I just did a shake down run to see if I could get it to stall

and I wasn't able to but...When I start the car (it takes more cranks than it should)
then it starts and the RPMs are at 500
it sounds real slow bearly sounds like a diesel (603.961 is pretty quiet anyway)
then it will go up to 700RPM or so

I shut it down again start it same 500RPM I bump the throttle goes to 700 or so

I did some mash your motor hard brakeing manuvers
so slow speed turning stuff
hit it let off the throttle

not everytime but sometimes it was dropping down to 400-500rpm and almost stalling out

Iam just throwing this out there
it seemed it was dipping down to these low rpm's
in conjuction with the trans shifting

example from a stop hit the throttle just as it up shifts I let off and rpm's fall

Or as I slow down it down shifts to "the stopping gear or idle gear" I've heard they start in 2nd some time 1st what ever it thinks is good at the time?
I will check out the timeing tool deal
I want to do it myself because I do everything else myself I don't really want "A shop" to touch my car
You wouldn't want anybody else to touch your girlfriend or wife right! To me there isn't much differance
