Bogging and Backfire on Upshift

[rico05]

Running rich I assume. Anyone wanna agree with this? I am debating if I want to try and fix it, or just drive it till I get my SR in December. Slight backfire on HARD upshift, and bogging from low speed acceleration (only in first really). I also think my cat is clogged as it gets way hotter than I think it should (glows sometimes). COuld this be affecting all of this? I am prob. gonna yank it and look, but I want a verification first.

glows?? could be a clogged cat... or maybe you are running a tad bit rich.

The popping sound could then be coming from an exhaust leak around the seals of the cat itself....mine has some

if your cat is glowing then it's definately clogged ar at least it's too restrictive.

Those are almost the same symptoms as my 89 f/b. I haven't check the cat yet, but im gonna check it tomorrow because it sounds like a cross between a harley and a go cart.

I think I have a leak, as i can sometimes get a whif of exhaust when sitting w/ windows down. I dunno. I think it is jsut one more thing to not worry about as the SR will fix all;)

Well today i went to a shop and got the exhaust checked. My cat was leaking, thats what was making sound like ***. Now i got a straight pipe and the backfire is very loud. I gotta solve the running rich prob...

If you get the smell of exhaust when you got your windows open, then you have what i got ...leaks around the cat

what happens is once you open the window it relieves the cabin pressure of the car, causing the exhaust fumes to seep up through the shifter area.

Get it fixed soon or everyone will wonder why you stink like exhaust after you drive your car

I get the backfire everyonce in a while on an upshift...i don't smell any exhaust...so i guess shes just running a little rich
