Have you tried the use of Seafoam. I found it really help in starting and idle.
Click this Seafoam link for more info

I will try the Seafoam and see if there is any improvement. If that does not help out, any other ideas?

Engine mount issues (aka clunking sounds) by pethelman

Just an update from post #483. I did order the right front engine mount from
 
http://www.infinitipartsusa.com
 
for $114.48 and installed it myself in less than an hour, using nothing but common tools:
14mm sockets
Mutiple 3/8" socket drivers
18" breaker bar
small floor jack and block of wood large enough to support under the oil pan
a couple of 3/8" wobble extensions (from Harbor Freight)
 
The old mount was sagging by over a full inch. The new mount basically restored the correct alignment of the engine on the right side. The loose clunking sound that I used to hear when going over rough roads or dips, short bumps, etc. is now completely gone. The engine noise level inside the car is considerably lower now when first starting in the morning. Definitely worth taking a look at the right front mount if you are experiencing the "clunking" sound.

Somewhere along the line somebody recommended cleaning the maf with some crc maf sensor cleaner. I purchased a can from autozone and tried it. At first it ran rough and the check engine light came on. The more I ran it, the betteq it got. Now it runs like a champ. I guess the computer had to relearn it and now the check engine light is off and it is as smooth as the day I got it. Somebody also recommended using seafoam. I bought a can as well, but I have not used it yet. I will wait awhile before I add it to the fuel. Thanks for the help. I will keep you posted on any changes.

Update. Ever since cleaning the maf sensor with the crc maf sensor cleaner, my car has never ran this good. After spending nearly 2800.00 on repairs it took a 7.00 spray cleaner to fix the problem. Unbelievable! My next tank of gas I am going to add the Seafoam additive. Thanks again.

After spending nearly 2800.00 on repairs with the parts changers, I happened upon a post about maf sensor cleaner. I decided to invest 7.00 on a can of maf sensor cleaner purchased at my local autozone. I removed the maf sensor and sprayed the sensor from both sides. I re-installed the sensor. It only took about 30 minutes to do the whole job. The car started and ran rough, the check engine light came on. After driving around for awhile it started to smooth out and run great. The check engine light went out and I tell you, the car is running like a new car. I am assuming that the computer had to relearn the maf sensor? I don't know. I do know this, it has been a little over a week and the car is running great. I hope this helps anyone with similar problems. Cheers!

Electric Motor Sound on Start Up and Stop by pokerchips69

Hi all,
Haven't posted before. Have a 2002 I35t with 83K. Black/Tan. Great car for my commute (35 miles each way) even in Chicago winters.
Recently did all 4 brakes and rotors and now am getting a whirring electric motor sound on start up and stop. Only hear it now that the weather has been nice and windows are down.
I read a post a few years old that said it may be the ABS system doing self-diagnostics. Any opinions out there? Do I need to worry?
Thanks for any and all input!

If the sound comes from the belts then either they are loosen or old. When weather is a little cold and humid, they make squeaking sound. I used a belt dressing spray bottle from an Advance Auto Parts store to spray on both belts and pulleys. They became very quiet after a couple days of driving.

HELP: Not your typical "won't start" issue... by pb13

Hoping the experts here can help save lots of time trying to explain at the Dealer. 2004 I35, new battery, 87k miles, runs great once started. Full turn of key elicits a "click" with all panel lights displaying but no turning over. Click only. However, it is NOT the click sound when you have a dead battery. When I turn the key back and try to start again, it eventually will fire like normal... as if nothing were wrong. Now, I'm turning the key in rapid succession 10 or 12 times (this morning) before it will go, and it's now happening at every start... not just infrequently as it has over the last 40K miles or so. Previously, it was pronounced when the car has been idle for a while or on a decline parked position. Computer checks at 40K revealed nothing and the dealer was stumped. ANY advice would be helpful, as I may be stuck at my work parking lot tonight. (NOTE: When I've had a dead battery in the past, I had the "click" followed by the auto seat adjustment (or sound similar); this click is different, as in nothing happens post-click--it either fires, or it doesn't.)

HI I have the same rattling noise on accelleration. I have a 2003 I35 and it has been making that noise since I got it in 2006. I was told it was and octane issue as well, and I tried 93 for a while, and just like you, my car got better, however when gas prices went up I went back to 87 and now the rattle is back..... But now I have bigger issues, My car keeps shutting off... I was told it is a camshaft sensor gone bad... the only thing is they don't know which one so they want me to replace both....
