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.

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

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.

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.

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, 03:46 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.

I've had problems w/ acceleration and throttle response from time to time, but it was due to filling the tank w/ gas the car wasn't "happy" with. Once she got a tank full of the good stuff, throttle response and acceleration went back to normal, which is quite speedy and lively. Trouble is, gas stations are like a box of chocolates...

I may be way off base, but, try a different brand of gas and see it helps. I've had great results w/ Sunoco 93. I just wish there were more Sunocos in my neck of the woods.

I admit, puny was an overstatement.

I just find the car's behavior below 4,000 RPM to be quite interesting. It has the power to GO, and does initially, but something happens and it stops... then a few seconds later it GOES. I wonder if a tune would take care of it.

roptics · 07-07-2010, 08:42 PM

Same issue here but it didn't start until around 5k (first oil change at 3700m). It used to be intermittent with the worst area 3 - 4k. Sometimes it is low power but progressive with a kick and other times it is just a complete dog unless I completely step on the throttle and get it to at least 6k or something. With the AC on the just seems like no power at any RPM. The high heat in the NE right now has definitely made it worse. I stay with Shell first and Exxon as my second choice. I'll try the battery disconnect tomorrow.

I read somewhere the Camaro SS owners have the same issue with the throttle delay up to 3k RPM. Here's a thread:
