mising on four cylinders
 

well my 90 eldo is missing on cylinders 3,5,2,8. i got good fuel pressure new egr new cat and a few other little thing any suggestions i was thinking timing it has just over 60k on it.

I'd be looking for a big vacuum leak, considering the cylinders that are not firing/missing. Could be an intake leak, a hose cracked/damaged/off, or could also be the EGR that was changed. Did it have this miss before changing the EGR?

What engine is it, btw?
