seems to die out when it idles

[#1 laser]

i have a 90 laser and it seems to die out when it idles but when im driving it runs alright i think my timing is off below 1500 rpm it misses and after 5500 rpm it sputters to me i think it might two things my timing or a boost leak but i do have two things wrong that might be the problem my o2 sensor is completely shot and my knock sensor is bad could those cause my car to miss and sputter at high rpms

ok i put in the o2 sensor and a knock sensor it stilll sputters but not as bad and it still wont stay started

Possible fouled plugs or ignition problem?

Have you pulled your ECU to see if it's good. Get all the base line stuff done first and if that does not do it start digging deeper.

ok i just gave it a tune with new plugs,wires,oil change but still the same i was told to check my injectors that might be it cause when i bought the car the o rings were bad on all them

Airflow sensor . unplug it see if anything changes .

Could be massive boost leaks . How long has your bov been attached to your uicp like that ?

i thinks its the timing but it also might be a boost leak i bought the car with the uicp it had the bov like that why is the the wrong way

k i found some boost leaks my cuplink between mmy uicp and the intercooler had a big hole in it i replaced that and the gasket on the turbo that the intercooler elbow connectes to was bad and i got that but i just found out that im shooting a blue flame out my exhaust
