High RPMs

Keira · Post by **Keira** » February 22nd, 2005, 4:45 pm

I have a 94 GS and im at about 4.9 RPMs going 50 MPH in 5th gear.
Could this be due to the clutch slipping or maybe something else? I hope it isnt the clutch.
Also, my exaust is pretty rusted out and its really loud. I havent gotten it looked at but it seems that i dont have any back pressure.
And... my car is burning gas pretty fast and whenever i check my oil it is low.
So if anyone has any ideas of what could be wrong with it that would help.
thanks

Could it be due to Gearing of the transmission?

It could be a slipping clutch.. but likely you would feel that as well. Does the engine "Sound" like its doing 4900 rpm? I mean does it sound the same doing 4900 RPM in nuetral as it does when you are doing 4900 RPM in 5th gear? Or does it "sound" like a lower RPM speed? Kinda weird to have that high of RPM in 5th gear @ 50 mph.. even with my ATX trans at 50 I am only pulling around 2000 RPM. If the engine doesnt sound like its stressing at all.. my guess would be that your Tach is malfunctioning.. on the other hand.. if it sounds like its doing that RPM.. well it probably is the clutch slipping.

is the 'GS' the 1.8 V6 one?

FYI: I have a 1.8 V6, completely standard alloys/tyres -so no speedo errors there, and its a Manual-Transmission.

I was on the motorway the other day and was doing 4000rpm in 5th gear, at 75mph.

yes, GS = 1.8L V6

Did you ever happen to check you spark plugs???Its a possiblity that your spark plug wires or"spark plug" is actually cracked!!. Give a good look at it,hopefully thats the problem!

hmm im going to try that..also i tought my clutch was goiung..it ewnded up being the kat being clogged..but then again this car has high revs on highway on 5th gear..its normal..when your clutch slips u can feel it..the rps go high high and it smells like burnt clutch or burn smell that is not oil. I find my clutch is fine because i can peel out nicely..so it cant be the cxlutch..im still clueless as to my loss of power..

Can someone clue me in on what "clogs" a cat? Is it unburnt exhaust fumes or something building up in there? Or are we talking somehow dirt and whatnot got sucked up in there?

Woohoo! Fort Bliss, TX! Is the Naked Harem still around?

YA...Don't take this the wrong way, but it appears that you have sadly neglected your car and now that your encountering the consequences you're looking for a quick fix. IMO...find a reliable shop...get it sorted out and ask for a schedule/routine to follow (ask them to show you where and what) as to maintain your car's reliability - welcome to the responsibilities of car ownership.

Wasn't trying to be insulting, but things like an exhaust just don't rust out and get really loud in the first month of ownership. It was either missed while you gave the car the once over or the shop that inspected the car for you prior to purchase. And if you purchased it certified, than for sure a BIG RED FLAG should go up. At any rate, can't change that. You say that your oil is always low when you check it. Does this mean that you're constantly topping it up to the correct level and your losing oil on a regular basis. After driving, confirm by parking your car (for over night if able) on a large piece of cardboard under the engine bay and see what appears in the morning. Have you checked your coolant - level and colour? If it's a milky colour than we're in big $$$ trouble. The reason I asked is that you said you're suffering dramatic power losses at speed. Since you made no mention of possible clutch slippage at lower gears, I'm thinking that it's not the clutch. Hoping that it's not a cracked head or block. Are your valve covers weeping oil from the edges? One at a time take each spark plug out and see if something reveals itself. A little more specifics and descriptions on what you see, hear after you've done this or that - cause and effect. That would be immensely helpfull. Give it a try Keira and good luck.
BTW, if you've only had it a month, wasn't there some sort of warranty - 30 - 60 - 90 days perhaps. If it was sold certified, any mechanical problems encountered within 30 days (?) is the the responsibility of the vendor - I think, maybe the certifying shop??? FWIW

I havent been topping the oil off, i changed it right when i got my car then i took it for an oil change when i noticed that it wasnt staying full, just so they could check for any leaks, etc. I was told it wasnt leaking, probably just burning quickly. I got my valve covers sealed and i dont see anything wrong there. My coolant is ok, not milky or brown, and the level is ok.

Anytime i am accelerating, even softly, i hear that nasty muffler noise and especially when i start my car. Same with when i use the cruise, anytime it needs to maintain the speed it is really loud but then when i go downhill it will get quieter. But i noticed that the RPMs arent constant. When the heat/air is off the RPMs are much lower at high speeds. And after I fill my tank the RPMs are almost normal, it is just when I get low on gas that they are so high.

Another thing that happened when i first got my car is the check engine light would come on anytime i would go past 60 MPH and kinda flicker on and off until i slowed down. I thought, at that point, that there may be a problem between the engine and the exaust system, but i wasnt hearing any sort of unusual noise then.

And I know you werent trying to be insulting but i love cars, especially mine, i would never neglect it.

There we go, I think we're zeroing in on it. It appears that your car may be starving for fuel or maybe, worst case, an obstruction in the fuel line(?). First off, I would replace the fuel filter, something that gets put off or neglected over time, probably because of cost and lack of easy installation. Probably discount faulty fuel pump regulator at this point until fuel filter is changed. If by chance something (contaminant) got into your fuel tank like perhaps a bad batch of gas or that there's an over abundance of moisture that's accumulated over the years into water in the tank. This is why I'm thinkin' that whenever your low on fuel it appears to be worse - your drawing in more contaminated fuel as the level in the tank gets lower. Your improvement in performance going downhill also points at the same thing. At any rate I'm suspecting it's a lack of or bad fuel situation. Try pulling CEL codes from memory when the chance permits. Right away a fuel filter and if you've got a "friend" in a shop smewhere ask if they could draw a sample of fuel from the tank or have the person changing your fuel filter to try and capture a viable amount of fuel from the fuel line. This is a good start for now. Good luck, keep us posted.
