I put 90 Si Trans, Intake mani., ECU, Dizzy, O2 sensor, Throttle cable and wire harness on my 88 STD hatch and the car feels Very strong and can't wait to get the cam out of the Si head and put it in the D15b1.

Only problems are at WOT The car studders and wants to die.

Also codes 4,9,10,14,and 20 are still flashing. . . . . Kinda weird that the car runs perfect except for the WOT crap.

I thought the WOT problem could be the TPS sensor being wired wrong SO I checked it and it was wired opposite of stock just like everyone said to do it and the car NEVER ran past 1500 rpm. So I wired it back to stock and it runs great except for the WOT problem. WTF

Any ideas ? ? ?

 

Not to be a smart *** but if the car ran perfect then codes<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Dent Free &raquo;</TD></TR><TR><TD CLASS="quote">4,9,10,14,and 20 QUOTE] would not be flashing and the car would not have problems [QUOTE=Dent Free]I

Congrads on your swap.

Ok, for your codes....

4 - crank angle, white/orange wire on the dizzy. Suprised you can go over 3K rpm
9 - cyl sensor, also dizzy wiring
10 - intake air sensor - on the side of the intake
14 - electronic air control, never had it
20 - ELD, in the under the hood fuse box, tricky. Normally a bad ground.
