I have a 1997 2.3, when I start my truck the first time in the morning it idles fine. I drive about 15 20 mins turn it off. When I start approx an hour later it idles fine for a minute or two but then it starts to shake and and feels like it gonna die. Any ideas just changes my wires and plugs but that didn't help. Any ideas?

 

clean all air intake sensors from filter to throttle body.

and check for vacuum leaks. I recently had an EGR leak and it was pulling unaccounted air and the truck would stall after 10 minutes of driving. fixed the leak, fixed the truck

 

mine had that after i went mudding and got the MAF dirty. cleaned it with some MAF cleaner and everything went fine.
