running super lean/ temps.

[drunklowlife]

my car was running fine and still is to my knowledge. its been super cold here (15f yesterday and 23f today). im not sure if thats the problem, but when i left off the gas pedal, according to my autometer air/fuel meter it goes from stoich to lean and falls off rapidly. also yesterday i had been driving for 20 minutes and the hot/cold meter as right in the middle and running fine, at about 30 minutes into the drive, it started getting cold again.im running stock radiator, huge fmic, dual electric fans, that are constantly running. and all other common mods.

pffffffft.

that autometer A/F gauge has about the usefulness of lighted valve stem caps.

Narrowband A/F is crap. Get wideband or exhaust gas temperature readings, then report back.

With my A/F gauge, it only reads if the throttle is somewhat depressed. If my foot is off the gas completely, it won't register any reading. Yours might be similar.
