I just recently went through a bunch of not starting issues... bottom line I had to replace the ECU. So I get it replaced, fire it up and its idling at 3000 RPMS.... Heres what I checked:
-checked all vac lines, they appear good
-checked the throttle body out, the blade isnt even open when its doing this
-the throttle cable isnt binding or catching
-the only way I can slow down the engine is have it in gear and use the gears to slow it down
-if I press the clutch in, the idle shoots up again
-I sprayed around the engine bay to check for leaks and found nothing.
-when I open the throttle, the blade opens up and it revs higher
-I plugged the little slit in the throttle body inlet and the idle didnt change.
The only thing I could suspect is that I replaced all my fusible links with inline fuses because I trust them more. 4 total. Each one has a 30 blade fuse in it bc I didn't know what size to use. Could this be throwing off readings in the ECU?
Could they have sent me the wrong ECU?
Any help would be awesome!
I need some help because even though I was able to drive it around, I will burn up my clutch fast that way and obviously I need it normal.
