idle problem

[shoota143]

car will idle around 500rpm, idle does vary from up to 1100 down to 400, but is at 500 most of the time. After i start the car it will idle roughly missing every regularily. if i rev the engine it will die 90% of the time, doesnt matter how high i rev. i was told the timing might be off, i find this hard to believe b/c i just changed the timing belt 3 weeks ago and marks were lined up. i put in new plugs and plug wires..could it be the coil? ECU? wanna check b4 i buy anything..and info helpful Thanks!

Edit - i also have alot of shaft play in my turbo

Did it do this before the timing job? If not I would recheck your marks and go from there.
Did you make sure your tensioners were tight and healthy? I don't know if your car has a hydraulic tensioner like the stock turbos do, but if you do it can go bad and reduce tension.
