fixed the running rich problem

[djalkyd]

well for a few weeks the car had been running extremely rich and everytime i started getting into boost, it would just puff out black smoke and want to die. the turbo would start spooling like crazy even befor one psi of boost was reached.

i went from getting 300+ miles to a tank to getting 130 miles a tank. the fuel was just dumping.

i thought it may have been the HAC sensor because the problem started when i went through the mountains going into los angeles from bakersfield. so if anyone knows that mountain range called "the grape vine" then you will understand what the car was put through.

as soon as i went through those mountains, i started getting real bad fuel cut in 5th gear. then a few days later it started happening in all gears. then a few days later it started running real rich and the gas consumpsion just went through the roof.

i started by checking the resistance in the afm and it checked out fine, but i didn't rule that out. i checked the injectors and ignition, everything was fine there. so i pulled the hac sensor and it was fine to.

it all boiled down to the afm. i replaced it with the upgraded LS400 of course and talk about a difference. the car just runs so much cleaner. the power is back in it even at stock boost. it's not eating so much fuel anymore.

so if your car starts putting around and just runs extremely rich, don't rule out the AFM.

and to supragirl, thanks you very much for all the wonderful advice. you rock.
