i did a lot of fidlling today trying to figureout why my car kept stalling out every damn time i came to a stop..

did leakdown test ----2.5% all the way across
compression check----175 all the way accross
so i didnt hurt the engine this weekend,

i thought well maybe plugs ----nope they are perfect no signs of detonation
o2 sensor maybe ruined by leaded gas----nope
finally i check the blowoff valve and adjust hardness and tune on the laptop and try more or less timing and fuel----nothing helped

looked for leaks in piping and vacuum...

nothing i finally reset the ecu and problem solved-----the fuel trims were all screwed up from trying to compensate for C16...
when i put 93 oct back in it went crazy....so if all else fails reset it. i got my old idle back emmediately.......

 

ggod to know. I will be using race fuel this weekend
