cooling fans come on car dies out at idle

Post by awdwagon »

Hi

Ok so just did the 5 speed swap in my 1991 subaru legacy turbo. and i sniped the wire that the ecu telling the car it has a manual and not an automatic its a black wire with white stripe can anyone confirm that?

2end of all now that i have sniped this wire the car will start and run normaly BUT when it idles @ 900 rpm's as soon as the cooling fans kick on the car will want to die out or have a super shety idle and then die out has anyone else had this problem???

Yeah it should be black with a white stripe. You sure you snipped the right connector?

Did you remove the TCU?

I was also wondering, do you have to do anything to that wire? just snip it? or do you have to ground it out at either end?

Is this maybe just a case of the computer needing to figure things out?

My car doesnt have any real problems with it hooked up, just seems to "hold back" sometimes, and other times it goes like a raped ape. I didnt do alot of the wiring things that others have done. I left the selector switch from the AT shifter in the car and in park, I can start it without the clutch but who cares, and my cruise just worked. SO maybe I need to go back and do all those. WHen its holding back it seems to be cutting timing, my air fuel gauge reads the same and it boosts the same, but sometimes it just doesnt have the get up and go that it should (well prolly most of the time to be realistic!) and then sometimes it makes so much power it overpowers my relatively weak 2.5rs clutch.
