Gene93lx

Hey guys, I have run across a problem I cannot seem to find the answer to. I have a '93 lx 5.0. After doing a tune up and putting a smog pump eliminator kit on it my car started to shake between 900 to 1500rpm. Sometimes its a little bit and at other times it feels as if my car is going to shake apart. Since then, I have put it back to the stock ignition components and put the smog pump back on, changed the fuel pump and filter sincethey werebad and even replaced the ignition coil hoping for anything to help. I thought it may be the MAF but it seems to register when I unplug it and plug it back in. The only ecu codes I can get out of it is unbalanced fuel injectors or insufficient fuel pressure.??&gt;?? Any ideas? Thanks for the help.</P>

in your tuneup what did you all do???

all i did was wires, plugs, rotor, and cap. Nothing serious.

i'm starting to think i have a leaky injector. Other than that I have no idea what it can be anymore, if anyone has any ideas please let me know.
