ok, heres the story.

today i drove about 15 miles away to a friends house. when i got there i turned my car off. went and got here and tried to start my car and all it did was crank. i removed a few plugs to find out they're all fouled (very dry and white) so i guess i'm running lean.

i find somebody near her that has a set of used plugs from his 350 that are in much better shape than mine so he gave those to me. i managed to install 5 of them. then it was a B***h to start my car. but after i finally got it running, if i gave it more than 1/4 throttle it'd bog out and die. so i managed to get home (stopping at o'reileys to get new plugs first) i bought 8 AC delcos and installed 7 of them tonight (broke one) (gonna go to wal mart llater to get one) my car starts right up now. but it still bogs down whenever i give it more than 1/4 - 1/3 throttle. and if i dont llet go of the pedal it'll backfire.
after i put my 7 plugs in i took it for about a 2 mile spin, then iwhen i got back i pulled the #1 plug and it looked as if it'd been running lean. both of my injectors are spraying just fine (TBI) and i can hear my fuel pump running.

the car revs just ine in park or neutral, no bogging at any rpm nomatter how i push the pedal (push fast, slow, relese fast, or slow.)

what could be the cause of this???

BTW (i'm gonna post on the general eninge and TBI boards because i need an answer tonight. this is my only car and i have to be at work tomorrow morning.)

 

You're obviously running really lean. Don't drive it like this. Look at the fuel injectors and flick over the TPS sensor, NOT the throttle. Watch to fuel being injected, it should be a lot, if not, replace fuel filter. Then if that doesn't work go on to the o2 sensor and if that doesn't work have a shop check the fuel pressure. That's the most commen problems when running lean.
