A fluke?

[nhanson]

well i got done with school and was heading home...i noticed the car was doing wierd things...at a stop light it revved before it went into gear and then once i got home it was choking (a put put sound) and then like 5 mins later it was fine!! and the exhaust really smelt of sulfur

Could be an O2 heading south or a catalytic converter clogging.

Sulfur smell is a cat going out. I'm willing to bet that when you mash it, it's sluggish, but if you gently ease into the throttle, it's fine.

if its above idle it was fine...seemed like it anyway

we will see what tomorrow brings...also someone said that i might need a plug change? (its been a year or a lil more)

edit..also no lights thrown at me either

Cat is getting clogged. Take it to your local gm and they will replace it for free.

Does that recall apply to his '98 Monte?

I know I got a letter about it for my '02 GP GT and a freind got one for his '01 GP GT.

we never got a letter...but its any gm dealer right?

[blitzstreik]

Any gm dealer. Replacing cats is free under the emissions laws, at least, thats what I have been told.

I had my cat get clogged last April.

it seems to run fine now any way...and a clogged cat would obviously affect the engine since exhaust isnt passing through very good right?
