I got the code 41 taken care of and thanks for everyone here that has talked about the simple fast quick fix for it (was great!) I however think the car runs like 85% better because this but its still not all the way right, when I come off a exit ramp or onto a curved ramp onto the freeway (the car tries to stall or acts like its out of fuel) the cars hasn’t stalled yet, I always let up on the gas and it comes back to before long) How would I go about hunting this down with no SES lights?

Thanks again

Check the fuel pressure. You may have a clog in the system, or need a new fuel pump. Otherwise, does it run smooth while cruising at a constant speed?

Well the car seems to idle correct, I do think at time I feel a slight miss while cruising (could be the difference in the type or cars I am used to however) I know that my Maxima is a Gxe with the SE package as I have stated before and it only has 160hp and 180TQ with a smaller 3.0 sohc motor with a auto also and the maxima would blow the Bonnie away at any given time, so I would think that something isn’t just right still. I am going to go ahead and start with the typical basic stuff anyhow not knowing what’* been done and hasn’t (plug/fuel filter/air filter/all flushes and then see what’* up with her) My friend that had the 89 I always noticed how nasty his coolant stayed and now mines that way. I think a flush of that will be the first flush and then the trans next brakes and power steering last. Once the car gets above 3,000 rpms it seems to have a good power from there to the 5500-6000 it shifts at when it’* held down.

I am still chasing down my dome-map light issues as they don’t light up when you open the door and not even by the button, but if you start the car and then push the button they will work cant use both at the same time as they dim out a lot if both are turned on together. The lights at my car locks on the outside don’t seem to be working as well as the security light and alarm isn’t working either (hope it’* the stuck rear door) will get around to that maybe this next week.

Thanks for all the help

I'm chasing a similar stumbling issue. Does yours happen mostly with half a tank of gas? Mine does.

Is the stumbling a result of turning or slowing to a stop?

I can't answer for the both of us, but if we're having the same issue, turning no, slowing to a stop yes. Idle will be completely perfect - you don't even feel it and it'll be silent.

Hit the gas, revs go up typically, but before they hit the sub-2000 rpm stall-speed mark or whatever, chugchugchugputt, give it more gas and it get better, and then you slingshot out of the hole because your foot'* down and the hesitation stops. Fuel pressure may be to blame.

also, more recently, when the car'* been hot and on a longer non-highway drive, it'll act really funny. There'* a shudder/refusal to kick down on heavier throttle. Engine shakes and shimmys (you really feel it with bad engine mounts) does a silly dance like it'* bouncing off a 3000rpm rev limiter as seen on tach.

My '91 SSE has been giving me the occassional 'shake' also. My truck used to do it too, until I had the fuel pump replaced.
(I had a shop do it because it had over 30 gallons of gas)

My car does it when it gets lower on fuel also, I am guessing that we have fuel issues thus far and was what I was leaning towards also, mine dont chug from a stop or dont chug when coming to a stop, but you can tell the car holds bacj untill I rev it to 3 and above and then the car takes off a lot better still not what I would expect tho after driving many 3.1'* that seemed to run a lot faster and harder than my 3800 is doing! Mine does it mostly if I am into a curve or on or off a freeway ramp and trying to drive the car sporty! I know this car can handle really well from what I have been able to do so far and I am very impressed with that it rocks so far!

Thanks guys

Think the first thing I would do is to hook up a fuel pressure gauge. Clogging fuel filter would be felt most under load/high rpm.

My LeSabre exhibited the same issues, so I changed the fuel filter, and the strainer on the bottom of the pump. I actually put the filter on backwards, and for some reason, it ran better.
