hello my 95 maxima is running pretty badly i think its the spark plugs im not sure anyone got any ideas?

 

Have you checked your flux capacitor?

 

Probably low on blinker fluid.

Seriously though, we need more information. Does it run rough at idle, cruising speeds, hard acceleration? Check Engine Light on? Any blue or white smoke out of the exhaust?
Running rough could be a whole slew of things. Spark plugs, coilpack(s), injector(s), bad MAF.

Start by pulling your plugs and inspect them. They will tell you the health of what's going on in each cylinder. Then report back.

 

+ 1 regarding what wizard said.

remove the spark plugs.

keep track of which plug came freom each cylinder.

show us a clear close up photo of the electrodes.

Many of us can "read" spark plugs. Their color, texture, and electrode gap tell a lot about what's going on in each cylinder.

you need to replace with NGK plugs. They work best. Copper ones are ok. Platinum will last 60k miles. No need for iridium.

 

I just experienced a stumbling acceleration and stumbling during high cruise speed....I got a code and it was the MAF sensor anamoly...So I decided during my trip to Pearsall, Tx to swing by Wrench A Part outside Austin, Tx and I found 2 MAF sensors for $21 each. I decided since it started to down pour due to Tropical storm Hanna closing in to hold off on replacing the MAF. The car was running fine and I went to accelerate on to the highway and it won't do crap and cut off. So I pulled over past the parking lot found a big tree to cover me from the down pour changed the MAF sensor, cleared the code and the car performed really briskly! I drove from Austin to Pearsall back to Austin to Marble Falls back to Columbus and finally home to H-town no more issues!
For Post #1 you need to find out what system the problem is in? Ignition, Air, secondary air, Fuel, etc....Did it cause a CEL (check engine light)? Get under the hood and look for any visual sign of trouble, crack air hoses, loose unsecured connectors, bad wires, etc...Pull your codes and see if anything was stored...GL. I would start by using an ole timing light to check each coil pack for good operation.

 

I will send a video in the engine shakes and inside the whole car shakes. When I try to start it it starts up then tries to stall until I put the gas down a bit then it ideals

So it does idle if you put your foot down on the gas pedal?

Does it idle OK if you do that?

 

it idles but it takes a second to get the RPMs up

 

Get a code reader and read the OBD codes...... sigh!**#%!

 

 

 

got these from the blinking lights

 

you have some generic codes and some specific ones. speed sensor, injector or cylinder 5 fault, etc. look them up using google.

 

You can buy a code reader through Amazon for about 20 bucks. It connects wireless with your phone or computer. I use the BAFX model.

Your next step is to look up the codes on the Web just like we do.

like this : obd-2 code P-××××.

The Web will tell you which specific code means what.

you replaced spark plugs. We need to know which brand you used. Our car does well with NGK.

you have misfire in two cylinders. Probably from bad coils. Our cars like certain brands.

learn how to move coils around. If the codes move with the coil, the coil is bad. It's also possible that you have fuel injector issues.

please look up what the codes mean

then post both the code and it's meaning.

as you can see already, replacing the computer is not the problem.

don't just replace parts at random based on guess work. That gets expensive quickly.
