My car runs really rich..really really really.....and "misses every 20 seconds or so....rrrrrrrrr pop pop rrrrrrrrrrr..ect
anyways i was wondering if an unusual clog in the exhaust could cause this? One of my mufflers is blown to **** and the other seems to be on the way out too....could "rust" in the muffler be restricting the flow of exhaust and causing the rich situation and poor gas miliage, i have changed everything else....just a shot in the dark...

How do you know its rich? AFR gauge? Smell?

 

My eyes burn when i stand behind it and it smells rich....it's rich...i promise....plus i'm getiing 8-12 miles to the gal.

 

Well, you can turn your idle mix down by following the steps in the FSM. Other then that, your ECU takes over. Had your O2 sensor changed lately?

 

yeah new bosch unit...

 

What are you complaining about getting 12 mpg? Lucky you.

 

are you joking, my 85 gets 6 miles and if its cold i get 8 in the 87.... usually get 8 if it's on the interstate......

 

I get about 10mpg, it would drive me crazy but I don't have enough gas to get there.

 

umm i get 16 the trick is shifting under 3k forever.

 

umm, I have a NA FC and I get around 16 in the city and 25 on highway....on 87 octane, and no I do not shift under 3K either....my highway mileage was figured over an 860 mile trip I took in October, and my city driving is figured every time I fill up. All stock, and I get these numbers consistently. If you are only getting 6 or 8, you have something wrong or out of adjustment. I get at least 300 miles to a tank and almost always more than that....obviously less if I get on it hard but nowhere near the mess that some of you are saying.....

 

Those milages are terrible.

 

bacl to the first question...............could the hypothetical blockage be causing the rich stuation and poor gas miliage?

 

Possible, if the blockage was so bad that it was keeping the gasses back in the manifold area.

Go Crazy? DON'T MIND IF I DO! Wahahahaawooowahaha!

I love that episode.

 

My TII gets 12 city, and about 24 on the highway.

 

same, except i get ~18 city..

dont know why, either. 'guess im just lucky

 

i forgot to mention i get 16 under 3k but i have a one catback exhaust with a streetported engine... lol

 

I got close to 30 on a 300 mile trip, no BS

 

How in the hell do you get 18 in the city???? Do you shift when the arrow tells you to .

I never gotten anything more than 14 mpg. And again, I like to hear the BOOST when I drive

 

me too.. like i said in my post, i really dont know why i get such good gas milage..
