#229 of 413 oxygen sensor and knock sensor change by samuelh1 Feb 02, 2007 (10:37 pm)
I have a 1999 Infiniti i30. Service engine soon light came on and took it to my mechanic. He said that I needed oxygen sensor replaced and my kock sensor replaced. I was also told that my gas mileage will be much better after those changes. Now, it's been about 2 weeks and my gas mileage has been worse than before. I know there is no adjustment to make on Fuel Injection cars. Is this normal? Can it be that the sensors, maybe one of them is bad? Thanks
#230 of 413 Electrical Problem Solved / Ghostbuster! by kenny25 Mar 01, 2007 (6:37 am)
I30 saga over several posts. Replaced alternator several times, lead harness, xtra ground cables, fuses, 2 new batteries, etc. Still had dash lights come on and still had a dead car after two weeks. Service mgr at Infiniti dealership said no replacement alternator will make the lights behave except a Hitachi 140amp OEM alternator. I found one on eBay out of a place in California...came shrink wrapped...a sparkling beauty...put it in...NO MORE PROBLEMS! Car is happy, wife is happy. All is good!
#231 of 413 Screwed Up Antenna!! by jimathen Mar 01, 2007 (7:14 pm)
I have a 1999 Infinity i30   Everything in the car works fine except my antenna. Every time I turn the car on and off, an odd clicking, almost grinding noise comes from that area of the car. Oh yeah, the antenna never goes down either. Can someone explain to me whats going wrong. Is it the motor? Or is the antenna just off track? And if anyone can explain to me how to fix this problem i would really appreciate it. Thanks Replies to this message: trickplay461 (Apr 13, 2007 6:56 am)
#232 of 413 Ignition Coil Problems by finball Mar 01, 2007 (9:15 pm)
Hello- New to the forum and wanted to say that I have a 2000 I30 that I've had since it had 11 miles on it, picked a titanium gray one right off of the dealership lot and I have to say that this is the BEST car I've ever had. It's never given me any problems...until now and since i've reached 102,000 miles. The #6 Ignition Coil has gone bad and the car starts but after a while it stutters and does that for about 10 minutes of initial driving. I had it checked out by my mechanic(warranty ran out ) and he came up with an estimate of $221 parts and labor(part being $136). I found the coils at Auto Zone, 1-3 $65.99 and 4-6 $69.99. Only problem now is getting it replaced...I noticed a few mentions of self-install. If anyone could help I would greatly appreciate it. Thanks

Replying to: sr1nath (Jan 29, 2007 11:39 am) Hi sr1nath-new brake job should cost around $450, I know because I just had both front and back done. Pads and rotors for both, hope that helps.
#234 of 413 Ignition coil replacement by marbil Mar 12, 2007 (6:20 pm)
Replacing an ignition coil is very easy. For the front bank of cylinders, you just have to remove the large grey plastic cover (with Infiniti logo) that hides the coils. The front three are lined up in a row. A grey connector with green release tabs is plugged into the side of each coil. Remove the connector and then the remove the bolt holding the coil in place. Grab the coil and pull up to pop it loose from the spark plug. (Just like you would remove an older type plug wire). The ignition coil has a tube attached to it. This is a removable connector that connects the coil to the spark plug. Pull it off and pop it back on your new coil. Insert the tube with the new coil attached into the spark plug hole and push until it pops back on the plug. That's all it takes, and, you just saved yourself about $150 in labor charges.   The rear three coils are not covered. (Note: they are a different shape than the front coils) They're just a little hard to get to. The removal process is the same. Just note that the connectors connect to the top of the coils, not the side.   The bank number of the defective coil should be identified when reading the trouble codes. If it's not keep driving and read the code again after the next occurrence of engine misfire. )That's how I was able to get the bank number for my defective coil.

#236 of 413 Warranty coverage by tlee Mar 20, 2007 (3:16 pm)
I have a certified I30 which is covered under a 7-year, 100,000-mile warranty. The "service engine soon" light came on the day before yesterday. I made an appointment with the Infiniti dealer yesterday and brought the car in this morning. It turned out that the oxygen sensor needs to be replaced. The dealer said that the O2 sensor itself is covered under warranty. However, in order to install the new sensor, the dealer said a new computer program has to be installed, which is NOT covered under warranty and will cost me $120. To me, it doesn't make sense at all. If it is required, shouldn't it be covered by the warranty? I suspect the dealer is just trying to squeeze some extra money out of me (in addition to the $50 deductible).   I've seen many times in Acura, BMW, and other forums that people are routinely getting free software upgrade during the warranty period, especially for first-year models. So, I thought it should be free of charge for Infiniti as well. Does Infiniti always charge customers for software upgrade even during the warranty period? Please help, thanks.   By the way, the dealer said there are 4 oxygen sensors in the I30. Is it true?

Replying to: tlee (Mar 20, 2007 3:16 pm) I have a 1999 infiniti. The engine light came on about 2 months ago. I took it to my local mechanic. Found out that I needed to replace my knock and oxygen sensors. It cost me about $550.00. However, there was no need to upgrade computer program. Like you said, most probably they're trying to make some money. Dealers hate to see when you go back with Powertrain warranty. I just took my other car to the dealer for powertrain warranty job and they tried to do the same. I was firm and that I told them that I was going to call the manufacturer and they got everything done for $0.00. Good luck. Replies to this message: tlee (Mar 21, 2007 4:00 pm)
#238 of 413 Re: Warranty coverage [samuelh1] by tlee Mar 21, 2007 (4:00 pm)
Replying to: samuelh1 (Mar 20, 2007 7:45 pm) Thanks for the info. I called the manufacturer and they told me that there is something called "long-term emission warranty" which only goes up to 80,000 miles. Since my car is over 80K miles, it is not covered. The problem I have with that is, when I bought the car, they didn't say anything about it. And it's also not mentioned in the certified pre-owned warranty. Furthermore, I don't understand why the O2 sensor is covered by the pre-owned warranty but the computer program update is not. It seems to me that both are emission related.   Anyway, since it's no use to argue with them, I just told the dealer to replace the O2 sensors without the program update. I have taken the car back from the dealer this afternoon and everything seems to be fine so far. However, I think I'll never buy another car from Infiniti. Previously, I've been thinking about buying a new G35 or M35.
