My 2.0 started running rough a week or so ago, and I started checking everything by process of elimination.
Valves ok
timing ok
dwell ok
fuel pressure ok
Tps ok
c.o. ok
Purchased new vacuum pump today. Guess what?
Zippo. Nada. Nothing. would not even pump up. Grabbed a mps from a 1.7. held at 20 for six minutes.
Car runs much better, but not perfect. are they different? can it be readjusted to work on the 2 litre?
