well i currently replaced the spark plugs, wires, cap and rotor and when i turn on the car it smells lean and idle is a little higher now(about 1100rpm). before i did the tune up it usually smells very rich whenever i turn on the car. is this normal? btw i just used some ZMAX the very same day of the tune up....

 

Maybe try pulling the EFI fuse for a minute and let the ECU reset.

 

So you can smell if your car runs lean or rich? Impressive!

 

^^^ my thoughts exactly. especially the lean part. if running rich, u can smell gas, understandable. the opposite isn't always true...no smell could also mean u are running correctly, no?

 

You can smell when it's lean...... huh. What exactly does that smell like?

 

lol...i guess it's running ok then haha, but it does have a weird smell to it just doesn't seem normal to me.

 

plug in a a/f meter and it should tell you how it's running

 

uhh..to cheap to buy a wideband at this time.

 

ask a friend? I have a narrow band A/F meter that you would be able to use... but your far away hahaha

 

I dont think it is good to smell your exhaust but i may be wrong. You should get someone to test it.

 

i'm thinking it's just the zmax cleaning the gunks inside the engine, kinda like seafoam.

 

ive been thinking about it for a few hours, and the best way I can describe the lean exhaust smell (been dealing with carbureated rotaries for a while) is it's like burned propane from a gas stove. If you really are lean, then you can tell by the temp of the cats (if you have them or if you dont) you really need a wideband and a dyno. GL!

 

Epic......

 

narrow band af meters do not tell you anything except that the gauge is getting power and now theres a light show in your interior

 

+1 A narrow band isnt gonna tell you crap.
