This is only a suggestion because it worked for me. With a cool engine, use a can of store brand carb cleaner and spray the heck out of it. Get it into the linkage well and let it sit for up to and hour or so....stuff some rags on the intake manifold to soak up the excess. Then, after letting it sit, get your 'Burb up to operating temp. Should be the ticket for you....and no, your engine won't catch fire.

When cold my '93 suburban dies but once warm runs fine it has a 454 with tbi


Have you checked to be sure the idle air control is working properly and also the engine temp control sw. The iac only comes on to maintain the idle when the engine is cold. The ect sw monitors the outside temp and tells the computer how much fuel to put to the engine. Hope this helps.

Serpentine belt squealing


Either the belt has stretched, or the tensioner is not keeping it tight.
Or it has oil on it.

We have a 2003 chevy suburban 5.3 vortec it dies when warmed up


Sounds like either Air mass sensor, Air mass meter or finally the EGR valve this is the exhaust gas recycler I would say that is the fault when they start to go this is what they do until finally the car will barely move.

Also I would check all your air pipes for leaks make sure there is no rips or tears in the pipes, The car will drive fine like you say until you ease of the gas to a stop position it **** in to much air and kills the engine. Air faults are cheaper so look there first.

Hope this helps

Car dies while driving and will not start up


Does it start after cooling down? If so then you have a bad ignition module located in the bottom of the distributor.

91 jimmy starts cold, runs rough hot, dies when put in drive


Try to unplug the mass airflow sensor and start it. It will idle higher but should run fine. If it works then you need a MAF sensor. Be sure you have an OBDII code puller to clear the computer when done
