A lean night!

What are some culprits that would cause your car to run lean, and if it is running lean is it horrible to drive with it if you dont see any problems arise I.E. horrible for the engine?

How do you suspect your driving lean?

[kulluminati777]

this might sound dumb but when i stand behind the car the exhaust has a over burnt nauseating smell to it and it seems like its not supposed to smell like that or at least i didnt noticed it smelled like that before....and i know its not rich cause my mx-6 is running rich because of an ignition problem thats been a thorn in my side for 6 months but thats neither here nor there lol

maybe it's your cat gone bad? That can cause a rotten eggs smell...

you know how its lean?.. if you get on it and its pinging

goto a shop and get them to run a 5 gas analysis on your car, they can tell from that if its running lean or rich... and yes running lean can be quite dangerous for the engine, depending on how bad it is...

Probably running rich lol. I was running rich and I the engine felt like it was running lean and hated being revved high. Coolant temp sensor was shot. Changed it and it went harder, smoother and got better fuel economy...
