I guess I can do that. I'll change the fuel filter tommorrow. and as far as the fuel pumps go it still runs right up to the redline


How long ago since you chaned the fuel filter?
How is your fuel pumps(intank&outside)?


I have a cam sprockets and a Turner chip on a 91 s38.
when I'm at half to wide open throttle, from about 1500rpm to redline, the motor sputters and lays down between 1500rpm and 2500rpm, then again at around 4500 rpm then runs . when I say sputters its like its not firing on all the cylinders or bogging down.
This is what I've checked.
1. all the wires(plugs, coil, misc. connections on motor) are firm in their connections
2. the charging system is in woking order
3. the battery is good.
4. (In CT) thought it could be bad gas so I filled up with Sunoco 94 octane added NOS +7 octane boost and Cheveron tectron additive.

needless to say it still run like sh%t.

Anyone have any ideas or comments.

Mark W.
