I m new but my auto 95 maxima vibrates when at a complete stop and some times when in motion. When at a complete stop it idles at 400-500, and it just started to do it while the car is moving. I dont know why it happens but it happens at ramdom times.
Can someone please help me before the problem gets worse.
Thanks

 

Any codes?

 

Idk how the run codes? the shop that i go to that has the machine it can only do it for 96+ cars.

I just changed the MAF, and i cleaned the TB and the filter(stort ram)

 

... did you plug everything back in correctly and secure. do you have check engine light on?

 

Yes i plugged eveything where it was suppose to be. I've had the check engine light on since i did my engine swap.

 

Have you tried to adjust the idle? The black screw facing up on top of the IACV. Your idle should be around 650. Get that CEL checked.

 

sounds like your idle might be a little low which probably has something to do with your TB cleaning. figure out what you should be idling at and how to adjust your idle.

May be your engine mounts too or a tranny problem if you have an auto but start with the easy things first.

 

"HELP!" is not an appropriate thread title.

Dear n00b:

Please read the following sticky.

Thank you,

Fellow orgers

 

Idk where the iacv is located but imma look.

 

^^ sry

 

The machine at the shop you go to can do your 95. If they say they can't then you need to find a new shop to work on your car.

 

why 96+ if its because they have an OBD2 scanner arent our maxes obd2? i thought i read somewhere that are Maxs came with obd2 and r134a?

 

1995 Maximas come prewired with an OBD-II port. I believe it is on the passenger side of the dash though...

Try searching for some answers. Your being way to vague.

 

IACV is next to the throttle body. Take it out and clean it first, see if that helps the idle. if it's still low, you can adjust it with the black screw. Check this thread for good pictures that might help:

You don't have to take the car anywhere to see what the codes are. Check it with this method and let us know what you find, that might help shed some light on the problem:

After you have the code, look it up here:

Do you know the current state of your motor mounts? Hear any banging when you shift into D or R?

 

Thanks very helpful links... Now that i know where the IACV is im goin to clean it and the TB again. also im goin to try and see what codes i got and get back with my info.

 

My mounts are good and i swap my tranny in May of this year.. this problem has been happening for a while but it just started to get worse.

 

Hows your tranny fluidÉ (É, thats supposed to be a question mark).

 

My tranny fluid is ok... J/a i got an MEVI but i dont think i have the vac can or solenoid, could this be one of the problems?

 

Not having the vac can and solenoid for the MEVI won't cause the problem your describing, but an incorrectly installed MEVI could. You may have a vacuum leak somewhere now...

 

Ok I just found out the codes.
P1320-coil pack
P0325-knock sensor
P1401-EGR sensor
I think I got a miss fire from the one of the coil packs but don't know which one. I'm going to let the car cool down then check.

 

OEM knock sensor here

I'm not sure about the EGR sensor, it might be the one on the tube near the firewal IDK. check for connections first, FSM or Haynes manual will help

 

^ Is there an online manual

 

Autozone's website has quit a bit of mechanical diagrams/info on our cars.

You can also download the FSM from phatg20.net.

 

my 95 started shakin when at a stop and idle so i replaced the fuel filter,PCV, and went down to autozone and got a fuel system cleaner additive...good as new now even with 93K mi.but yours sounds a bit more serious if your talking about it runnin codes. hope you find the problem

 

someone was selling 2 knock sensors in the sell forum
