1997 tahoe, shuddering at highways speeds

only when I ease up on the accelerator.

it flashed a code, it scanned to show p300 something random/multiple cylinder misfire.. then a coupld of days later the light went off, but the shudder still happens.

I just replaced the fuel pump, and this started immediatly afterwards.

its not starving for fuel, if you floor it pulls steady and hard from dead still to 90mph, but when you ease off of the gas at 70 or so it shudders..

Ive heard the front cv shaft could have a bad Ujoint causing this, Its on my list of things to check, but I wante to try and get some input from you guys, all ideas are welcomed!

thanks!
