Working on dads 86 Ttype and was all stock 42000 miles, except turbotweak chip and the car was running fine.
I replaced valve springs(comp 980), and removed intake to paint and reinstall power plate, I put in my old Turbotweak 60 # inj. and chip (that was fine when taking out of my car 87 GN) , and RJC 3" downpipe .
I'm now getting codes 34 and 35 before I start it with key on , and after I start it i'm getting codes 34, 55,53,51,44, also the IAC is reading 00 on SM and will not move with any adjustment.
I tried 3 different chips , no change
Replaced computer with known good one
Replaced maf off my car( LS1 with translator) and 3 other stock MAF I had
Replaced IAC off my car(brand new) no change
Change O2 sensor (used but what the heck)
Replaced EST with new one , removed code 42
Cleaned all ECM connection best I could with eraser and contact cleaner
Replace coil pack and ign. module with known good one
Cleaned positive and negative cables on battery
At one time I was showing codes 33,34,41 before I started the car
and 34,54,53,52,44,41,42
Car runs smooth and idles fine , and presently NO CHECK engine light
just codes 34,35 before starting and codes 34,55,53,51,44 after starting ?
Any suggestions ?
