Ok ive had bad idle problems for like a month now.it is prefect in the cold then when mt engine gets to normal temp it goes to ****. i just recently changed plugs/wires, and i thought that helped it but the next day it was back to doin it again. my car sounds like a v-8 with a big cam in it(only when i have my foot on the gas, if i dont it dies). rpms go up and down and the AFR goes from rich to lean. i havent checked the TPS yet cuz i dont know how. any help will be appreciated.

It sounds like something electrical isn't happening right. Like your fuel pump and injectors and ****. I think it might be your ECU. Dunno I'm a newbie, just trying to give advice with things that I've learned since being here.

Check/replace Fuel Filter
TPS could be out of adjustment
Check/replace SparkPlugs

Check for Fuel,spark,tps,thermo switch connection,vacuum leaks.

ive allready changed fuel filter, sprak plugs/wires. what i dont get is i have great power in upper rpm's. i just cant hold an idle.

Take a good look around for vac leaks...

Do a search for TPS- you'll be reading for days, lol, but you should pick up a good "how to". Or, just use the Haynes or FSM...

If no vac leaks, and TPS is good, get back to us...

Then check for vac leaks and check your bac per fsm.

i was also wondering what plugs i should be using. i have the standerd NGK ones and ive allready noticed that they are as black as the ones i pulled out. should i be using a higher burning plug??
