I was drving aroundabout an hour agoand went to go accelarate and it bogged down. I stopped and smelled the exhaust and its running rich. Its constantly bogged down even when idlingso i stopped driving and left it on the side of the road to avoid any further damage. My first guess is that the timing slipped, anyone else have any theories?

 

what kinds of mods do u have? were u blowing black smoke?

 

Just an intake,clutch adn flywheel. I wasnt blowing black smoke but after it bogged down when I tried to accelarate I got a nice size cloud of white smoke. This happened on my last civic and it turned out the timing slipped along with other things. Right after the smoke I let my foot off the gas, I was still going about 30 in 3rd gear and it stalled. Not like a bad shifting stall just shut down and coast stall.


edit: it doesnt blow smoke at idle

 

it could be a timing problem, thats probably a good place to start.

 

How much white smoke are we talking? White smoke means youre burning coolant.......Did the car overheat? Anything unusual under the hood? Blown coolant lines? No coolant? Pull a plug and see if its white....or maybe just messed up.

 

i also have a 99 si the carwould bog down i lost almost all my power b.c i was burning coolent but there was no white smoke really the exhaust just had a sweet smell the only cl i had was a cylinder misfire so after going therw a full tank of gas in 2 days driving normaly i just pulled my motor and rebuilt now im almost done .

 

Its fixed I had a bad O2 sensor. Turns out it wasnt burning coolant

 

seems like quite the problem for just an o2 sensor....which one was it?
