exhaust smells rich

my 90 rs camaro 5.0 liter smells like its running rich
but its not smoking

As long as your 02 sensor is workin.. it shouldnt be runnin rich.. And if it isnt workin your engine light should be on.. But ive seen stranger things

id say thats what it is, i put a new one on the
drivers side manifold, i guess the one next to
the cat is probally bad then, thanks.

I Think that the one next to the cat is just to let you know your cat is workin properly, if your cat isnt workin, it triggers that 02 sensor and tells you your cat is bad.. I dont think the ECM takes any A/F data from that cat..

I could be wrong?

well my check engine light comes on after
driving about 10 miles and wont go off til
you turn off the engine. but it only does it
every once in a while. i run 92 octane in it
to, would that do it.

well the high octane could do it. if your not getting complete combustion then it would smell rich. i would look into the sensor though, and for future reference, unless you got the engine modded and the timing advanced you dont get any real benefit out of running 92 octane...just in case you want to save some pennies...

well if i dont the valves rattle under
heavy acceleration

If your engine lights comin' on.. Thats probably a pretty good indicator that your 02 sensor could be shot.. That or maybe an egr problem thats causing it to run rich..

Scan the ecm for codes and it'l give you a better idea of whats goin on

valves rattling under acceleration doesnt sound good. i would think that you might want to look into that rather than just using higher octane, IMO, granted i dont know much about these things...

A problem with your EGR system will cause "valve ping" and valve knocking under acceleration.. The valve could be slow to open or not open at all.. This could also contribute to the car running rich, And it'l also turn the engine light on after it gets warmed up as you described

ill check it out then, i had figured that the
valves were just worn out it doesnt clatter
when i run the 92 octane in it, i bought gas
for my tacoma today and the valves clatered
a little bit but i put 87 octane in it, i think the
gas stations have been getting bad gas, or
watering it down

thats very likely.. I try to stay away from shady no-name gas stations.. or gas stations that sell that wheat fuel bull$hit, or ethynol..

Scan your codes.. I'll bet it gives you a egr fault code!

like sheetz and wawas!! cheapest gas around here, the only reason i go to sheetz is cause they have some good ass food!!

sheetz and wawas?? LoL what the hell is that? what do they sell?? Linens and prostitutes??

I dont think i could ever by fuel from a place called sheetz and wawas.. For my car OR my belly!!

haha i wish!! nah they sell gas and food, its like a 7-11, a subway and mcdonalds in one store, they call it made-to-order, the subs are good as shit and the fries, yumm damn i might have to run up there, after 4pm a 12in sub is only 4.99!! and gas is like 1.67 a gallon now

gas here is retarded, it just keeps goin up and up.. then down a bit, then up twice as much.. Someone should be shot..

you pay a lot for your subS?? I can get a 12" sub here for 4.99 any time.. canadian dollar

lol, how much is that in u.s. dollear? shit from subway here like 3.99 for a 6 inch, yea i still remember when gas was 1.39 that wasnt that long ago actually.....

its a 1.83 for 87 octane here 2.03 for 92....
its a shame i put $20 in my tacoma and it
didnt even fill it up. id say that this summer
it will be way over that. or around election time
it will go down and mr bush will say that he had
the prices lowered so everyone will vote for him.

haha, they scam us on gas just cause they kno we will buy it no matter how high it will go

i have 2 93 bombairdier sea doo wave runners,
last summer at the lake it was almost 2.50 a
gallon at the boat dock. they dont run that
long on gas either. 2 days at the lake costed
me $90 to run one of them, my brothers
carbarator was down on his and kept shutting
off.

yea jet skis are fun as shit!! i hit 83 on a yamaha, i think it was a waverunner??

i think mine will do about 60mph i'd really
like a new tiger shark with the 4 stroke
deal. but oh well, my mom says that our
yard looks like a used car lot....lol
that firebird i bought will really set the tires
on fire. you should of seen the rubber on the
back side of the car, i dropped the clutch
at about 2500 rpm and nailed it, my brother said
that he couldnt see the backend of the car for
the tire smoke. i laid a 50 ft black mark in 1st,
20 ft'er in 2nd, and 15ft in 3rd. this car is the
bomb. i ve got to go back and get the bumpers
and the ram air hood for it, i run it home with out
a hood on it, it was cool. the ram air scoop
got alot of wind today. the stock fire bird hood
wouldnt close cause the ram air box sticking up.

lol, yea we have 6 cars, the bird sounds fassst, thats y i wanna stick i love throwing gears, and catching them, thats y i wanna get a 6sp, id like to see pics of the car with the swap, sounds sick!!

ill definatly get them on sometime. that dude was
damn good at what he done. it all looks factory under the hood. i need to get a pas. side fender
and get the trans am nose and rear bumper
painted. as for the rest of the car the paint is
in great shape, needs buffed, there are swirl
marks. dont 3m make a wax that takes those out?

umm i dunno about the 3m thing, but ive used rubbing compound and it seems to work good, i have swirl marks in my paint also and its starting to turn an off yellow, but its not bad for the oirginal paint job, and it has no rust, what color is your bird?

i need to wash buff and wax it bad!!

black. with charcol grey leather interior. the front
passenger side rim is scuffed too. ive got
the slp ss rims they have the slp logo in the middle,
do you think they would look good? thier the
5 star, they are silver. id like to find a set of chrome
zo6 corvette wheels for it. i think this car is faster
than the 87 t/a i had with the 383...

i love black, im considering paintin my maro black but i jus dunno, i already have a black truck, i dunno if the slp rims would look nice, im sure they would, but i also like the z06 rims

im going to give the rims a try see what they
look like. my brother laughed and said at
80-90mph whos going to see the little scuff
anyway.

lol very true

a white car can be just as sharp as the black.
i tried out a 87 iroc-z my sophmore year in
high school, 350 tpi, 129,+miles, it was white
with the black and gold iroc stripe kit. beutiful
car. tinted windows, red interior, had all the
options. they wanted 4,200 my mom wouldnt
let me have it, cause it smoked when it started.
i was so sick, i was still stuck with the 91 6 banger
camaro, i wanted to trade it, he said that he could
only give me 1,200 on trade in. it was in just as
good shape as the iroc, newer, less miles ( 94,000 )
thats been 6 years ago. and i still wish i had bought it.

yea im more then likly gonna keep it white, there not many white ones around here, im sure everybodys passed up a car they wish the coulda got, shit i almost had an yellow 82 z with a 350 and a th350 trans, looked nice, the dude just lost the key, 500 bucks!

here's a link to a trans am on ebay, its a 97
with ram air. when i get the 96 front end
and rear on and the hood and fender it
will look just like this one only black same wheels too.

looks sweet, but im not diggin the green for some reason.....

is it just me or does it look lowered?

looks it, and i will never own a green car.
i sold my 87 trans am to my uncle
he gave me 9,000 big ones for it.
he bought it to take to races and car
shows. i come off good on the deal,
i bout the black bird for 2500 and
have money left to play with.
