hey guys this morning i was having trouble with my accleration, usally i step on the gas and it flies - but today i would step on it and the rpm would go up to 2 and then i would be going like 5 to 10 mph.

anyone know what the problem would b>?

i checked to see if the trans. fluid was up - or if i had any in there at all - and it was ok - i checked the air filter cuz someone told me it can b that - and i frankly dont think its that -

should i try
fuel injection cleaner?
add more trans fluid?
what?..

anyone know how to drain the trans. and refill it - is there a drain plug somewhere - if so where - and sites/ tutorials?

HELP!
thanks guys

 

um... do you have an automatic?..

=->Evil Twin<-=

 

go easy on that fuel injector cleaner stuff, they're pretty harsh on the injectors themselves and if you use gallons of that crap, you might end up running rich.

i'd check the air filter, exhaust leaks, and the oxygen sensor.

 

we need more info, auto, manual? i had a hesitation problem that turned out to be due to my alternator, so many things can cause this...

 

Has your fuel filter ever been replaced.

 

i have a automatic,

i checked the air filter -
im goin to b changing the fuel filter - tomm or so -
should i just buy a regular filter - or are there like really nice one'z out - that someone may recomend me gettin?

 

So does it seem to over-rev like a worn cluth in a manual...bcause if thats what it feels like I'd suggest getting your tranny rebuilt. I'd check all your filters and fluid...when the last time your car got a good tune up?

 

My shop teacher told me that having too much oil in ur motor can cause it to feel like your tranny was slipping. Actually I'm not sure exactly what it was, but I think thats it. Lol

 

well is your car shiffting? from a cold start up??
-it could be stuck in 3rd gear on a cold start-up
this means you have a lazy tranny temp. sensor
try letting your car warm for a few min..(4-5) then see if it feels ant differnet
-My max has a lazy tranny temp. sensor and i always have to let it warm a bit and got easy when its a cold start-up...so it doesnt hide back in winter mode (3rd gear) it sounds bad, but.. as soon as it warms it feels great.

 

sorry if i'm suggesting the obvious, but its the power / hold switch isn't set to hold is it??

 

yeah i checked all my fluilds and i did another oil change on the car - just to be sure it wasnt too much oil in the engine - but yeah - a real GOOOOOOD tune up sounds goo rite about now -

i think my alternator about to die out too - my windows and everything workin really slow all of a sudden - and im guessin the 2000watts of subs arent helping the alternator too much - specially without a CAP.

wut optima batt. does the 91 take - i think its the red top rite which is equivilant?

 

while too much oil will slow that car down it will also produce white smoke from the tailpipe.

 

oh the optima batt are great go with the red top and if im not miss taken there the ones for evryday car use

but if you plan on doing some heavy off roading with your maxima then go with the yellow top

 

Who in their right mind would do any type of off roading in there Maxima???

 

err power/comfort swtich?

that only controls shift pattern..not power delivery.

 

red is normal use
yellow is DEEP CYCLE...many discharge and recharges and it will not hurt the battery. that's the main differences.

and realistically you can go "off roading" w/ any optima battery..they are all sealed units.

 

Ok, I was thinking that also. Or I just figured I would crawl into my car after work and look for a new power/hold button that I had never ran across. Also, why would anyone need a hold option???????

 

Yeah, and if you throw a Gel Cell battery across the room it won't leak either

 

well it is a car/truck/automobile battery..why would ever need to toss it across anything?

 

While I don't recall seeing a power/hold button on my max. My old legacy did have a hold button for the trans. It was designed to prevent the trans from changing gears when you didn't want it too

 

that sounds like your maf sensor.

 

All I was saying is that sealed batteries are really tough and can take one heck of a beating and not leak. Hense the Optima can be placed on its side or in any other position.

 

I'm guessing you had a problem with your MAF right? Because you've posted this alot lately.

 

do a search on heat soak and you should find your problem

 

Maybe he needs to clarify the problem a little more, because heatsoak would just make his Max a little less powerfull. (maybe 5 - 10 horsepower) I was under the impression that he was having a drastic powerloss. Someone correct me if I'm wrong.

 

well a bad knock sensor could cause the power loss.

Another thing that I just thought of, it could be a loose throttle cable, but it could be alot of things... we always overlook the obvious

 

hey guys - yeah thanks for your help in every aspect - turns out i need a major tune up - showed it to a mechanic friend of mine and he showed me that my wires runin to the sparklugs werent changed in awhile and they were burnin up - so i went ahead and changed all that stuff -and i also changed the fuel filter, everythings is running great rite now - i also - had my sensors tested or wutnot with a friends OBD scanner, and it said everything was good.
thanks again guys - and yeah the post about the off roading with the maxima - funny as heck - lol
who here does that?
im not plannin on doin all that- anytime soon
