stutter reving

[slim2005]

Ok all, long story to get to point,
I'm about tired of dsms, but i'm addicted . I let my car sit a couple of days due to not being able to work on it but when i got back to working on it i had to replace the battery. Then the factory Tachometer wouldn't work, checked connections behind intake manifold and started it again and it worked. I then let it sit a day and i pressed the stupid valet button and it wouldn't start. Got it turned off and fuel pump was on again and just heard a noise when key was turned. I then checked starter connections and wiggled what i could. Car then started.. NOW to te problem... It idled a little funny like it had big cams for about a minute and a half and now idles fine. But when you rev on it at about 2200 RPM til 2600-2700 RPM when it gets there it stuttters and cuts out. before it revs fine and after it revs fine... not sure what the deal is... Also When i start it the starter sparks a good amount... but goona check connections again on that tomorrow. Anyone have any ideas or tips for the stuttering. plan to do vacuum leak test and check plugs but i did vacuum test just a short time ago like 80 miles ago. Thanks all

Might need to clean/replace injectors

will give that a try also anyone else?
started it a little while ago and it revd ok but idle bounced a little bit like maybe 100 RPMs uo and down,

you might want to check your spark plugs and the check to make sure you have the right fireing order.

ok it did it once again... its real slow to accelerate from idle then just explodes like it used too. also idleing real funny, revs up and down a little. thanks for the help

check for boost leaks. check your plugs

It can be your power transistor,make sure its plugged in snug or you might just need to get a new one.

Like stated above check you injectors and plugs. Also Search Idle surge because that is was the idleing up and down most likely is. What all work have you done to the car to gain these problems??
