before this would happen once in a while but not its becoming consistent.

i would press on the gas peddle(enough for it to go up to 3,000 rpm) and accelerats fine up to 3k rpms, but then rpms jst keep on goin up to 5000 without me puting more pressure on the paddle and theres no extra power, or acceleration.

what could this be? ive replace the spark plugs and the oil filter but the problem's still there

is the transmision slipping or might this be the knock sensor?

please help

 

If you're auto then you may need some tranny fluid or just have it flushed all together. Low fluid causes it to slip and do that. Tranny may be going all together. IF your stick, have your clutch checked out.

 

im auto and jst had my trany fluid changed 2,000miles ago,, ima check on its levels though,

 

ignition coils?

 

I don't think the RPMs should be climbing w/out the pedal being depressed further - if they are, it could be yuor TPS... I don't think bad coils or anything like that is going to cause RPMs to climb if the pedal is not being pressed further - not even related. Either you are pressing the pedal and not noticing it, i.e. you might be pressing it enough to get to 5k, but only feeling acceleration until 3k - in which case it would be caused by a slipping tranny.

 

sorry, but what is TPS?

and no im not pressin the peddle further, i mean like i kno the levels of how far to press the peddle since im used to this car and have been drivin it for some time now, but this problem used to apear only on in the mornings after cold starts but now its more frequent,

i can even press on the paddle and the rps climb to 6,000 rpms n still no real power , like the engine is jst makin that noise.

 

and ive also heared that something similar might happen if the ecu goes in to a safe mode for some reason, could this be the case?

if so , what could be causing it to do so?

 

ok, i jst read on the symtoms of a bad TPS, and it says the problem does not appear while the car is accelerating, and the knock sensor give bad acceleration bellow 3,000 rpms so that rools those out

The problem is acceleration above 3,000 rpms.
other than the tranny slipping, what else can it be?

 

I think your transmission is slipping from all your symtoms. Try this - put the car in 1st Gear - i.e. not D, but the 1 position, now try to accelerate to over 3k RPM - accelerate slowly and see if you get power after 3k. Now repeat the test, but once you are moving, shift from the 1st Gear to the 2nd Gear (yes, you can do this while the car is moving). Repeat the test. Now try both tests again but step on it (be careful not to redline it when you are in 1st or 2nd - remember the car WILL NOT shift for you when you are in the 1st or 2nd gear spots).

Report back your findings.

 

ok, just came home from tryin all those things.

Put my car in first, acceleration from a stop was ok till 3-4k rpms, but the rpms kept on goin up untill 6k n up without me puttin anymore pressure on the peddle with no added acceleration. Like before i would have to actually press in the peddle a pretty generous amount for the rpms to go up so far.

Pretty much the same happened in 2nd gear from acceleration from a stop.

When i tryed shifting just like jnmodi said this happened: as i was in 1st gear and the rpms reached 3.5k, i swiched to 2nd , put my foot back on the paddle n pressed it. the rpms went up and the car was just making noise, there was barely any acceleration.

im really clueless right now. is it still the trany?
or what else can it be?

 

sounds like the tranny... 5spd swap ?

 

haha,, i dunno about that one. but i need to be sure its the trany b4 i put lots of cash into it.

But if its the tranny it wouldnt be acting like that in 1st or 2nd would it?
because the rpms are just goin up with out me aplyin extra pressure on the peddle.

 

I just read your post with the results of trying out the various things I suggested. I just had another thought... lets say you are pressing the pedal enough to get to 3k, but instead the tach climbs to 6k, but you don't feel any additional acceleration after 3k right? What happens if you do press the pedal at that point? What I'm getting at is maybe your tach is busted and its showing 6k even though the engine is really at 3k... do you hear the engine reving up to 6k when you see the tach keep climbing? if yes, then you definitely have a slipping transmission, because it means the engine is turning over, but the tranny is not keeping up... if however you just see the tach climb, but the engine sound stay the same, it could be just the instrument cluster (tach).

 

yea, as the rpm's climb the engines is makin more noise n revin higher.

but if i stay in 1st gear and the same thing happens, doesnt that mean that its something other than trany, since the trany just stays in 1st?

 

no it just means that the clutch inside the tranny is slipping.. the bottom line is if the engine spins faster the car has to accelerate - if it is not accelerating, then something is slipping and in your case its the transmission. I would call around and see if you can find a low-mileage auto to just swap in rather than try to find a shop who knows how to rebuild... unless you can get the name of a competent shop off someone around here.

Good luck and keep us posted with your findings.

 

alright, thank you very much for your help. greatly appreciated.

Also, the problem has become as i worse coming back from work, i stoped at a red light, hit the gas as the light turned green and all i got was the rpms goin up and no movent till the rpms hit about 2.5k rpms.

will definetly start looking for a tranny and a shop.

also, njmodi, are u close by glenview? what is there to do arround that town?

 

1/2 hour away from Glenview... there is a really nice mall - Old Orchard - its quite a ritzy area and the mall reflects that. Not much "happening" stuff in the burbs' (in terms of night life) - but you'll only be 1/2 hour from the city and there is plenty there.. PM me with what sort of time/interests you have and I can give you plenty of ideas (zoos, comedy clubs, etc.).
