MIssing under a load at low rpms?

[Jacob_Royer]

My car had an ocasional 'hiccup' now its more frequent and you notice it under loads at low rpms (under 2500rpm or so) Im thinking plugs/wires which usualy causes the problem?? I was going to pickup plugs for it because it has new LOOKING msd wires on it and i hate to get rid of them if they are good.. Im also picking up a fuel filter as it looks like its never been off the car.. Car was a 2owner the last owner was a girl that didnt drive it but 10k in 2 years so im sure she didnt know anyhting about maintnence.. Heck when i bought it from a car lot the dam u-joints where so bad that it shook like the car was going to fall apart when you got over 65mph!

Replaced the plugs today with bosh platinum 2's and it still was missing a bit then i blew my intake gasket! so i think it might have been the problem in the first place.. PI time i guess.. what years work??
