What up first of all.
I have a 1984 SVO and cannot figure it out. Here is one of the problems. It will be at idle(high idle) 1200 rpm and the AFR is like 16-17:1, that is ok. It runs fine when it is like that. Then all of a sudden it will drop to 700 rpm and the AFR will go to 21-22:1 that is very lean and it sounds like it has a monster cam(which would be ok if it did). Also it will cut out at like 6000 rpm and take forever to recover. It will spit and sputter for a while and if I let off the gas it will die. When I attempt to restart it it sounds like a car that has a broken timing belt(spins very freely). I will have to wait a minute for it to start.
Any ideas? I have checked the TPS voltage, VAM voltage and so on. The computer is a "TE". I also tired to run a self test with my scanner with no luck. I even checked the continuity(forgive me if I spelled it wrong) and all the self test wires checked OK?
Any input would be great, Thanks, Donavan
