i bought a 2000 honda civic lx about 2 months ago and it was riding beautifully, then maybe a 3 weeks ago the CEL came on and the code was a p420 or somethin close which came up as the catalytic converter, i got some advice and was told not to worry about it now since the car had just been smogged for the sale, welll all of a sudden when pulling into traffic the car stalled just a bit, and when i'm stopped at a red light it will stall slightly, feels almost like the car is shifting gears or somethin, ive figured out that it stalls when i accelerate quickly (pulling into traffic) or when not in motion at all, even when im in Park. It drives perfect if im on highway or if i accelerate slowly...any thoughts on what this could be??? ive been hearing lots of things from different mechanics, (get a new catalytic converter, clean the throttle body, its probably the O2 sensor, get a tuneup....etc)

i figure someone here can point me in the right direction, please help!?! any input is appreciated

 

anybody encounter this before?? i found 2 posts google-ing my problem but they were old and they never posted what fixed it....please help

 

anything? anybody?

lol

 

does your idle jump up and down?

 

no, rpm's dont move at all, it idles perfect but then it feels like its gonna die or something for a sec and then idles fine, the feeling is almost like the tranny switching gears but its not that, its stalling.....

 

I'm kind of a noob at this stuff but can you tell if its running rich? Like strong gasoline smell coming from exhaust when its running?

 

if it is "running rich" i haven't noticed the smell, but i havent exactly been looking either, im at work right now lol, but i can check when i get off at 2....if it is running rich what does that mean it could be?

 

ok, update on the car, i checked for a gasoline heavy exhaust smell and nope...nothin......someone please help, im getting questions i just some answers please

 

well this happen to my brothers car 2 weeks ago. he changed the cat. and the downstream O2 sensor. both cost him 320 i think is what he told me. not sure where exactly he bought it from but heres one of the place he buys his parts. Rockauto.com

 

could be clogged injectors and/or bad fuel filter. My car used to do this sometimes, i put in Techron (you can buy this by itself) and I got a new fuel filter and it went away. It never stalled on accel tho, it used to feel like it was gonna stall when I was at a light sometimes.

 

ok, sooo im gonna try the fuel filter and techron deal, hopefully that'll do the trick and some me some money
