that is called stalling
the PCM works OVERTIME to prevent all stalls
there are over 50 causes of stalls. and about 4 or 5 in pure physics.
we can do 2 things, guess, and tests
testing takes tools ,
got tools and the gauges?
I can tell you each test. but the story is long,,, and id bet you want gue$$ing (last)
- lost 12vdc to EFI or spark systems. (dead battery? blow or loose fuse//?
- lost engine compression 1 or more cylinder, hot only?
- bad spark , do a tune up now.
- lost fueling or flooding, (a new fuel filter can help if its not inside tank as the stupid EPA put it....... dont ask.......
- ISC is stuck (IAC-electric) the ISC can gum up and the ECU can no longer control idle speed.
the first tests are free.
- can your fast acting right foot save the stall?
- can you start car with WOT, this clears flooding.
- can test fuel, start engine when it dont want to?
wot (this is in the oper guide) means wide open throttle,
while cranking this magic trick , cuts all fuel and clears all flooding.
that is it, all else takes tools. no tools no joy. sorry.
