Infiniti Q45



  • tegacaytegacay Posts: 1
    I have two 1991 Q45's. Actually one is a Q45a.

    I would like to take some things off of one and add them on the other.

    1 - Is it possible to take the 10 CD changer with the control built into the center console out and install in the other?

    2 - Also, neither drivers power seat controls work. Does anyone know the best way to get these working?

    3 - How do I take the wood grain off of the instrument panel and put it on the other car?

    4 - Finally, when I turn I get a pulling of the tires like the power steering has a catch in it. It does it whichever way I turn and although it does not cause me to lose control it is a gentle jerking feeling.

    Thanks for any help

    I have a 1995 Q45 and it seems to studder and or lag when riding down the road. I have been told it may be my fuel pump, fuel system modulator (computer), spark plugs, injectors, fuel pump relay, fuel injector relay. I have cleaned my fuel system and changed the fuel filter and air filter, to no resolve. Can someone help me in the resolve of my problem, at least lead me in the right direction. I'm getting tired of riding down the road as if I'm bucking on a wild horse, plus my dates are very uncomfortable.

  • I have (3) 1994 q45's
    I think you have to send to clean you "air flow" meter that's what my garage "friend" told me he did
    Great cars

    You know what yall, i just got a Q45 with 146k miles for $2k. And i think its a good deal because nothing is wrong that i know of so far. But now, im pissed,c ause the dealership is telling me 140$ just to raie hood and put on computer. I was like hells naw. But i need to know what would cause a slip light to come on and what would cause the TCS light to stay on and not come off. And also, What will fix that delay in acceleration. That getts on my last nervers. It studders like i put bad gas, but im using super, then wen i mash the gash to pick up sped quick, it may go up to 4000 rpm then will immmediately come down to 2.500 rpm. So what to do?

    I have 1997 Q45 and overall it work perfectly well. It has already gotten around 120,000 miles. Just recently a power recliner switch on the right front seat stopped to work. The seat is in a very inconvenient vertical position, and I cannot move it manually. At a dealership I was told that one of the seat's motors that reclines the seat is broken. To replace it, I would need to pay around $500 including labor. Any suggestion on how to reduce this cost? Where I can buy this motor myself? Is there any way that I can move and recline seat manually?
    Thank you in advance for your help.

    :cry: Hi, I am new to this forum and found you because of a possible serious oil consumption problem. I have a 2002 Q45 that I leased for 3 years and have since purchased because I truly loved it. It is spacious, runs so well. luxurious and still gets heads to turn (I believe those unique headlights bring lots of attention to this car). However; recently I have encountered an oil consumption problem. This did not rear its ugly head until January of this year. Has anyone else had this problem with this engine?

    I have a 1998 Q45 with an in-dash CD/Radio/Cassette combo. When I put a CD in, it tries to read the CD and error comes on. Can anyone give me some direction on how to solve this problem?
    Thanks in Advance

    I have the same car. The way to fix this problem is to replace the Air Flow Sensor which is located on top of the Air Filter. The part can cost from $275 to $350 plus the labor which should be about 1 hour. In addition you should also make sure the Timing Relay Control and the Throttle Body is adjusted accordingly. After these repairs are done your car will drive like new. But start with the Air Flow Sensor first. :D

    i had the same problem. i replaced the air flow meter and the fuel box in the trunk behind the back seat. this cleared the stalling, however, i cant get power to the fuse for the engine control under the hood.

    I'm sure glad that I'm not the only one that has this problem. I bought a 90 Q45 originally for the girlfriend. I have a 90 Saab 9000 turbo & it get's me around fine. I found the Q45 to be a lot of car for the money, but then the stalling, suspension, loud fuel pump etc. to be more than my girlfriend could bare. I told her I would sell it.....UNTIL I DROVE IT!! I am going to find a way to fix this car, because it runs like a raped ape!! Another thing, do the turbonators really work?

    Hi board
    I just found a 1997 Q45t, very impressive car. It has 130Kmi on it. It's offered for $6500 but needs some minor body work (trunk and left side have been keyed), and brakes and tires. Other than that, the car is in perfect condition. I was planning on buying the car in the next couple days. Does it seem like a good deal? Anything in particular I should look for before buying the car?
    I really appreciate everyone's help...

    Thank you,

    Can anyone help me with wiring the plug on the fuel pump control unit (situated under the center of the parcel tray in the boot). I bought a 1991 Q45 front cut to use the engine in a Fiat 130 Coupe. I have just aquired the fuel pump control unit but I do not know which wires go were on the plug.

    HI i own a 1999 Infiniti Q45T with a 4.3 liter engin. could anyone plz tell me the HP of my car, i can seem to figure it out? thnx a lot
  • patpat Posts: 10,421
    According to the specs reached from this link it's a 4.1 liter engine with 266 horsepower.
  • mrinfinmrinfin Posts: 2
    yea but mine has a 4.3 liter, any idea on that?
  • sysadbsysadb Posts: 83
    To my knowledge Infiniti does not make or use a 4.3 liter engine. If you somehow have a transplanted or modified engine there's no way for us to tell what hp it has..

    Just wanted to know if you found your problem? I had the same symptoms and replaced the Air Flow Switch to no avail. Still stalls out at 3-4K. The code box under the right hand kick panel points to several parts, but a man can go broke replacing each one until the problem is solved. If you need to change spark plugs be ready for a job.

    Just wondering if you found out what was up? My '92 Q stalls and dies when I go to stop, to turn into a place; or when I'm just sitting there. I thought that it was a fuel pump but on full exceleration, the engine doesn't starve for fuel. I noticed that right before it stalls the little diagnostics screen reads low battery charge. The fuel filter is brand new and I also noticed that when it starts to stall, I can put it into neutral and the engine picks back up and runs fine. ??????? please help or send me in the right direction. I'm new here and need help. later.

    Hi all,
    I just had service done to my 93 Q45. The mechanic replaced the coil boots and air flow meter. the car runs 90% better now the transmission is not shifting. It will go into reverse, neutral and drive, but when I down shift nothing!. the car was shifting before I took him the car. Is there something that he left unplugged? I don't want to get ripped off when I take him back the car. Can anybody help me??

    Hi Tony, welcome.

    You might want to also post that in our Electrical Problems discussion - someone there may have a thought for you.

    But please unlock your caps key - it looks like you are yelling at us :) and it makes your post difficult to read.

    I am trying to decide among a new Q45, LS 430, and Audi A8. I am mainly interested in comfort and lack of noise, rather than performance. Also, by way of background, I have a 1994 Q45 which I like a lot, but I have had terrible experiences with one bad dealer and, more to the point, with Infiniti/Nissan USA. Is the latter any better than it used to be? I would appreciate any thoughts on either issue. Thank you.

    Even though you aren't interested in "performance" per se, you'll want to peruse our Luxury Performance Sedans discussion. Those are exactly the sort of vehicles that are under discussion there. Have a look while you wait for responses here.

    I have a '94 Q45a with electronic suspension. I bourght it used. From get go it never ran right, as far as the suspensiion goes. Every now and then the suspension goes down whilst driving; the the traction and sliip light comes on, and it's bumpy. How involve is it to change over to regular suspension.

    Buzzby. :confuse:
