got a problem running
 

ok i just got a 87 turbo 2 i can start it it runs for like 15 20 mins some times less then it dies and if i try to start it it just keeps on cranking over and nothing will not start back up. after it cools down it will what could be wrong

Could have some fueling issues. Leaky injectors, etc. Search around on this forum and you should find a lot of info.

Could be the coils, after they warm up the stop sending current to the plugs, then after the cool down the start working again.

ya i just changed the coils still the same oh i can get it to start if i floor it when its warm but it miss fires under a load when i drive it down the street

You mean if you hold the accelerator down while craking it it starts? When you floor the accelerator and start cranking it cuts fuel so you can unflood easier.

The accelerator to the floor does not work to unflood engines on the S4 models. That is something that is built into the S5 models.

ok i got the car to stay running but still have to floor it to start it to give it more gas i think i beginning to think mabe not getting enuff fuel if i drive it down the read as sone as it gets positve boost it seams to miss fire
