I tried some Bosch(Ford)19# "take out" injectors I got from
www.fiveomotorsport.com that my 360 just didn't like. Bruce sent me two
different sets and both acted the same.
The engine started fine when cold but then the engine would stall
frequently. The only way to restart it was to open the throttle and crank
it. It was like it was flooded. I put the original Siemens injectors
back in. The orginal ones gots to be somewhat worn out at 310,000 miles
but today I passed our Georgia emissions test with no problems.
