93 ssei cutout problems (detonation)
My car runs will barely take any boost once it has been running for about 30 minutes. It hesitates and cuts out very bad like I am running very very low octane fuel. Could the problem be bad gas. I filled up then went on about an hours drive, about 45 minutes into it it started doing this.I added octane booster and tapped off a 3/4 full tank with 93. It seemed to help, but still after driving 30 - 45 minutes it starts the same thing.
It is either something electrical or just flat out bad gas. I am trying to run it all out to see if that fixes it. Any ides???????

2) How many miles on the car since you changed the fuel filter? Maybe it'* got some flow problems. I'm thinking more fuel-related than ignition-related problems here if you see some difference in performance when you change the fuel mixture like you did.
The fuel filter is under the car, inboard of the passenger'* side subframe behind the front wheel.

Replaced fuel filter, same thing. Is there something that may be getting too hot (like coill packs) that could cause this. I can let it run for 10 - 20 minutes in the driveway with hood up and all is fine. But if I keep the hood closed or drive it, once everything gets nice and hot it starts this. I haven't checked fuel pressure, but wouldn't think that would be it since it runs awsome from until fully hot (20 - 30 miutes runtime). If I shut off car, and restart it a few minutes later it runs great for a few minutes then starts acting up again.
Need advice?????
