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?

Outside temp reads icy------ but it is 95 degrees out

This is a new problem,when I hit the gas pedal my car makes a rattling sound, almost like a clicking sound. I need to know if it dangerous. And how long can drive car with a bad tierod.

I have a hard time accelerating or going up hills. If I feather the gas pedal when I'm accelerating it seems to do a little better

My compressor starts cools this shuts off based on the outside temp. And when I increase blower speed it stops blowing cold air.

Replaced brake pads and cleaned the sensors.

I looked in the owners manual and it's coming from the inside after it rains and it's from the fuse box I guess right by the keyless remote insert. And I have some water where I insert my keyless remote to charge? How is it getting into the car?

on the radiator side. The rear will line up but the front won't with out that piece...any suggestions would be appreciated thanks

Today after i got my oil changed and pertol refilled, my Service Engine Soon light stays ON. I got the code from an auto shop as "P0400-Exhaust gas air flow". How to fix this? I checked the petrol tank cap also. It is closed properly.

when i first start my car, it has a ticking sound coming from passenger side of the motor. it somtimes comes and goes. while driving it will shift hard and when lift off the accelorator it slows down like im pressing the brake. But i have changed the alternator 3 times with in 1 year. so i decided to buy a new battery cus i was having to jump start my car everytime i shut it off. but i cleaned the terminal cable connecters and the noise completely stopped but only for a few days. took it to auto zone and they told me i had some kinda of drawl that was pulling power from somewhere when car was shut off.. I really am confused with what it might be plz help me . Also a nissan tech said it was my belts , so i replaced them and nothing changed, he listened for a second and said it was timing chain but will the ticking come and go if it was the timing chain or would it constantly be there. and also will the o2 sensors be a part of the ticking noise?

I have a push button start. It does nothing the key fobs don't work

My car was running fine, until I got my plugs replaced. Then the service engine like came on and it starts up rough and is missing. When I'm driving a steady speed it's fine but when I take my foot off the gas to slow down it has a little miss in it. It occurs Everytime I start the car and Everytime I take my foot off gas to slow down or when going down a hill but not when I apply brake. Please help. I took it back to the shop that placed my plugs and they two plugs were gapped wrong but it's still doing it.

I have to put it in park and rev the engine to keep it turned on. Otherwise it drives fine. Is it a vacuum? Something fuel related? Gasket?

It smells like gas at least once every 30 min while I'm driving.. What could be the problem. How do I fix it and how much would it be?? Please help asap!!!

leaks out from under the middle of the car. There is gas in this leak plus it is very dark and thick. I cannot find any wet places under the car that it has run down on the body or frame. Had it put on a life and could still not see anything even the tech could not find anything. They talked about a charcoal filter somewhere about the gas tank that may be involved. Does anyone have any ideas?


There is a popping noise and vibration coming out of the engine. You can feel the vibration in the gas pedal and the brake. The timing belt was just replaced and the motor mounts are good. The noise/vibration occurs whether its in neutral or drive.

I changed the fuel pump, and it still wouldn't start. Checked the fuel relay and it's good. Spark plugs are still good. What could be the problem?

My car has been sitting and parks for six months I want to jump it and as soon as I put it in neutral and tried you park it into a difference but it did start the next day I turned over the key the windows rolled down but would not start now I am on able to roll my windows or start it what should I do
