Been tying to figure this out for my buddys Crx for a while know and cant fix it. I used to own the car but before i sold it to him It was a 89 CRX DX DPFI, then i converted it to MPFI with a SOHC in it. Sold it to him later down the road he got a LS swap for his car and wanted to convert it to OBD-1 So he bought a Jumper harness from OBD-0 to OBD-1. Ever since we did this pulls a code 14 and the EACV does not turn on cant hear it click when i plug it in or unplug it changed it with 3 good known ones and still doesn't work any ideas. Owww yes and the other things it does is when you rev it past 1000 RPM all the way up to 2500 RPM it just fluxuates (think i missed spelled) up and down like crazy but after 2500 runs fine. well anything will help me out guys thanks for the help guys.

check the conversion harness, i heard 1 out of 500 chances that a harness could have misplaced pin accidentally by the people putting it together, this was what happened to mine . Send the harness back and let them check it to make sure it works, where did you get your harness btw?

 

bump, and thanks for the info crx-control.
