There is smoke coming from under my hood and a funny smell

It just started when car reached first 100,000 miles

Mass air flow sensor

Crazy loud noise and transmission not wanting to shift gears along with the car having basically no power all happened really suddenly bout two days ago... Replaced the Valve Cover Gasket, Spark Plugs (which the 1st and 4th were full of oil), and O rings today.. still the same problem

all of a sudden switch wont change from a/c vent to floor or defrost

in a day or two, it will start doing the same thing. In order to get it to start, I have to keep holding it down for a while, hold it down again for while until it starts? Is there a recall on this for the 2003 Altimas?

Sometimes, more often in evening when the outside temp is hot, my car just won't take gas when I try to pull out again. No noise, no reving even when I put the gas pedal to the floor, it will eventually pull out. If I turn the ignition off and back in it goes away for awhile. The tank is full, no warning lights on, temp gauge is fine. I've had to to dealer twice, it didn't happen when they test drove it. Said they couldn't do anything if no warning lights are on to read codes.

I don't know what's going on I don't want to have to spend a lot of money what should I do can you please help me

How to replace oxygen sensors

Also, when I drive, it still blows warm to cold air and my temp gauge goes downward, practically to cold setting on the gauge. In the summer with AC on the gauge is right in the middle (perfect). What's going on?

My Service Engine Light continues to turn on for a day or two then off for a day or two for over 2 months. I have yet to figure out why.

Pretty sure it's not the compressor and all belts are fine.

I have replaced coil pack, spark plugs, fuel pump, O2 sensors and still running rough. I checked again and still has misfire code 304. Need Help Soon !!

I've had my O2 sensors, front & back catalytic converter replaced and my alternator replaced. It seems like my take off is a bit slower and it doesn't feel right, what could be wrong with my car? Oh also I have 203,000 miles on it.

I am having a problem with my 2002 nissan altima it ran hot the 1 day and after that the top of the rad blew apart and cracked all the way across the top and then it was blowing white smoke out the tail pipe so I knew the head gasket was bad so that was changed and when it was done did a oil change and filled it up and went to start it and oil was blowing out the filler cap and I put my hand over the filler cap and it has a lot of air coming out of it I had a misfire on cyl 4 and then I moved the coil from cyl 4 to cyl 2 and the misfire moved to cyl 2 so I ordered 4 new coils and plugs and a new pcv valve I checked the pcv valve today and it seams to be ok the hose is not clasped and when I take the hose off it it wants to die not having any luck with it any help would be great thanks

TCM reprogrammed on 2002 Nissan Altima

The car of 2005 altima. Dies at a stop. Why and what would cause that

The water pump had been dripping and yesterday it became a consistent leak I'd say I carry water with me and do check the water and add to it accordingly so going to work this morning went about a mile and a half noticed a hot smell coming through the vents not electrical but hot the temperature gauge was indicating it wasn't over heating then the rpms ran a little and shifted fast just wasn't running like she had been I pulled over turned it off waited a few started it again it didn't want to crank kind of lagged a bit then when it did turn over it revved up to three grand so I just turned it off and here I am now any insight would be a tremendous help

air conditioner and radio both die at same time

I Got this 2006 Nissan Altima and it over heated on me (cause it had a 4" crack in the top front of the radiator that had been previously patched.) I replaced the radiator and now it wont start. I've had a Diagnostic run on it and a person look at it to make sure there was no internal damage from overheating. It showed codes for the crank sensor so I replaced that and it still didn't start.(It did how ever sputter for the first time and almost started.) I changed the Coolant Temperature sensor. I've tried spraying injection fluid into it and it still didn't start. Thinking that would help but nothing. I can hear the fuel pump and after changing the crank sensor i could smell gas. Also before this happened it had a moderate problem with starting. For instance, It would start then immediatly die, then you would have to restart it. it usually started and stayed running after 2 or 3 trys. idk what is going on with it at this point?
