Hi. My 86 2.8sfi is experiencing a rough idle condition when I put the clutch in to come to a stop. Other than misfiring or a plugged fuel filter, does anyone have any other suggestions? Thanks!!

 

Still have a cat?

 

On the chair? Yes. On the car? No. It started doing this last year, before the cat came off.

 

bad vacuum lines perhaps? or a dirty IAC? I had both those problems on my 2.8 and it idled like crap.

 

Oh, I should probably mention:

Custom 3.5" stainless steel intake w/ K&N. 3.5" cat-back exhaust & crossflow muffler, Hypertech thermo-master chip, brand new TPS and O2 sensor.

 

Just wondering why you have a 3.5" exhaust on a V6? Bit overkill isn't it?

 

I like the NoIsE...!

Actually, I was young an' stoopid when I put it on 7 years ago... I was always told: "bigger is better"...

Maybe someday I'll hook the exhaust up to a 393...

EDIT: Oops!!! I went outside an looked at the exhaust again. It's only 3", not 3.5". I think I got a little crazy with the .5's!
