i am out of ideas so maybe you all will have some. Car is a 96 ta. It is very hard to start when you first get in and wont idle very well once it does start. After it warms up it runs smoother and idles pretty good, but when i get it on the road it starts cutting in and out. Has some sort of miss to it i guess you would say. I have changed the plugs wires and opti, which made a big improvement, but its still not right. I have also recently changed the fuel filter.the engine isn't making any bad noises or anything so i don't think its anything internal. Any ideas where to look next ?

I have been meaning to check the fuel pressure, but i got to wait tile Friday to get a pressure gauge, spent all my money on parts that didn't fix the car. For now i am going to triple check the firing order. Maybe somehow i f*ed it up.

buy a haynes manual.
the icm's are make/model specific! one from a random *** vehicle in a junk yard is prob junk!
first and formost, check the fuel pressure!
And you dont want coolant shooting every where!that will ruin the opti! you can buy a gauge on ebay that will mount on the rail and you will always know what your fuel pressure is for about $30!
check the injectors for proper readings!
check the coolant temp sensor for proper readings!
i'll start the bidding @ a thou (1000)!

FYI All a ICM does is read a signal from the pickup coil or(Hall effect sensor in the distributor), and provides a ground for the coil enabling it to create spark. The pickup is what controls when the ICM provides ground for the coil NOT the ICM itself. If they were different the part number would be different, call your local part store and tell them to cross reference the ICM for a 96 Blazer with a 4.3, to a 96 Trans AM, they will give u the same part with the same number.
