1986 1st Supra Running Poorly

dlfred · 04-04-2010, 10:24 AM

The wire is broken off flush with the back edge of the connector on the harness side.

I think getting this ACIS system working first may take care of most of the running issues.

The 3 sensors we are talking about, are they only on the NA's?

Would this explain why the car runs on 5 cyl. and the will skip into a 6 cylinder running mode?

Thank you again for your input.

I found a connector at the junk yard for $5. Nice. So the car idles much better but still will not pull under hard acceleration. Roll out of it a little and it feels as though the motor adds a cylinder and pulls smooth. It seems to get better as it gets hotter, not good, just better. I did the vacuum test from the manual and I have vacuum when I shouldn't or don't have it when I should.

Any ideas? Thanks
