also, air leaks do not cause vibration, just like using, right foot for 1500RPM , causes no abnormal vibs.
vibration means misfire.
sounds like limp mode to me, or bad spark plugs or wires. use MAG wire on this car, not carbon core or nasty silicon core, mag gives you lots of good spark levels.
spark plugs need to be at gapped at .028" spec. 0.7mm
vacuum leaks are discovered by the MAP sensor and it with ECU sets fuel mix perfectly for any vacuum leaks, on this car, very unlike the 16V car with MAF.
This perfectly means no misfire. with vacuum leaks so tell me there 2 problems, but most cars this old are RIFE with problems. so .. nothing new there.
not with standing bad vacuum hose to MAP , bingo huge vibrations, and bad fuel mix. super rich mix , so this hose is first. (for a clean burning engine)
good luck to you !!!!
