fast idle / computer problems

i just installed an e cam and replaced the heads on my car(just stock iron heads)

after getting it back together i had a hard time with an idle surge. after reading the idle surge thread i saw that many people have idle problems with the e cam, and i did the iab mod. i then had a fast idle(around 1500-2000) i tried setting the tps and i got .67 volts and the highest i could turn it was up to .75 volts ( i know that .98 is the goal)

i am also having problems with pulling codes. i tried jumping the connector with a wire and it didn't work. i figured i was doing something wrong so i just went out and picked up one of those code readers from autozone but still nothing. i hook it up, key the power on and then switch the reader on and all i hear is a click than the pump cycles again then nothing( i watched it for like 2 mins)

the car is also running really rich

this is my first time trying to diagnosing problems with fuel injection

i tried searching but couldn't find any thing like this

any help will be much appreciated

wow thanks for the info. i got the fast idle nailed down. i went back and reread the how to on the iab mod (i didnt disconnect the iab after modifying it) an just needed to grind it down a little bit more to raise the idle. the tps is set now also( i dont know what i was doing wrong)

i will look into the code issue tomorrow

the resistance between the computer test
ground and the battery ground was .4 ohms

the resistance between the STI connector
and pin 48 was .2 ohms

I tried self test again snd still nothing. Is this a computer problem or is there still something else to check

sweet know were i can get an a9l cheep

thanks for the help by the way
you the man!!
