Hello,

I have yet another question about my max. It is a 2k2 GLE and I think there is something wrong with the RPM. When I am going 70mph on cruise, the RPM is almost 2500. When I compare this with a piece of $%#% Alero, that car does 70mph at about 2000 RPM. Higher RPM is causing more vibration in the car than what I would like. Just picky I guess.

The stealer..ooops..excuse me...dealer told me to do a throttle body clean-up.

The other thing I noticed was that from the twin exhaust pipes, all exhaust gases appear to come out of just one. The dealer said, if the engine light is not on then the oxygen sensors(??) are not picking up anything unusual. Till the light does not come on, there is not much they can do. I dont know if the two problems are related?

Any suggestions or comments?

 

Apples and oranges, man. Yours might just be like that. Deal with it.
A throttle body clean-up may help, I doubt it though. The RPM you sit at a certain gear is dependent more upon the transmission and drivetrain (gear ratios, etc.)

As for the exhaust pipes, that's also the way it is--our mufflers are a "Variable Capacity" type, where only 1 tailpipe is used until the exhaust backpressure rises high enough, in which case the 2nd one opens up (allows decent low-end torque, but opens up for more horsepower when we need it).
It's a very nice feature, not a problem

 

My Max is the same way. Around 2.5k rpms @ 70 mph. I prefer it that way, easier to accelerate at highway speeds from 2.5k rpms. You're muffler seems ok. On the Max, there is a valve in the muffler. During normal driving, exhaust exits out of only one of the tailpipes.

 

LOL....ahh, another satisfied previous alero owner huh?
How many problems with yours did you put up with before you decided to get rid of it?

 

don't feel bad...the Lexus IS300 rests at a comfortable 3000rpm at 60mph...maxima needs at least 80-90mph to reach 3000rpms.

 

Does the alero have the 3.8? My bro has a 2000 3.8 V6 camaro... everyone please stop laughing... and it cruises at 70 mph at around 2000rpm also.

 

and a honda is at like 10k at 60. its all on the engine and gearing. my max is alot quiter at 70 when its at 2500 compared to my old tbird which was at about 2100.

 

Base models came with a dohc 2.4l with like 150hp/155tq (later models had 2.2 I4 with 140hp/150tq) . Mid and high trim levels the GL and GLS get the 3.4 (ohv I believe) with 170hp/200tq. I know 3.8l in camaro makes 200 hp.....not sure on tq.

 

err....... my tach is around 3k when im around 70mph....3.3 around 80 mph...

oh.. mine is 5spd btw

 

dang... ur rpm is hella high. For me: 70 mph@2700, 80@3100. But before i put all that crap in (y-pipe, k@n cone, GAb, blah blah blah) i was hitting 80mph@3000 exactly. Well, at least when you shift down to nuetral while cruising your tach doesn't stay at 1100pm.

5 speed also.

 

mine's auto thats prolly why...taller gears and whatnot...wish i had the 5spd tho...=(

 

some 6spd guy said he cruises at 80mph@2500rpm. Now thats beautiful.

 

i heard that on the 6sp the tach sits at 2200 when they go 80

 

<-- 6spd

60MPH in 5th Gear 2500RPM
60MPH in 6th Gear 2000RPM

80MPH in 5th Gear 3000RPM
80MPH in 6th Gear 2500RPM

Around 90MPH~100MPH in 6th Gear 3000~3200RPM



As you can see 6th gear is definitly a Over Drive gear for fuel economy, and probably 5th gear too.

1st gear doesn't really do anything since its so short, just get the car moving. 2,3,4 are performance gears.

 

and it is a beautiful thing
