OLDSMOBILE 98 ENGINE PROBLEM

1993 Oldsmobile 98 • 149,000 miles

I have a shudder when I first start my 93 olds 98 touring sedan supercharged. It will do this for 1-2 mins then idle pretty good, It also shudders when accelerating. Hills! It isn't good. I have replaced plugs and wires, TP sensor, IAC valve, 1 injector, new gas cap, fuel filter. I have no Check Engine lite come on and there are no DTC stored in the computer. Please Help! Thank you.
