My car has recently started running rough after about 1 mile. Doesnt die or anything like that, but kinda sputters. Check engine light came on so i pulled the codes. Got code 26. looked it up to find out what it meant but still kinda lost. Any ideas on wht to check. Thanks for your help

code 26 is a quad driver. that's a really nebulous code, IIRC.

what is the maintenance history like? recent tune ups? fuel filter?

have you tested the fuel pressure?

No I havent checked fuel pressure. Gonna change fuel filter sunday evening after work or monday morning. This was just brought up by a friend the other day that that could cause these problems. As far as tune up. Myself havent dont anything major like plugs and wires since i've had it. Know the car was taken care of by the previous owner. Gave me reciepts and things where he had the car maintained.

start with the simple stuff. then work up from there.

I don't have a book on early LT1s but knowing that your engine's is of a batchfire design, "quad drivers" sounds like it is a code having to do with that, since batchfire systems fire one bank at a time. "Drivers" is a term associated with the ECM, as in "injector drivers." You definitely need access to a factory service manual.
