hi
i have a 85 gs 12a , 77k
i have been doing a lot of searches on here about starting problems,
my car starts up cold with no problem but after it warms up
it doesnt want to start again until the motor cools.
my question is would doing the MMO treatment help restore compression? i havent had the compression checked at mazda but according to all the threads that could be it. I Don't know

any help would be appreciated

 

have you tried checking for spark on the leading plugs, may be something breaking down from the heat, keep us informed on what u have tried, we are here to help,,good luck,
