hit your sensors. Did it today and it helped a lot. The car obviously is not very torquey down low, but it made a pretty big difference in overall responsiveness and pep in the lower RPMs (read street driving).

I'm thinking a dyno tune to optimize A/F ratios with the intakes would do wonders for the car...

Hmmm....good tip. I think I'll give that a shot. It's only $9 on amazon, plus free shipping. Do you know if Pepboys/Autozone/etc. carries it?

I bought a can at AutoZone... can't remember what I paid for it, though. I also picked up a can of PB Blaster just cause.

Nice, I'll have to stop at a PepBoys or AutoZone and check it out. BTW, PB Blaster worked wonders when removing the stock CBE. I used it this past Friday when installing the FI CBE.

I picked up a can of CRC - MAS Cleaner ($7.xx), as recommended by M4A1, at Pepboys today. I don't know if I'll get to cleaning the MAS during the week but hopefully by the weekend.

m4a1mustang · 07-06-2010, 11:32 AM

It's a quick job, just follow the instructions on the bottle. Shouldn't take you any more than 15 minutes.

nolan1016 · 07-06-2010, 11:39 AM

where are these sensors located? Sorry if its a silly question, but I'm feeling a lack of power down low since I got it as well.

Right behind the air boxes.

Be careful... DO NOT touch the sensor with anything but the cleaner. They are easily damaged and expensive to replace.

Thanks, I appreciate the info and the warning.

m4a1mustang · 07-06-2010, 12:29 PM

Big thing to keep in mind is that this car is not a torque monster to begin with, so it needs revs. Also, I had 23k on my car when I finally got around to cleaning my sensors... so for you guys with less miles (and probably cleaner sensors), don't expect anything huge!

Oh yeah -- disconnect the sensors before you spray them!

I have 2010 with from the first 20 miles on the car I have the same issue. Now with 500 miles still the same issue. You can't tell me I have Dirty MAF with 20 miles on the car. Also the car came right off the truck.

I was never telling you that. I only said it helped in my certain situation.

And of course it doesn't change the fact that the Z is a complete dog in the low end to begin with. This car has a puny V6 with pitiful low end punch.

Endgame · 07-06-2010, 02:37 PM

Puny V6? I disagree; 3.7 liter is not a puny V6. And, I would rather have my 'fun' in the mid range and top end.

This coming from a guy that had a Stang GT to S13 w/SR20DET to RX8 to 370z.

GTLAW · 07-06-2010, 02:46 PM

I fully Agree! I have owned 06 08 350z DE and HR does not have the same power has 3.7. Car just goes.
