I have a 1991 Maxima SE. 205k miles.

Read the description there.

Can anyone help me out here? Injectors maybe?

I was thinking of running some BK44k and a full tank of gas maybe?

 

that would probably do the trick, probably just a clogged injector or something.

 

It looks like you started the car while the engine is cold. It should be that high when it's cold and the RPM should start dropping as the car warms up.

Did you ever recover the code from the check engine light you got you mentioned in the video description? That may be a start.

Try adjusting the IACV. When I replaced an injector a while ago, my idle would be around 1000 RPM with the engine running warm. I did the adjustment and it's idling fine now.

 

I never did because it's not currently licensed or insured.

I'm not exactly sure how to do the IACV (new to working on cars).

But something tells me its the injectors so I'm gonna run the Seafoam tomorrow, then maybe do an oil change.

 

don't seafoam.
you have no license/insurance, and can't get on it hard. Part of the process of seafoam is to drive the **** out of it after treatment.
and it's a dud injector, dude. just like you've been told in the other thread. unless the injector(s) is (are) gummed up from sitting for years, seafoam/bk44/viagra aren't going to clean a bad electrical system.

(note: not opposed to seafoam, just did it on my car today. just sayin' it won't help the OP, right now)

 

So how do I figure out which injector? Can I just replace one?

 

seafoam helped me
plus new plugs, wires, distributor cap, rotor, etc..

 

Start car and let it warm up to operating temp. Go one by one and unplug the injectors. You should hear the engine idle die a lil. When you hit the bad one idle will not change. For those in the rear under the intake try unpluging corisponding spark plugs. This is how I do it.

 

I was trying but I couldn't figure out how to unplug the injectors

 

just pull the wire for the spark plug. the injectors shouldn't just unplug (a couple of mine do, but like i said, shouldn't), because of the clip that's on 'em.

 

So start the car and for each spark plug wire I pull that it dies a little is the bad injector? Can there just be a few bad injectors (IE only injector 2 and 4 are bad and I can replace those)?

 

No that means that 's a good cylinder that was making power. The one that doesn't show an RPM change are dead cylinders. Test your water temp sensor first is what I would do......

 

Everyone I talk to seems to think it's injectors. I'll try it first.

 

usually it is injectors....especially @ 20 yrs young.....

 

I'm replacing all mine. I don't fell like going back later to do this again.

 

Yep, confirmed. Fuel injector # 2.
