I have been having these damned tps problems since i put my 54mm tb on (before the heads/cam etc) i checked the voltage and finally got it to .54v-4.9v by unscrewing the idle screw on the tb here lately the car seems a little shaggy my idle has gone bad again sometimes its so bad that when i put it in gear the car just dies.. Well it set the code for tps low voltage again.. and i have again unscrewed the idle screw thinking it may have just got shaken in more.. It seems to have helped a little only problem is now the car idles fairly high around 1100 when the car is in park and when i come in from a drive and park it the car idles around 1300.. Can someone give me some suggestions on what to do about this? btw the idle is set to 1000 in the computer
