ECM is probably going bad... Try heating it with a heat gun... Sometimes that will trigger a shut-down and let you know if that is it.

It could be the mass air flow or manifold absolute pressure sensor (MAP) ; usually has just one or the other. The idle air control valve can also cause this. Sometimes the O2 (oxygen) sensors can cause this as well. If it runs fine going down the road then I would check the Idle Air Control Valve first.

I started the blazer and it is idleing really rough. then I get a mile down the road and it dies on me. I just replaced the thermostat and fuel filter bc it wont hold antifreeze and keeps overheating. What...


The loss of coolant, overheating and running bad could add up to coolant leaking into the engine. The Dexcool antifreeze used in the GM vehicles has caused gasket failures in the upper air plenum and the lower intake manifold. This could allow the antifreeze to be pulled into the combustion chamber and the oil. If there is no visible external leak, then this is probably what's happening. Sometimes the gasket leak will show up as a very small and difficult to detect puddle somewhere around the gasket/engine mating surfaces. Also look for signs of coolant in the oil. If it has gotten into the combustion chamber, then it has probably ruined the O2 sensors and catalytic converter. The only solution is to pull the upper and lower intakes and replace the gaskets. Change the oil and filter. DO NOT put Dexcool back in the radiator. Use a green antifreeze that is labeled compatible with aluminum engine parts and radiators. Replace the O2 sensor. The catalytic converter might have survived. Get it running first, then worry about the converter. Good luck to you, and try to have a Merry Christmas.

Car dies unexpectedly sometimes starts soon sometimes takes a day, replaced fuel pump already.


Check the Catalytic Converter. Sometimes when they get plugged the guts will settle down when cold but once they are warmed up they expand and starve the engine.

Did you know Jeep did a recall and paid for replacement of catalytic converters on 1996 models (don't know about any others) - they reimbursed me for work done, up to a point - hope this helps!
