hey so my car just all of a sudden has a huge loss of power and is dumping out fuel i can smell it pretty badly in the exhaust. i thought it was an exhaust resriction but i pulled the exhaust and its still just as bad. and i also just checked my coils and both were good. any ideas???????

Spark plug or wire gone bad? Not sure.. never heard of this.

i figured it out one of the coil wires was bad runs good now. it sounds so mean with the exhaust off i think im gonna drive it with it off for a while

HKSC430

took me nearly 1 year to figure it out with my mechanic...

I had mainly poor fuel economy, smell of gasoline in the exhaust when I floor the gas for nearly 1 year...

my car's fuel economy deteriorated suddenly last summer: averaging 23L/100km...

we had nearly everything looked at and changed: plugs, plug wires, ignition coils, cleaned the throttle body, MAF sensor, o2 sensors, etc...

mine turned out to have bad 02 sensors that didn't trigger the check engine light and mainly bad connecting wires back to the ECU...

now back to about 17L/100km, same as my SC 430 in all-city driving...

so please get an expert to check all your sensors (many), ECU and wires!
