My car loses power while I am driving on the freeway, , it always restarts with no problem, but power loss is becoming more constant. Is this a known major problem which I should call a loss, or should I invest in repair? I love my car and I have never had any other problem with it? I was going to give it to my sister, but unsure if it will be a gift or liability?

1998 Infiniti Q45 Question: My car loses power while I am driving on the freeway.
It could be fuel or ignition related. What services have you already done to it? Had a tune up wiht new plugs? Is the check engine light on? Any other light in the cluster on?

I have the similar problem. Lately, the car would just stall and would not move fast enough so I cannot go on the freeways. Can someone please help.

Start your car, and let it idle...raise the hood and locate the Mass Air Flow Sensor (it's under the air filter housing). Wiggle the connector and wiring that connect to it. Chances are you will notice your engine start to miss, buckle, and may very possibly kill. If this does happen, you need to replace the connector, and probably about 12-15 inches of wiring (white,black,and red). I will warn you, these connectors are very hard to find, I did away with the connector by installing 3 individual wires to the MAF connector, MAKING SURE they did not touch, then fill the wire plug with epoxy. Be sure you install the color wire correctly, use your old connector as a guide. I hope this corrects your problem as it did mine. After researching, this is a very common problem. Also, the connector on the ignition coil has a tendency to wear itself out that makes the coil (s) quit firing causing that miss you may feel at a red light, stop
sign, or while driving. I'm almost positive these quick fixes will eliminate your problem. Now there is always the possibility the MAF or Coil can be defective, but both of these wiring problems are very common, and easy to check......good luck
