I saw your post about the tail lights and dash lights not working. I was wondering if you found the problem. I am having the same problem, and went through the same steps you did with no luck. Mine is the 91 Q45 with the same exact problem!!! My climate control works but has no display. My front marker and headlights work but no tail dash or shift indicator lights. Fuses all good, bulbs all good. I am at a loss. Thanks for your time!!!
#829 of 975 HELP - problem with 1995 Q45 running rough
Aug 16, 2005 (11:27 am)
I've taken my car into the Infiniti shop now 2 times and they still can't figure the problem out. They hooked it up to the computer and everything reads fine.
My car will not go when you step on the gas. I have to floor the gas pedal to get it to go sometimes and it revs out to approx. 4000 rpm's. It doesn't do this all the time. I'll be driving home and at a stop sign and it won't go. Well, it goes but not very fast. People behind me get all mad. Other times it flies! My idle seems to be a little low all the time and my air isn't that great when sitting at a stop light. I have to put the car in neutral and rev the engine up to 1000 rpm's to get the air working good. I do have a slight hole in the muffler too but I don't think that that would be the cause. I've put new spark plugs in it, new oil filter and a new air filter. Anyone have any idea what could be wrong with my car?

The problem may be as simple as switching from reg gas to premium gas. I have a 92 q45 and I swithced from reg to premium and my car has a nice smooth take off. Put some gas treatment in the gas to clean out the injectors that also may help. Remeber that the infinity is a luxury car and needs that special attention to detail. As for the A.C. that could be a minor recharging. I hope this information is helpful and goodluck.

Be sure to use BK44 or Techron gas treatment only. You can get BK44 at the dealership for like $30.00. Also, have replace your fuel filter? And check if the fuel pump is noisy?

We've replaced the fuel filter and I do get super gas at $2.70 a gallon! Man is gas ridiculous! Haven't checked the noise on the fuel pump. There is some humming that comes out of the engine. It's odd because all the diagnostics at infiniti came up perfect.

I had a new relay run for the tail light. Don't waste your time and money trying to find the problem. I had a guy spend 3 hours on finding the problem but to no success. I later had a new relay setup and it cost me $80.00. When the tail lights come on the dash lights would come on also. The tail light inoperative warning may still display but don't worry about it. I ignore it. GOOD LUCK!
#834 of 975 Question About Winter Driving in the snow
Aug 26, 2005 (2:42 pm)
I love my Q45 (it's a 2000 I bought 18 months ago). Best car I've ever driven ... but it just doesn't do well in the snow.
I live in New England, and I really need some advice on what to do. I currently have 16" wheels, and 60R16 tires. Any recommendations on what I can do to ensure that this car actually gets me through the snow this winter? I've been looking at Blizzac snow tires, but frankly the problem was so great last winter I'm not sure that's going to help me enough.
Advice anyone? Re: wheel size? Tire size? Make of tire?
Thanks in advance for help.
#835 of 975 How can we save money on gas with a Q45?
Aug 31, 2005 (8:39 pm)
I am a first time driver and own a 1993 Infiniti Q45. Gas now is 2.99 and going up as we all know!!!! What can we do to save gas except for not driving alot. Can we pull out the seats and get out stuff from the car that can decrease the weight in the car? Is there something you can buy to increase your miles per gallon? Please help, Thanks.

#837 of 975 air suspension question
Sep 01, 2005 (8:58 am)
I have the q45a and i am attempting to somewhat modify my air suspension. When i turn the car off the rear passenger side is the only side to readjust. it raises about 2-3 inches, but none of the others shift.
How can i tell if i have a leak in my air bags or if the compression/pump has gone bad? Could it be wiring also?
