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? |

It is exactly the same only at idle. The part load is different with the 1.7l one leaner and at WOT the 1.7L MPS is WAY leaner.
You are playing with fire as the engine will run hotter and could drop a valve seat.(as Dave Darling). I have the same basic test equipment as Brad A. and have tested lots of factory sealed units and rebuilts. Get the right one as the factory had a reason why they are different numbers for different engines Geoff |
