been trying to hunt down a low idle in a 1990 auto. idles at 550 -600 in gear and vacuum drops to 8 (at 12 in park). does have a 520 cam. Motor mounts new.
TPS at .85 and then 4.58 at wot (runs up smoothly)
Fuel pressure 32 koeo then 33 at idle and 38 with vacuum line disconnected.
I think it's several small vacuum leaks in the intake. The most difficult being that bypass shaft. Is there a kit?
Thanks
Larry
