Just recently bought a 96 blazer,ran fine for a couple weeks then recently while driving it starts to hesitate when pressing gas pedal and while at stop lights it has stalled on me.somedays it doesnt do it at all and other days it will do it constantly.it has no check engine light on,have replaced fuel filter,air filter,pcv valve. had it in to get coolant flush tranny flush and oil change.will be doing spark plugs also.i have even put in some sea foam to a tank of gas.any ideas what else i should do??

 

First thing you can do is fuel pressure leakdown test https://blazerforum.com/forum/2nd-ge...eakdown-88305/

 

Same issues here although it hasn't died on me in quite some time. I'll just say what I haven't done yet...lol. Plug wires, ignition module, distributor (but did replace cap and rotor) pcm computer. Still has the small bump or miss, stall whatever you want to call it.
If I ever find the culprit I'll will post the answer.
Later Guys
