Well  finally got the temp II sensor replaced and radiator  has been bleed.
Runs real nice and i am getting 18 mpg in town.

New problem. Vans at normal operating temp. I shut it off and restart  the
van will idle till i am under load will hesitate ,loss of power, slight
backfire. I shut it off and immediately restart runs great no problems This
all happens under 35-40 mph I am affraid to try to get it going any faster.
Any ideas ?  I have checked fuel,pressure,regulator ,timing , plugs ,
electrical o.k.fuel pump , o/2 sensor

I have a 86GL automatic a.c. original engine and trans with 196,000 miles
