What's up guys I'm new here and this site has helped me a lot in the past. I have an 89 2.3 5 speed it has a Jasper motor in it and I've been slowly replacing the little things. I'm having some problems with the idle tho it when I start it cold it'll run fine but after a minute bog down till it almost cuts off I've just put new plugs wires and a fuel filter in it. Looking at some fuel system cleaner and cleaning the MAF and possible a new O2 sensor. Anybody have any other ideas? Also the check engine light tends to bounce on and off around 3 thousand rpm. Any ideas?
 
if what your changing doesnt help (o2 sensors and clean the maf) the idle problem is probably going to be your idle air control valve. what is the truck doing at 3k is it pinging fluttering or anything like that?
